Surface field launch stage in the bundle schema from cli.json

Read launch_stage, enum_launch_stages and enum_descriptions from the
checked-in .codegen/cli.json and surface them in the generated bundle
schema and docs:

- Prefix field descriptions with [Public Preview] / [Public Beta] /
  [Private Preview] so the stage shows in editor hover tooltips.
- Emit the parallel enumDescriptions array so VSCode renders a per-value
  stage label and description in autocomplete dropdowns.
- Carry the raw x-databricks-launch-stage alongside the existing
  x-databricks-preview, and hide PRIVATE_PREVIEW fields via doNotSuggest.

cli.json is filtered upstream at min-stage=PRIVATE_PREVIEW, so no
DEVELOPMENT surface reaches the extractor and launch_stage is already
clean (GA plus the three preview stages). The OpenAPI-spec-based
DEVELOPMENT filtering and preview normalization the earlier version
carried are no longer needed.

assignAnnotation flags an open question (in a comment) on whether either
x-databricks-preview or x-databricks-launch-stage is consumed downstream
of the published schema, pending confirmation with the team.

Regenerated jsonschema.json, jsonschema_for_docs.json,
annotations_openapi.yml and the bundle docs.
