docs: graduate plugins out of experimental mode (#603)
* chore: add __init__.py to engine namespace subpackages

Griffe (used by mkdocstrings) skips directories without __init__.py
when resolving module paths, which prevented the new plugins code
reference from rendering SeedReader, FileSystemSeedReader, and
Processor. Adding empty __init__.py files in engine/resources/,
engine/processing/, and engine/processing/processors/ aligns with
the convention already used in engine/mcp/, engine/models/, etc.

* docs: flesh out docstrings on plugin extension-point classes

Plugin authors now see meaningful descriptions for every field and
method on the bases rendered in the plugins code reference:

- Plugin and PluginType: class docstrings + Attributes tables for
  fields and enum members; fix typo in config_qualified_name field
  description.
- SingleColumnConfig: document allow_resize.
- ProcessorConfig: document processor_type discriminator.
- SeedSource: document seed_type discriminator.
- FileSystemSeedSource: add class docstring + Attributes table for
  path / file_pattern / recursive.
- ColumnGeneratorFullColumn and ColumnGeneratorCellByCell: add
  class docstrings explaining when to use each base, plus method
  docstrings on the abstract generate() implementations.

* docs: graduate plugins out of experimental mode

Restructures plugin documentation around the now-stable extension
points (column generator, seed reader, processor) and treats plugins
as a first-class story for customizing Data Designer.

- Add code_reference/plugins.md: single-stop reference for the Plugin
  object and the config + implementation base classes used by all
  three plugin types.
- Add code_reference/generators.md: column generator implementation
  base classes, separated from column configs.
- Surface SingleColumnConfig in code_reference/column_configs.md.
- Add plugins/implement.md ("Build Your Own"): per-type implementation
  instructions across column generators, seed readers, and processors.
- Add plugins/processor.md: complete processor plugin package example.
- Rewrite plugins/overview.md: open with why plugins exist, drop the
  internal-helpers note (PluginRegistry / PluginManager), and focus
  the guide on what plugin builders need.
- Refresh plugins/available.md (Catalog) and
  plugins/filesystem_seed_reader.md to match the new structure.
- Delete plugins/example.md (replaced by per-type guides).
- Reorder Code Reference nav alphabetically and add the new pages.
- Minor link / wording fixes in concepts/processors.md and
  concepts/deployment-options.md.

* docs: simplify plugin docs structure

Replace the overview's how-to walkthrough and the per-type plugin
guides with a single Build Your Own page that covers all three
plugin types side-by-side. Add a dedicated Using Models in Plugins
guide and a seed_readers code reference, and trim the overview down
to what the plugin types are, how to use one, and how discovery
works.

- Rename plugins/implement.md to plugins/build_your_own.md.
- Delete plugins/filesystem_seed_reader.md and plugins/processor.md
  (their content is now in build_your_own.md and the per-type code
  references).
- Add plugins/models.md for model-backed column generator authoring.
- Add code_reference/seed_readers.md for seed reader implementation
  base classes.
- Rewrite plugins/overview.md: shorter intro, type bullets link to
  the relevant code reference, drop the multi-step "How do you
  create plugins" walkthrough in favor of a single Build a Plugin
  pointer, tighten Discovery troubleshooting.
- Refresh plugins/available.md (Available Plugins): point to the
  DataDesignerPlugins catalog and explain how to request a community
  listing.
- Update cross-page links in concepts/processors.md,
  concepts/seed-datasets.md, recipes/plugin_development/markdown_seed_reader.md,
  code_reference/plugins.md, and code_reference/generators.md to
  match the new structure.
- Update mkdocs.yml nav: rename to Build Your Own, add Using Models,
  add seed_readers code reference.

* docs: scroll wide tables horizontally instead of wrapping

Code-heavy reference tables (plugin bases, column generators, etc.)
were wrapping aggressively on narrow viewports, breaking long
identifiers across multiple lines. Switch the table container to
horizontal overflow and prevent code cells from wrapping so
identifiers stay readable.

* docs: address PR #603 review feedback

- Add an Implementation base section to code_reference/processors.md
  rendering the engine-side Processor class. This justifies the
  engine/processing/__init__.py files added earlier and gives
  processor plugin authors an auto-rendered API reference, matching
  the pattern used by code_reference/generators.md and seed_readers.md.
- build_your_own.md: replace the placeholder "x" emoji on the
  IndexMultiplier example with the actual multiplication sign.
- build_your_own.md: drop the manual `re.compile + apply(lambda)`
  pattern in the regex-filter processor in favor of the idiomatic
  `Series.str.contains(..., regex=True)`.
- build_your_own.md: add a kernel-restart caveat after the editable
  install instructions — PluginRegistry caches discovery on first
  import, so notebooks need a fresh kernel to pick up freshly
  installed plugins.
- build_your_own.md: state explicitly what `assert_valid_plugin`
  checks (config base + plugin-type-appropriate impl base).
- code_reference/plugins.md: link out to the processors code
  reference alongside generators and seed_readers.
