fix(cursor): write repo-relative shim path in project hooks.json

[stefanwalther]

Problem

graft init writes the checkout's absolute path into the committed .cursor/hooks.json:

{
  "command": "node \"/Users/me/code/proj/.cursor/hooks/graft-hooks.cjs\" cursor-post-tool"
}

That path is different on every machine and worktree. In a repo with committed wiring, each fresh init rewrites these lines, so hooks.json shows as modified everywhere. It also breaks pulls: anyone who ran init locally before fetching the wired branch holds entries that collide with the incoming commit, and git aborts the merge.

Fix

Cursor runs project hooks from the repo root, so the command is now repo-relative:

{
  "command": "node .cursor/hooks/graft-hooks.cjs cursor-post-tool"
}

The stale-entry check matches on graft-hooks.cjs, so the next init swaps old absolute entries in place. Nothing to clean up by hand.

Verification

New test assertion that no checkout path leaks into the commands. Full suite green (1221 tests), tsc clean.

Ownership is git history over each area's own files, weighted towards recent work (120-day half-life). Merge commits and bots are dropped, and you are dropped from your own PR. A name with no @ has no GitHub handle in its commit email — tag them by hand, or add a .mailmap entry. A suggestion from history, not a CODEOWNERS rule.

Test signal per changed area — 1 ✓

Reached = a node under a test path has a resolved edge into the changed symbol. It undercounts anything called indirectly — through a CLI, a spawned process or a dynamic import — so read a low ratio as “look here”, never as a coverage gate.
