refactor: 移除 context-mode，Chrome 快照改为直接返回

context-mode 的 ctx_execute 系工具以真实 shell 执行且权限为 allow，绕过了
bash 策略与 protectedWrites；其每轮注入、独立 MCP 子进程与 skills 也与组合包
提示词单一所有权冲突。大输出职责已由 pi-overflow（入口截断）与
pi-compaction（压力遮蔽）承担：
- 删除 context-mode 依赖、wrapper/过滤器、skills，以及 ctx_* 的权限、
  tools.jsonc、路由规则、tool-search 常驻与 4 个分组
- better-sqlite3@12 仅为 context-mode 传递依赖，随之移除根 allowScripts
- pi-chrome：按用户决定移除快照隐私规则与 .pi/chrome-context 临时文件机制，
  快照 JSON 直接作为工具结果返回、details 只留小型元数据，超长由 pi-overflow
  截断并用 overflow_query 提取；授权生命周期不变

 ## Unreleased — my-pi maintained source
 
 ### Changed
+- Removed the retired context-mode integration: the `ctx_execute` / `ctx_execute_file` / `ctx_batch_execute` pins left `alwaysEnabled` and the four `context-*` bundle groups were dropped. Large tool results are now bounded by pi-overflow and recoverable through the pinned `overflow_query`.
 - Imported upstream `v0.3.6` at `ddfb23646fd3957b791214de278e23aa393c9b13` for direct local maintenance.
 - Migrated runtime imports to `@earendil-works/pi-coding-agent` and current `typebox`.
 - Replaced the hidden steer/retry compatibility loop with current Pi dynamic-tool propagation.

-1. `session_start` activates `tool_search`, the six cross-platform Pi core tools, and configured `alwaysEnabled` names. The my-pi defaults also pin CodeGraph exploration, LSP diagnostics, the three high-frequency Context Mode execution tools, and the six Hermes memory tools. On Windows, `powershell` is pinned beside `bash`; on non-Windows hosts it is excluded. Pinned tools do not consume the dynamic-group or dynamic-tool budget.

Pinned tools do not consume the dynamic-group or dynamic-tool budget.
 2. Hidden definitions are hashed with grouping constraints and matched against `extensions/bundle-groups.ts`. Available standard tools receive checked-in groups; unavailable optional tools are omitted.
 3. If every hidden tool is recognized, the bundle catalog is used directly. No model call or per-user cache is required.
 4. Additional tools receive immediate deterministic prefix/source groups. A matching model-enriched cache is reused only if it preserves all checked-in bundle assignments.
