test: expand coverage + fix setup/ TypeScript errors

New test files (83 tests):
- src/agent-identity.test.ts — resolveAgentIdentity across locales/genders
- src/env.test.ts — readEnvFile parsing, quoting, edge cases
- src/jail-registry.test.ts — getJailIp with/without env override
- src/local-hosts.test.ts — block markers, entries, render, upsert
- src/mount-security.test.ts — validateMount allowlist enforcement
- src/transcription.test.ts — initTranscription + transcribeAudio with mocked OpenAI

setup/ TypeScript audit (tsconfig.setup.json):
- agent-jails: JAILS value serialised to JSON string for emitStatus
- environment.test: use import type for pg.Pool type cast
- onboarding: wrap showProfileMenu in normalizePiTuiProfile
- preflight.test: fix process.exit mock type + typed call array casts
- sanoid: execSync → spawnSync for multi-arg zfs invocation
- skills-memory: bracket access for legacy chunking_version field
- upstream: pass process.cwd() to isGitRepo()
- verify: import StripeKeyMode type, annotate stripeKeyMode variable

Full suite: 69 files, 1162 tests passing; tsc --noEmit clean.
