feat(P05): seal/audit CLI + chain race fix + key zeroing (REQ-154)
New CLI commands:
- orca cluster seal: OIDC/CA-derived seal + Shamir 3-of-5 shards
- orca cluster unseal: OIDC/CA unseal + --recovery Shamir path
- orca doctor audit: VerifyChain + chain head report
- orca doctor modes: EnforceFileModes across ORCA_HOME
Fixes:
- audit hash-chain race: Append uses BEGIN IMMEDIATE transaction
(concurrent appends no longer corrupt tamper-evidence)
- secrets rotate-master: re-seals to OIDC on sealed clusters
(was writing raw key, docstring claimed re-seal)
- key zeroing: ZeroKey helper + defer after master/namespace key use
(defense-in-depth against pprof heap extraction)
- store.Open: busy_timeout(5000) pragma (concurrent writers wait)
Tests: 18 new test functions (seal round-trip, Shamir recovery, doctor
audit tamper detection, doctor modes 0644 rejection, concurrent append
chain integrity, rotate-master re-seal, key zeroing).

feat(P08): master key seal-to-OIDC + Shamir 3-of-5 (REQ-147, D-241, C-35)
---ci---
project: orca
phase: 8
milestone: v0.12
status: execute
---/ci---
internal/seal/seal.go: AES-256-GCM sealing with HKDF-SHA256 key
derivation from OIDC subject. Seal/Unseal (OIDC mode), SealWithCA/
UnsealWithCA (mTLS-only offline path), SaveSealed/LoadSealed (0600),
VerifySealedKey.
internal/seal/shamir.go: GF(256) Shamir secret sharing. ShamirSplit
(5 shards, threshold 3), ShamirCombine (Lagrange interpolation).
UnsealWithShamir for IdP-lost recovery (C-35).
9 tests: seal/unseal round-trip, wrong-sub fails, Shamir 3-of-5
recovery (multiple subsets), 2-shards fails, CA mode, mode mismatch,
shard encoding, verification. All pass. Full build + vet green.
