Normalize the chat content rail around the input composer as the width baseline. This introduces shared rail variables, compensates message content for the actual scrollbar gutter, and separates mobile/webview behavior so desktop, mobile web, and app shell layouts stay centered consistently.
Align assistant text, markdown blocks, tables, minimal-mode summaries, expanded minimal steps, slash/runtime/git floating UI, and brief-message separators to the same horizontal rail. Remove the collapsed right resize handle and mobile menu glow while preserving the intended percentage widths for floating composer affordances.

Introduce workspace-level goal state persistence, goal prompt injection, and after-turn review handling so an active task can continue until the configured completion conditions are met.
Add a dedicated goal review agent with readonly and active evidence modes, configurable model settings, review prompt, token/turn boundaries, idle-no-tool protection, and progress/completed/stopped events.
Wire goal_mode through task creation, task restoration, compression handoff, runtime user messages, API message sanitization, and tool-call ordering so goal continuations survive long-running tasks and deep compression.
Add Vue UI for arming goal mode from the quick menu, showing running/completed banners, displaying progress metrics, restoring running goal state, and exposing personalization settings for review mode and stop limits.
Include goal mode research notes and default goal review configuration.
This commit consolidates a large set of host-mode security and UX fixes across backend and frontend.
Security / execution model:
- Make permission/execution mode switches apply immediately (no deferred pending-only behavior).
- Keep runtime mode change notices durable and visible via user-message guidance path.
- Add explicit runtime message source taxonomy support and persistence:
user / presend / guidance / notify / sub_agent / background_command.
- Ensure guidance/notify insertion is batched per tool-cycle so mid-run inserts are committed together.
- Separate notify from guidance semantics for mode-change notices.
- Add direct-mode auto-fallback handling visibility on frontend.
Approval and command gating:
- Align run_command approval pre-check logic with docker behavior for approval/auto_approval modes in host execution paths.
- Keep approval retry flow and final-result semantics intact when permission errors trigger approval.
- Externalize forbidden command keyword list into JSON config:
config/forbidden_commands.json.
- Update forbidden command rejection message to user-facing wording:
用户不允许执行包含“... ”的指令.
Prompt/runtime guidance:
- Refine execution-mode runtime rule text to avoid endless workaround loops:
one safe alternative first, then request switching to direct mode when truly required.
Chat rendering / message UX:
- Prevent injected guidance/notify user-messages from incorrectly triggering assistant work header/timer chain.
- Restore correct visibility after history reload while preserving runtime-source behavior.
- Update user-header icon/label rendering by message source:
- guidance -> 引导 + navigation icon
- notify/sub_agent/background_command -> 通知 + bell icon
- user/presend -> keep normal user header.
- Add new icons: static/icons/navigation.svg, static/icons/bell.svg.
Approval panel UX:
- Convert desktop approval panel from layout-compress sidebar to overlay + blur sheet.
- Fix panel transition behavior (remove unintended vertical motion; use dedicated desktop overlay transition).
- Improve approval result display:
- decision and reason split lines,
- green/red status styling,
- multiline reason rendering,
- auto-collapse delay adjusted to 3s.
Execution mode TTL feedback:
- When direct mode auto-expires to sandbox, frontend menu state is updated from status snapshot.
- Show non-auto-dismiss warning toast to explicitly notify auto-fallback.
Misc consistency updates:
- Execution mode label text cleanup in composer.
- Runtime notice wording normalization (权限模式修改为..., 执行环境修改为...).
Build/test notes:
- Frontend rebuilt after UI changes.
- Smoke tests passed for server refactor path.
