Tianyi Cui c3424e5487 fix(docs): address Codex review round 1 on the AGENTS.md rewrite
- Restore the universal JSDoc rule the rewrite dropped (module doc
  comment + semantic JSDoc on every export), in root AGENTS.md § Type
  safety and documentation — the generated-catalog RFC cites it as the
  rule the generator enforces at the source.
- Repoint the six remaining citations of moved content that the
  section-name grep missed (rule-title quotes and prose references):
  agent-loop agent.ts, acp index.ts, acp turns.spec.ts, the Exa e2e
  header, the real-api-e2e RFC, the doc-sync-enforcement RFC amendment,
  and rfc/implemented/AGENTS.md's section-name casing.
- Fix two docs/testing.md overstatements: the unit tier also runs
  examples/*/tests specs, and keyless-by-nature examples have no
  with-key smoke.
- Displacement trims keep root AGENTS.md at 1,498/1,500.

core/ — product API spine

The packages every harness build is assembled from: the session log, the system-prompt assembly, the tool registry, the agent vocabulary, and the one concrete loop that drives them. These are product packages — the stable surface plugins and consumers build against.

Package Role ctx key
session/ Event-sourced session log + in-memory store ctx.sessions
system-prompt/ Prompt-section + tool-schema assembly registry ctx.systemPrompt
tools/ Tool registry + tools/pre-execute/tools/post-execute pipeline ctx.tools
agent/ Agent interface, registry, agent/* event vocabulary ctx.agents
agent-loop/ The concrete loop plugin: ReactLoopAgent + the loop driver ctx.agentLoop
agent-core/ Bundle plugin: the providerless/executor-less/UI-less spine as code (loads the spine)

agent-loop is the one concrete implementation of the agent seam and lives here because it is the harness's default product loop; everything else in core/ is interface/vocabulary. Plugins depend on the agent vocabulary, never on agent-loop directly, so the loop stays swappable.

agent-core is the composition counterpart: one bundle plugin that loads the whole providerless spine (timer + llm + sessions + system-prompt + tools + agents + invariants + tool-bash + agent-loop) and forwards agent-loop's agents list as its own config. App packages (ui/stdio-agent, ui/acp-agent) consume it and add only a front door; a leaf adds the swappable backends plus any optional product tools it wants to expose. It lives in core/ because it composes exclusively core/ + interface packages and ships no provider, executor, or UI of its own.
