chore: sweep hygiene — dedupe rstest exclude, drop dead Overview, move Codex MCP token note into capability table

[ScriptedAlchemy]

Summary

Three hygiene items from the final sweep (lane B1):

1. examples/rsc-agent-runtime/rstest.config.ts had two exclude: keys in one object literal (TS1117 when type-checked; the second silently won at runtime). Kept exclude: ['tests/route-unit/**'] — the broader form the comment describes — and ordered include before exclude like the root rstest configs.
2. packages/workbench/src/overview-page.tsx exported an Overview component that no production code rendered: main.tsx defines and renders its own Overview (with the extra runtimeDiagnostic prop) and imports only BundleWorkflow and HostAdoptionSection from overview-page.tsx. The only consumer of the exported copy was tests/overview-page.test.ts. Deleted the dead copy and its now-unused imports/helpers (useState, Diagnostic, ProjectClient, overviewFor, Navigation, Topbar, dateTime, stateLabel, sourceFor). HostAdoptionSection and BundleWorkflow remain exported and shared. The unit test now renders HostAdoptionSection directly with overviewFor(status) — the same wiring main.tsx uses — and asserts the AB7211 gate diagnostic through the model.
3. Codex MCP ${PLUGIN_ROOT} note moved out of the website generator's hardcoded mcpPathTokenNotes map (en + zh) into packages/agent-bundle/src/adapters/capabilities/codex-0.147.0.json as a dated mcp.pathTokenLowering row (state: degraded, fields, reason = the previous note verbatim, 2026-09-03 evidence citing codex.ts and the codex.mcp.token.* diagnostics). website/plugins/generated-reference.ts now reads mcp.pathTokenLowering.reason when a host records no mcp.pathTokens fields; the per-locale map is deleted (the zh page already documents that table content stays in English). Codex adapterRevision bumped 1.11.0 → 1.12.0; tests/adapter-metadata.test.ts pin updated. Changeset: .changeset/codex-mcp-path-token-lowering-row.md (patch).

Evidence

• Item 1: tsc --ignoreConfig --noEmit … rstest.config.ts on the origin/main copy → error TS1117: An object literal cannot have multiple properties with the same name (line 11); on this branch → exit 0. rstest list --config rstest.config.ts collects the identical file set before/after and never lists tests/route-unit/**. pnpm examples:check passes (the rsc-agent-runtime check ran validate, build, typecheck, test, test:routes).
• Item 2: rg -n "Overview\b" packages/workbench/src → definitions at main.tsx:377 (rendered at main.tsx:1488) and overview-page.tsx:114 (exported, imported only by tests/overview-page.test.ts). tsc --project packages/workbench/tsconfig.json (via pnpm typecheck) and pnpm lint clean; overview-page.test.ts passes.
• Item 3: pnpm docs:site:build passes (language parity OK); the rendered note is present in website/doc_build/reference/hosts.html and website/doc_build/zh/reference/hosts.html (1 match each, codex row of "MCP transports and token fields"). adapter-metadata.test.ts and adapter-capability-states.test.ts pass with the new revision.

Test plan

• pnpm typecheck — exit 0
• pnpm lint — 0 errors, 0 warnings (1161 files)
• pnpm test:unit — 3002 passed, 1 failed: native-claude-contract.test.ts :: fails closed when the candidate plugin, exact Skill event, or subscription auth source is absent times out at 5000 ms identically on pristine origin/main in this environment (a real claude binary is on PATH here); unrelated to this PR — CI is authoritative.
• pnpm test:projection — 145 passed
• pnpm examples:check — exit 0
• pnpm docs:site:build — exit 0

Review status

• CI: all required checks green on 769a61f50d991607d4e2afed8fb2d916ee1a5e2c.
• chatgpt-codex-connector: quota exhausted — replied "You have reached your Codex usage limits for code reviews" to both the automatic trigger (2026-09-03T16:51:07Z) and the explicit @codex review request (2026-09-03T16:51:53Z). No review threads exist.
• Last codex-reviewed SHA: none.
• Unreviewed SHAs: 656361ffe20c1f41859a0ebc978d75dac5af5039 (initial sweep commit) and 769a61f50d991607d4e2afed8fb2d916ee1a5e2c (changeset PR-number fix, head). Merging on CI green per lane rules; a follow-up review can target the squash commit on main.
