Greptile Summary

This PR introduces a new reflex-docgen sub-package and the underlying infrastructure to support programmatic documentation generation for Reflex components. It adds a doc parameter to ComponentField and the field() helper, then migrates ~95 component files from inline # comment style prop descriptions to field(doc="...") kwargs so those descriptions are available at runtime via get_js_fields(). The new generate_documentation() entry-point returns a structured ComponentDocumentation dataclass containing per-prop PropDocumentation objects.

Key changes:

• New packages/reflex-docgen package with generate_documentation() / get_component_props() public API
• ComponentField gains a doc: str | None attribute and BaseComponentMeta now correctly propagates is_javascript and default when rebuilding fields from a bare field(doc=...) call (fixing a pre-existing gap where is_javascript=None could be stored unchecked)
• uv.lock and pyi_hashes.json updated accordingly; monorepo workspace expanded to include packages/*
• One minor code-quality issue: four imports in __init__.py (get_type_hints, AnnotationSource, InspectedAnnotation, inspect_annotation) are unused, left over from an earlier implementation that parsed Annotated[..., Doc(...)] type hints directly

Confidence Score: 4/5

• Safe to merge after cleaning up four unused imports in the new package's init.py.
• The core logic is straightforward and well-scoped. The component-field migration is mechanical and low-risk. The only notable issue is four unused imports that are dead code from an earlier implementation; everything else looks correct and consistent.
• packages/reflex-docgen/src/reflex_docgen/init.py — contains unused imports that should be removed before merging.

Important Files Changed

Filename	Overview
packages/reflex-docgen/src/reflex_docgen/init.py	New docgen module that generates ComponentDocumentation from get_js_fields(); contains four unused imports leftover from a previous implementation.
packages/reflex-docgen/pyproject.toml	New package definition for reflex-docgen with appropriate dependencies (reflex, typing-extensions, typing-inspection).
reflex/components/component.py	Adds doc parameter to ComponentField and field(), fixes is_javascript/default propagation in BaseComponentMeta, and migrates several inline comments to doc= kwargs; a handful of non-JS fields (library, tag, alias, is_default) retain the old comment style.
pyproject.toml	Adds [tool.uv.workspace] section to include packages/* members, integrating the new reflex-docgen package into the monorepo.
pyi_hashes.json	Hash updates for all regenerated .pyi stub files as expected after the component field signature changes.
