FR-1 (A1-amended): test:workspaces enumerates the blocking set readably
(daemon + cli + tui); NEW advisory test:ui runs packages/ui vitest at will.
lint/build/build:package/test/test:repo byte-untouched — UI typecheck and
the shipped UI dist stay blocking.
FR-2: docs/reference/developing.md created — gates/lanes table, the no-UI-
sync norm verbatim (hooks mirrors unmaintained; a test:ui failure = moved
API contract signal, not a broken gate), the wording rule (experimental /
maintenance mode / best-effort / CLI primary — never 'deprecated'; zero
'deprecated' hits grep-proven).
FR-3: the diff is EXACTLY two files (root package.json + the new doc); no
doctor/bundling/ui.enabled/build-package/starter-skill changes.
