feat+test+docs: D47 — bin/olp-keys.mjs keygen CLI (Phase 2 functional scope closes) (#23)

Fourth Phase 2 implementation D-day. Closes ADR 0007 § 10 acceptance
criterion #9 (bootstrap workflow must be reproducible without manual
file editing) by shipping a minimal keygen CLI per § 9.1. Phase 2
functional scope is complete with this D-day — remaining work is
Phase 2 close → v0.2.0 (maintainer-triggered, explicit per
CLAUDE.md release_kit.phase_close_trigger).

NEW bin/olp-keys.mjs (~250 lines): subcommand CLI

  keygen [--owner|--name=X|--tier=guest|owner|--providers=csv|--force]
    Creates a key + prints plaintext token to stdout ONCE; manifest
    stores only SHA-256 hash. --force revokes existing owner keys
    before creating the new owner (ADR § 9.3 recovery flow).

  list [--owner-only|--include-revoked]
    Lists keys with token_hash redacted.

  revoke --id=<key-id>
    Marks the key's revoked_at; idempotent (already-revoked → no-op
    + status message); missing id → exit 2.

  Common flag: --olp-home=<path> overrides ~/.olp/ (defaults to
  OLP_HOME env then ~/.olp/).

package.json bin field

  "bin": { "olp-keys": "./bin/olp-keys.mjs" } so npx olp-keys ...
  resolves. Also "scripts": { "olp-keys": "node bin/olp-keys.mjs" }
  for npm run.

Module shape (testability)

  Exports runCli(argv, { out, err }) so tests invoke with synthetic
  argv + IO writers (no process spawn). Main guard auto-runs when
  invoked as entrypoint.

Plaintext token discipline (ADR § 5 + § 9.1)

  Plaintext printed exactly once on stdout. Never logged, never
  written to manifest, never written to audit. Operators capture
  immediately; lost → --force revoke + regenerate.

--force async correctness

  cmdKeygen is async and awaits each revokeKey (which is async —
  acquires per-key write lock per § 6.4). Sequence: revoke each
  existing owner manifest atomically → then createKey for new
  owner. Avoids race where create-new runs before revoke-old
  completes.

TESTS — Suite 22, +20 (524 → 544):

  22a-1..5: parseArgv unit (--flag=value, --flag value, boolean,
    mixed positional)
  22b-1..5: keygen (owner default, name+providers, missing-name
    error, invalid-tier error, --force revoke-then-create with
    isolation tmpdir)
  22c-1..3: list (empty, populated with token_hash-redaction check,
    --owner-only filter)
  22d-1..4: revoke (valid id, idempotent re-revoke, missing-id
    error, nonexistent-id error)
  22e-1..3: top-level CLI (--help / no args / unknown subcommand
    exit codes)

DOCUMENTATION:

  - AGENTS.md: lib/keys.mjs marker promoted to ✅; new bin/olp-keys.mjs
    entry. Implementation-status-note + shipped-set updated.
  - README.md: Implementation Status row added for bin/olp-keys.mjs;
    Known limitations note rewritten to "Phase 2 functional scope
    complete; close pending"; new Bootstrap workflow section with
    copy-pasteable npx commands + recovery flow.
  - CHANGELOG.md: D47 entry under Unreleased per release_kit overlay.

AUTHORITY:

  - ADR 0007 — § 5 token format, § 9.1 minimal keygen command
    surface, § 9.3 recovery, § 10 acceptance criterion #9 covered.
  - CLAUDE.md release_kit overlay phase_rolling_mode — under
    Unreleased.
  - Standing autopilot grant.

Verified: 544/544 pass via npm test (no regression in 524 pre-D47
tests; 20 new Suite 22 tests all green).
