chore(sync): expand .claude-sync.conf to cover 11 missing dev-docs

Following an audit triggered by amendment commit 0d4afcd not auto-
regenerating .claude-sync (because RFC-WS-FRONTEND-PRIMEVUE.md was
absent from .claude-sync.conf), this commit closes the gap.

Added (11):
- 2 PrimeVue migration docs (RFC + audit)
- 5 tooling docs referenced from CLAUDE.md (CLAUDE_CODE_TOOLING,
  FRONTEND-TOOLING, LARASTAN, RECTOR, TELESCOPE)
- 1 architectural policy (FORM_BUILDER_SCOPE_POLICY)
- 1 sprint audit referenced from CLAUDE.md (WS-3-SESSION-1C-AUDIT)
- 2 reference docs (COPY_CATALOGUE, TEST_SCENARIO)

Skipped (12) with rationale documented in chat thread: one-time setup
docs, sprint-bound audits, end-user docs, superseded precursors, and
duplications of CLAUDE.md content.
