feat(audit): posture-audit subcommand using chant audit engine - #1

Conversation
Adds `github-warden audit` — a DETECT-AND-REPORT command that runs chant's full audit pipeline (fetchRepoFiles → classifyFiles → auditFiles → buildReportModel) over all repos declared in the governance config. The warden App installation token is used for fetching, giving it access to private repos that public-only audit tools cannot reach. - Promotes @intentius/chant and all audit-lexicon packages to runtime deps - src/audit/engine.ts: lazy-loaded pipeline (no top-level chant .ts imports), DETECTORS + CHECKS mirroring blacklight, auditRepos() with concurrency - src/audit/summary.ts: renderPostureSummary + shouldFail (--fail-on semantics) - src/cli.ts: audit subcommand, parseAuditArgs, runAudit, printAuditUsage; exit 4 when findings exceed --fail-on threshold - src/audit/engine.test.ts: 21 tests covering pipeline, shouldFail, summary rendering, token pass-through, and parseAuditArgs
Narrow the posture audit to GitHub posture only. warden governs GitHub, so multi-domain IaC auditing (aws/azure/k8s/docker/gcp/helm/gitlab/forgejo) belongs to the separate blacklight app. The engine now wires only the github CI lexicon (path-detected .github/workflows/*, github postSynthChecks). Drop the 8 non-github lexicon dependencies; keep @intentius/chant and @intentius/chant-lexicon-github. Bundle the CLI with esbuild so chant's .ts source is transpiled and inlined at build time. This fixes ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING when running dist/cli.js under plain Node. chant packages export .ts by default, which only worked under vitest's transpiler. Convert the engine's dynamic chant imports to static top-level imports so esbuild inlines them.
