⚠️ Pin bump — supply-chain surface (guardrail #10).

Completes the family-wide full 64-hex SHA-256 seal security upgrade in mcp. 0.2.7 already carried measure-mirror v0.27.0; this bumps the remaining two:

Why: 16-hex (64-bit) seal truncation left a dishonest-sealer birthday-collision gap (~2^32). v0.2.0 seals with the full digest. Backward-compatible — legacy 16-hex seals keep verifying via prefix match, no ledger migration.

Safety: version 3-way consistent (pyproject/init/CHANGELOG 0.2.8). Resolves cross-repo CP1 (action/provenance pin-lag) + CP3 (provenance version). CI will confirm the pinned installs don't break mcp.

Completes the family-wide full-SHA-256 seal security upgrade in mcp:
0.2.7 already bumped measure-mirror to v0.27.0; this bumps the remaining
two pins (action-mirror fd46e90->fa1fc49, provenance-mirror 8edbbfd->321f84a)

no migration). Resolves cross-repo CP1 pin-lag + CP3 (provenance CHANGELOG
