feat(install): add graphify vibe install for Mistral Vibe CLI

 - Fix: a PHP `use` import written with a leading-backslash / fully-qualified prefix now resolves to its target definition instead of being dropped (#2661, thanks @ousamabenyounes).
 - Fix: an unresolved local JS/TS import (to a file absent from the scan) now emits a stable, portable `ref` target id instead of leaking a per-checkout absolute-path slug (#2457, thanks @rohit-jsfreaky).
 - Fix: `graphify benchmark` no longer crashes on a node whose label is `None` (#2674, thanks @Arthuro0103).
+- Feat: `graphify vibe install` adds full-parity Mistral Vibe (mistralai/mistral-vibe) support — skill file with `user-invocable: true` frontmatter (exposes `/graphify` as a native slash command in vibe's autocomplete), `AGENTS.md` always-on section, and two `pre_tool` hooks in `.vibe/hooks.toml` (matchers `grep` and `read_file` — vibe's snake-cased tool names per `vibe/core/tools/base.py:get_name`) that nudge toward `graphify query` for search/read operations. Global scope honors `VIBE_HOME`, hook ownership is `name`-based (never touches user-authored hooks that happen to shell out to graphify), and `hooks.toml` merges preserve hand-authored comments via `tomlkit`. Verified end-to-end against vibe 2.24.0.
+- Fix: `graphify vibe install` now also writes a writable `graphify-extract` subagent to `<scope>/agents/graphify-extract.toml` and the skill fragment dispatches Task calls with `subagent_type="graphify-extract"` (#2537 review, thanks @MusicalNinjaDad). Vibe's built-in `explore` subagent (`vibe/core/agents/models.py:EXPLORE`) is read-only — its `enabled_tools = ["grep", "read_file", "skill"]` cannot write chunk JSON — so semantic extraction inheriting it silently produced zero `.graphify_chunk_NN.json` files and the pipeline aborted. The new agent enables `write_file` scoped to `**/graphify-out/.graphify_chunk_*.json` only (no unbounded write grant), reuses the `explore` system prompt, and is registered/unregistered by `_install_vibe_extract_agent` / `_uninstall_vibe_extract_agent` symmetric to the hook flow. `uninstall_all` sweeps it alongside the rest.

 Codex users also need `multi_agent = true` under `[features]` in `~/.codex/config.toml` for parallel extraction. CodeBuddy uses the same Agent tool and PreToolUse hook mechanism as Claude Code. Factory Droid uses the `Task` tool for parallel subagent dispatch. OpenClaw and Aider use sequential extraction (parallel agent support is still early on those platforms). Trae uses the Agent tool for parallel subagent dispatch and does **not** support `PreToolUse` hooks, so AGENTS.md is the always-on mechanism.
