feat(pi-overflow): 新增统一的新工具结果展示截断扩展

此前截断分散在多层且互相冲突：Pi bash 保留尾部 50KB，RTK 兜底截断又只留
开头 12000 字符（砍掉报错与完整输出路径），pi-chrome 截开头 30K，web_fetch
各 provider 不一致。新扩展统一负责"新结果给模型看多少"：
- capture.ts 最先加载暂存原文，index.ts 最后加载（system-prompt 之前）
- 超过 24K 字符时原文落盘 <agentDir>/my-pi/pi-overflow/（700/600、原子写），
  优先取 bash fullOutputPath 完整文件；模型看到 头 + 中段信号行 + 尾 的有界
  视图，行号基于落盘原文、结尾永远可见
- overflow_query：按 id 正则搜索、行区间、jsonPath 只读查询，id 校验防穿越
- 收编：RTK truncate 默认关闭、删除 pi-chrome truncateText、web_fetch 默认
  每页 20000（上限 100000）、web_search max_results 限定 1–20
- pi-compaction 遮蔽带 details.overflow.id 的结果时在占位符提示 overflow_query
- 登记 tools.jsonc / routing / 权限 allow / tool-search 常驻与分组

 - Added checked-in authoritative groups for every tool exposed by the standard my-pi bundle, eliminating first-use model generation and user caching unless unrecognized third-party tools are present.
 - Replaced the Hermes and third-party Hippo assignments with the five tools exposed by the official Hippo Pi extension, grouped into recall and management workflows.
 - Replaced the retired Hippo `hippo_*` assignments with the vendored Hermes memory extension's six tools, grouped into `memory-recall` (`memory_search`, `session_search`, `context_tree_query`) and `memory-management` (`memory_add`, `memory_replace`, `memory_remove`, `skill_manage`).
+- Added `overflow_query` to `memory-recall` and pinned it in `alwaysEnabled` — inspecting a pi-overflow-stored original must not depend on a `tool_search` activation.
 - Added the enabled bundle's `Agent`, `get_subagent_result`, and `steer_subagent` tools to a checked-in `subagents` orchestration group.
 - Added authoritative `ssh-connection`, `ssh-remote-files`, `ssh-remote-search`, and `ssh-remote-shell` groups for the maintained `pi-ssh` tools, keeping reviewed connection, bounded discovery, structured file operations, and reviewed shell execution separate; the connection workflow now requires sequential `ssh_connect` to succeed before dependent tools.
 - Added sequential `ssh_cd` to the authoritative remote-shell workflow and direct the model to wait for a successful workspace change before dependent remote calls, avoiding both the unknown-tools fallback and cwd races.

 9. Natural-language lookup gives exact tool names and workflow aliases more weight than descriptive overlap. Weak or closely tied matches return candidates without activation.

-The standard bundle assigns the Hermes memory extension's six tools to recall and management groups: `memory_search` and `session_search` join `context_tree_query` in `memory-recall`, while `memory_add`, `memory_replace`, `memory_remove`, and `skill_manage` form `memory-management`. All six are pinned by default, because the injected `<memory-policy>` tells the model to consult and write memory during normal work, and a schema the model cannot see would silently disable that loop. Third-party `tff-memory_*` names and the retired Hippo `hippo_*` names are not seeded. It also assigns `Agent`, `get_subagent_result`, and `steer_subagent` to the `subagents` orchestration group.

 The maintained `pi-ssh` tools are also split by workflow: sequential reviewed agent-controlled connection lives in `ssh-connection`, structured `ssh_read`/`ssh_write`/`ssh_edit` file operations live in `ssh-remote-files`, bounded `ssh_find`/`ssh_grep` discovery lives in `ssh-remote-search`, and sequential reviewed workspace changes plus reviewed command execution live in `ssh-remote-shell`. The workflows tell the model to call `ssh_connect` or `ssh_cd` separately and wait for success before issuing remote calls that depend on the new connection or cwd.
 The maintained `ask_user_question` tool has its own `user-interaction` group so the model can load the complete interactive schema only when a missing decision or preference must come from the user.
 The pinned `pi-chrome` bridge registers its 21 `chrome_*` tools only after explicit per-session authorization. Once registered, catalog refresh assigns them to `chrome-navigation`, `chrome-interaction`, and `chrome-debugging`; the 28-tool default allows all three groups to coexist. Revocation remains enforced inside every upstream tool execution even if a schema is later reactivated by Tool Search.
