docs: close doc drift vectors — bidirectional parity, manifest, schema-driven config (#2479)

Option A — ghost-entry guard (INVENTORY ⊆ actual):
  tests/inventory-source-parity.test.cjs parses every declared row in
  INVENTORY.md and asserts the source file exists. Catches deletions and
  renames that leave ghost entries behind.

Option B — auto-generated structural manifest:
  scripts/gen-inventory-manifest.cjs walks all six family dirs and emits
  docs/INVENTORY-MANIFEST.json. tests/inventory-manifest-sync.test.cjs
  fails CI when a new surface ships without a manifest update, surfacing
  exactly which entries are missing.

Option C — schema-driven config validation + docs parity:
  get-shit-done/bin/lib/config-schema.cjs extracted from config.cjs as
  the single source of truth for VALID_CONFIG_KEYS and dynamic patterns.
  config.cjs now imports from it. tests/config-schema-docs-parity.test.cjs
  asserts every exact-match key appears in docs/CONFIGURATION.md, surfacing
  14 previously undocumented keys (planning.sub_repos, workflow.ai_integration_phase,
  git.base_branch, learnings.max_inject, and 10 others) — all now documented
  in their appropriate sections.
