fix(omo-codex): bundle explorer/librarian/plan agent TOMLs for spawn_agent

The synced Codex skills (refactor, review-work, remove-ai-slops) emit
`spawn_agent(agent_type="explorer"/"librarian"/"plan", ...)` guidance
that sync-skills.mjs injects into every skill containing OpenCode-only
orchestration calls. Only codex-ultrawork-reviewer.toml was bundled, so
Codex had no matching agent role to dispatch.

An older omo-codex release shipped explorer/librarian/plan TOMLs but
without the required top-level `name` field, leaving Codex to warn:

  Ignoring malformed agent role definition: agent role file at
  ~/.codex/agents/<name>.toml must define a non-empty `name`

This commit bundles three correctly-formed TOMLs into
components/ultrawork/agents/. Each has the full schema Codex parses:
`name`, `description`, `nickname_candidates`, `model`,
`model_reasoning_effort`, `service_tier`, `developer_instructions`.
The existing sync-agents.py SessionStart hook installs them via rglob
into CODEX_HOME/agents/.

Models match the original design: explorer + librarian on gpt-5.4-mini
low effort (fast contextual + external research); plan on gpt-5.5
xhigh effort (deep reasoning + interview-style planning).

Tests:
- test/bundled-agents.test.mjs: locks the sync-hook contract by
  running sync-agents.py against a temp CODEX_HOME and verifying each
  TOML lands with the expected name + schema.
- test/aggregate.test.mjs: locks the schema keys on every bundled
  TOML and the spawn_agent contract (every in-scope agent_type
  referenced by a synced skill has a matching bundle).

Follow-up: the sync-skills.mjs compatibility table also references
`spawn_agent(agent_type="worker", ...)`. No worker.toml is present
in CODEX_HOME and Codex does not warn about its absence, suggesting
worker is a built-in Codex role. Confirm and ship worker.toml if not.
