 *     in every project) or `./.mcp.json` (local = project scope, the
 *     file Claude Code actually reads for a single project). See the
 *     scope table at https://code.claude.com/docs/en/mcp.
 *   - Permissions to `~/.claude/settings.json` (global) or
 *     `./.claude/settings.json` (local), gated on `autoAllow`.
 *   - Instructions to `~/.claude/CLAUDE.md` (global) or
 *     `./.claude/CLAUDE.md` (local).
 *
 * Earlier versions wrote the local MCP entry to `./.claude.json` — a
 * file Claude Code never reads — so the server silently never loaded
 * until the user manually renamed it to `.mcp.json` (issue #207). We
 * now write `./.mcp.json` and migrate any stale `./.claude.json` entry
 * out of the way on install and uninstall.

 * a matcher group (or the Stop event) with ours survives. We prune a
 * matcher group only once its `hooks` array is empty, an event only
 * once it has no groups left, and `hooks` itself only once every event
 * is gone — and none of that runs unless we actually removed a
 * codegraph command, so a settings.json with no legacy hooks is left
 * byte-for-byte untouched and reported `unchanged`.
 *
 * Exported so it can be unit-tested directly and reused by both
 * `install` (an upgrade self-heals) and `uninstall`.
