fix(handshake): persist revoked trust cooldowns across daemon restarts (PILOT-237)

[matthew-pilot]

What failed

handshake.go:86 declares revoked map[uint32]time.Time as in-memory only. RevokeTrust() adds a 5-minute cooldown and calls saveTrust(), but saveTrust() only persisted trusted and pending — not revoked. On daemon restart, loadTrust() restored trusted/pending but left revoked empty, allowing a stale relayed-approval message sitting in the registry inbox to immediately re-grant trust to the just-revoked peer.

Why this fix

Add Revoked field to trustSnapshot and a revokedSnapshotEntry struct. saveTrust() now serializes non-expired revoked entries alongside trusted and pending. loadTrust() restores non-expired revoked entries and silently drops expired ones (defense-in-depth against clock skew on load).

Verification

• go build ./... — passes
• go vet ./... — (pre-existing test-file type issues in other files, unrelated to this change)
• Added TestSaveLoadTrustRoundTripPreservesRevoked and TestLoadTrustDropsExpiredRevokedCooldowns

Summary

Persists revoked trust cooldowns across daemon restarts. Adds revoked to the trust snapshot serialization so RevokeTrust() entries survive restart — preventing a stale relayed-approval message from re-granting trust to a just-revoked peer.

CI

Test check failed (10s run). Check the run for details — may be a flake or a pre-existing issue.

🦜 Matthew Explains — #6 PILOT-237

What this does

Persists revoked trust cooldowns across daemon restarts. Before this fix, RevokeTrust() set a 5-minute cooldown in memory but saveTrust() only serialized trusted and pending — the revoked map was lost on restart, allowing a stale relayed-approval message to immediately re-grant trust.

The fix

• Adds Revoked field to trustSnapshot struct for serialization
• Adds revokedSnapshotEntry struct for per-entry persistence
• saveTrust() now serializes non-expired revoked entries alongside trusted/pending
• loadTrust() restores non-expired revoked entries, silently drops expired ones (defense-in-depth)
• New tests: TestSaveLoadTrustRoundTripPreservesRevoked + TestLoadTrustDropsExpiredRevokedCooldowns

Verdict

Small, focused fix — 2 files, +75/-4. The change is self-contained: extends serialization without changing the trust-evaluation logic. Test coverage covers both round-trip and expiry-edge cases.
