feat(agent): light/balanced/delivery role settings with unified tools / 角色设定与统一工具面

Problem:
Work modes (economy/full/delivery) mixed token surface trimming, delivery
gates, and UI labels. Economy forced connect_tool_source schema growth;
switching modes rebuilt controllers and busted prompt-cache prefixes.
Skill profiles could hide tools from the model surface.

Fix:
- Introduce AgentPreset (light|balanced|delivery) + TaskPolicy host floors
  for plan route, verification, and independent review.
- Share one provider-visible core surface across presets; optional tools
  dispatch only through use_capability (retire connect_tool_source boot).
- Switch role settings in place without controller rebuild (CLI /preset,
  desktop, ACP agent_preset; legacy work_mode/tokenMode dual-write one version).
- Emit turn_phase and completion_summary events; wire desktop/CLI UI.
- Keep skill profiles diagnostic-only; dual-write agent_preset on tabs/branch meta.
- Docs, i18n, golden surfaces, and regression matrix updated.

Verification:
- go test ./internal/boot ./internal/agent ./internal/cli ./internal/acp
  ./internal/control ./internal/skill ./internal/agentpreset ./internal/taskpolicy
- desktop role-setting smoke tests

+Choose the startup role setting with
+`--preset light|balanced|delivery` (for example, `reasonix run --preset
+delivery "fix and verify this bug"`). Legacy `--profile economy|balanced|delivery`
+still works (`economy` maps to `light`). All three role settings share the same
+provider-visible core tool surface: direct read/bash/edit/write, background-shell
+lifecycle tools, `ask`/`compress` when registered, and the stable
+`use_capability` proxy for optional tools (search, MCP, skills, subagents, docs,
+web_fetch, and so on). Calling `use_capability` never expands the top-level
+provider schema, so the prompt-cache tool prefix stays stable across role
+settings.
 
-Desktop tabs expose the same three choices and persist Economy or Delivery;
-legacy empty/`full` values remain Balanced.
+What differs by role setting is host policy (planning route, verification
+intensity, independent review floor), not the tool list:
+
+- **Light** — direct-first planning, targeted verification, independent review only
+  on high-risk/security class work; optional capabilities stay on-demand.
+- **Balanced** (default) — auto light/full planning by risk, risk-tiered
+  verification, conditional independent review on medium-risk multi-file work.
+- **Delivery** — full acceptance criteria, full verification, forced independent
+  review on medium+ risk, and security review on high-risk work. Mutations and
+  verification commands are blocked until a concrete acceptance list exists; a
+  changed result cannot finalize until it has been reviewed, verified after the
+  latest mutation, and signed off with `complete_step`.
+
+Meta tools such as `task`, `run_skill`, and `review` are not counted as mutations
+by themselves — only real child writes are. Read-only analysis remains available
+without forcing a write.
+
+Inside an interactive TUI session, use `/preset` to inspect the current choice or
+`/preset light|balanced|delivery` to switch it. `/work-mode` and `/profile` are
+compatibility aliases. The switch updates the role setting in place without
+rebuilding the controller, preserves history, the session path, leases, and the
+Ask/Auto/YOLO posture, and is rejected while a turn, approval/question, background
+job, or another runtime switch is active. This command changes only the current
+session and does not persist a new global default. Because the provider-visible
+tool surface is unified, switching role settings does not create a new tool-schema
+cache prefix.
+
+Desktop tabs expose the same three choices (shown as Light / Balanced / Delivery)
+and dual-write `agentPreset` with legacy `tokenMode` (`economy`/`full`/`delivery`)
+for one compatibility version.
