fix: Invalidate cache of removed input sockets.
This was a nasty (interesting?) one - usually, input sockets are not attempted used
after the socket no longer exists.
Various checks in ex. `events` tend to help that process along.

Unfortunately (fortunately?), `Extract` uses a `_compute_input` query with
`optional=True`, which results in a direct attempt to hit the cache
without any other checks.
Because old input socket caches were never deleted, it would
**continue to get cached data from sockets that no longer exist**.

While on the surface this could be considered a case of "the
private method (`_compute_input`) is private for a reason", or
alternatively, "don't hijack the graph flow", I'm more convinced that
the usage is actually quite clean, being read-only and generally
well-conceived. It's reasonable to presume that asking for a thing that
doesn't exist won't produce output!

Moreover, I wouldn't be surprised if several other mysterious bugs were
caused by this. Not to mention the memory leak of endless caching! (Well,
until the node is deleted). It's a good things we noticed!

feat: Complete matplotlib plotting system.
The Viz node now detects the shape of the data, and presents compatible
plot options.
Not all are implemented, but a few quite important ones are.

Additionally, a number of dataflow-related bugs were investigated and
fixed. A few were truly damaging, but many simply resulted in gross
inefficiencies - we must be careful declaring BLFields that are updated
in hot loops!

Moreover, it is exceptionally easy to add more as needed, as we analyze
more and more sims.
The only limit is `matplotlib`, which is... well, yeah.

Due to the BLField work, the dynamicness of the Viz node is quite
under control, so there will not be any critical issues there.

The plotting lags (70ms total in the hot loop), but that's actually
entirely fixeable.
It's also entirely the `managed_bl_image`'s fault.
Fixing these inefficiencies will also make Tidy3D's builtin plots
near-realtime, incidentally.

We profiled the following currently:
- 25ms: Creating `fig = plt.subplots`. We can reuse fig per-managed
  image.
- 43ms: The BytesIO roundtrip, including `savefig`. We can instead use
  the Agg backend, `fig.canvas.draw()`, and a `np.frombuffer` to both
  plot directly to the memory location,
- ~3ms: Actual plotting functions in `image_ops`. They are seriously fast.
- ~0ms: Blitting pixels to the Blender image - this was optimized in
  4.1, and it shows; the time to copy the data over is essentially nothing.

feat: Safe, practical BLField.
BLField has gotten a huge facelift, to make it practical to wrangle
properties without the sharp edges.
- All the "special" UI-exposed property types can now be directly
  constructed in a BLField marked with 'prop_ui'.
- The most appropriate internal representation will be chosen to
  represent the attribute based on its type annotation, including sized
  vector-like `bool`, `int`, `float` for `tuple[...]`.
- Static EnumProperties can now be derived from a special `StrEnum`, to
  which a `to_name` and `to_icon` method is attached.
- Dynamic `EnumProperty` can now be used safely, with builtin
  workarounds to the real-world reference-loss-crash (realized
  in the Tidy3D Cloud Task node) and jankiness like empty enum.
- The update method is now fully managed, negating all bugs related to
  improper update callback naming.
- Python-side getter caching is preserved for ui-exposed
  properties, with the help of node/socket base class support for
  passing a `Signal.InvalidateCache` to BLFields that are altered in the
  UI.

The cost to all this niceness is rather low, and arguably, positive:
- Dynamic Enum/String searchers no longer "magically" invoke all the
  time, since the values seen by Blender are cached by the BLField.
- To regenerate the searcher output, an `@on_value_changed` should be
  made by the user to pass `Signal.ResetEnumItems` or
  `Signal.ResetStrSearch` to the `BLField`.
- Since searching is no longer eager, there is no danger of
  out-of-reference strings (which crash Blender from EnumProperty), but
  also a greatly reduced performance problems associated with
  the hot-loop regeneration of EnumProperty strings.
- The base classes are now involved with BLField invalidation, to ensure
  that the getter caches are cleared up when the UI changes. For the
  price of that small indirection (done cheaply with set lookup),
  all attribute lookups are generally done in a single lookup, completely
  avoiding Blender until needed.
- This does represent another increase in confidence wrt. the event
  system's integrity, but so far, that has been a very productive
  direction.

**NOTE**: The entire feature set of BLField is not well tested, and will
likely need adjustments as the codebase is converted to use them.

feat: High-performance math system and depsflow.
Enormously important changes to the data flow semantics and invalidation
rules. Especially significant is the way in which the node graph
produces a deeply composed function, compiles it to optimized machine
code with `jax`, and uses a seperately cached data flow to insert values
into the function from anywhere along the node graph without recompiling
the function.

A critical portion of the math system, namely the unit-aware dimensional
representation, is also finished. The `Data` node socket type now
dynamically reports the dimensional properties of the object flowing
through it, courtesy the use of a seperate data flow for information.
This allows for very high-peformance unit-aware nearest-value indexing built on binary
search.

Also, dependency management is completely ironed out. The `pip install`
process now runs concurrently, and the installation log is parsed in the
background to update a progress bar. This is the foundational work for a
similar concurrent process wrt. Tidy3D progress reporting.

fix: Caching now (seems to) work robustly.
The serialization routines are fast and effective.
Overall, the node graph feels snappy, and everything updates smoothly.
Logging on the action chain suggests that there aren't extraneous calls,
and that existing calls (ex. no-op previews) are fast.

There will likely be edge cases, and we'll see how it scales - but
for now, let's go with it!

fix: Revalidated cache logic w/KeyedCache.
This especially involved fixing the invalidation logic in
`trigger_action`.
It should now be far more accurate, concise, and performant.

The invalidation check ought still be optimized.
The reason this isn't trivial is because of the loose sockets:
To use our new `@keyed_cache` on a function like `_should_recompute_output_socket`, the loose
socket would also need to do an appropriate invalidation.

Such caching without accounting for invalidation on loose-socket change
would be incorrect.
For now, it seems as though performance is quite good, although it is
unknown whether this will scale to large graphs.

We've also left `kind`-specific invalidation alone for now (maybe
forever).

Sofus Albert Høgsbro Rose 7f2bd2e752
fix: A bug and a crash.
The crash: When a linked loose socket was deleted, the link remained in the
NodeLinkCache, and caused a crash when trying to ask the already-deleted
socket for removal consent. We fixed this by reporting all socket
removals to the node tree, so that links could be correctly removed
independently of link-change calculation.

The bug: The collection getter was cached improperly; Blender ID types
can't just be saved like that. We need to search every time. Performance
seems unaffected at first glance.

feat: Robust DataFlowKind w/lazy structures.
This is essential for:
- Representing ranges as bounds
- Arbitrary symbolic/numeric representation of spectral distributions
- Parametric representation and JIT of critical-path procedures.

Unfortunately this broke a lot of nodes in small ways.
Next step is to finish the low-hanging fruit nodes + fix the ones we
have.

feat: Implemented fit of experim. medium data.
It's only good for dispersive media; specifically, a text file with
three floats per line: 'wl n k'.
A custom script was used to convert Maxim's data.

It's very fast, and has a ton of options.
Only the most important are exposed in the node for now.

A bug in MPL plotting aspect ratio declaration on MPL axis object was
fixed by manually running `set_aspect('auto')` after the fact.
It shouldn't do anything, and it doesn't, other than fix the bug :)

Also brought the plotting function of the viewer to parity with
the 3D preview, so the "Auto Plot" button works as expected.

feat: Working logging, before- and after-deps.
We have a far more sane approach to nodeps now, which
allows us to essentially have two loggers - one that is
very useful, pretty, and clear, but requires a 'rich'
dependency, and one that is simple.
In this spirit, we factored out services/ too.

We can also set the initial console log level now when
packing the .zip.

There's still work to do with the actual flow for deps
installing / uninstalling.
But it should be far more robust now.

Finally, we have a barebones working `quartodoc`-based docs site.
It's super clever; see <https://github.com/machow/quartodoc>.
As it's "just" a quarto project with some python autodiscovery,
fleshing it out with ex. math, images, diagrams, and so forth
should be exceptionally easy.

As we develop, various linter-guided fixes are being realized.
This will be a long process, best done as we spiff everything up
in preparation for general release.
