ci: install [dev,crypto,smart] so signing/embedding tests run in CI

The second CI failure was the same root cause across test_pool, test_pool_github,
and test_review_fixes: pynacl/blake3 aren't installed in CI (by my dev-only design),
so the pool falls back to UNSIGNED mode — `pull()` returns [] (require_signature
rejects unsigned) and the identity-swap test sees an already-invalid signature. Those
tests assume the optional crypto deps rather than skipif-guarding their absence.

Fix: install the optional extras in the test job so the suite runs as written.
Honest trade-off (commented + tracked in roadmap): CI no longer exercises the
zero-dependency degradation paths; restoring that coverage (skipif guards or a 2nd
minimal matrix leg) is a follow-up. The engine is still zero-dep — this is a
test-coverage gap, not a code gap.

 ## Known gaps / honest notes
 - Recall ranking is semantic (embeddings) when the model is installed, keyword FTS otherwise; both feed the same blend + a corroboration bonus.
