Update the database docs generator to extract capability flag values
directly from Python engine spec class attributes (supports_catalog,
supports_dynamic_schema, etc.) and method overrides (cancel_query,
estimate_statement_cost, impersonate_user, has_implicit_cancel, etc.)
using AST parsing in the fallback path.
Previously the generator hardcoded False for all capability flags and
relied on mergeWithExistingDiagnostics to preserve manual edits from
the existing databases.json. This made it impossible to keep flags
in sync with the Python source.
Changes:
- Fallback AST path now extracts cap flags via AST with proper
inheritance resolution (mirrors lib.py has_custom_method logic)
- mergeWithExistingDiagnostics now only preserves score/max_score/
time_grains (Flask-context-only fields), not capability flags
- lib.py generate_yaml_docs now includes supports_dynamic_catalog
in its output, and skips base specs that would overwrite a real
product spec's flags for the same engine_name
- Regenerated databases.json with corrected flag values
