feat(testkit): add T41–T45 Nostr identity lifecycle coverage (Refs #55 )

- T41: POST /api/jobs with valid Nostr token → nostrPubkey in response - T42: POST /api/sessions with valid Nostr token → nostrPubkey in response - T43: GET /identity/me returns tier, score, interactionCount fields - T44: POST /identity/me/decay (test-only, 404 in prod) → score decremented - T45: GET /identity/leaderboard → HTTP 200, array sorted by trustScore desc New endpoints in identity.ts: - POST /api/identity/me/decay — test-only (disabled in production via NODE_ENV check) triggers one decay cycle via new TrustService.decayOnce() method - GET /api/identity/leaderboard — public, returns top 20 identities by trust score New TrustService.decayOnce() in trust.ts applies one DECAY_PER_DAY deduction immediately without the 30-day absence threshold, enabling deterministic test coverage.

Alexander Whitestone	52babff31f	feat(testkit): add T41–T45 Nostr identity lifecycle coverage (Refs #55 ) Some checks failed CI / Typecheck & Lint (pull_request) Failing after 3s Details - T41: POST /api/jobs with valid Nostr token → nostrPubkey in response - T42: POST /api/sessions with valid Nostr token → nostrPubkey in response - T43: GET /identity/me returns tier, score, interactionCount fields - T44: POST /identity/me/decay (test-only, 404 in prod) → score decremented - T45: GET /identity/leaderboard → HTTP 200, array sorted by trustScore desc New endpoints in identity.ts: - POST /api/identity/me/decay — test-only (disabled in production via NODE_ENV check) triggers one decay cycle via new TrustService.decayOnce() method - GET /api/identity/leaderboard — public, returns top 20 identities by trust score New TrustService.decayOnce() in trust.ts applies one DECAY_PER_DAY deduction immediately without the 30-day absence threshold, enabling deterministic test coverage.
