chore: resolve post-edit hook path via CLAUDE_PROJECT_DIR

[rahmanunver]

The PostToolUse hook command was a repo-root-relative path, so it only resolved when the shell's working directory happened to be the repo root.

Widget work follows docs/widget-scripts.md and runs from inside the package directory, where that path does not exist. The hook fails non-blocking, so the auto-format silently stops running and the loss is easy to miss.

$CLAUDE_PROJECT_DIR is set to the project root, so the path resolves regardless of working directory. Behaviour at the repo root is unchanged.

⚠️ Low — Double-quoting may break hook invocation depending on runner behaviour

File: .claude/settings.json line 51
Problem: The new command value is "\"$CLAUDE_PROJECT_DIR/.claude/hooks/post-edit.sh\"" — after JSON parsing, the string Claude Code actually receives is "$CLAUDE_PROJECT_DIR/.claude/hooks/post-edit.sh" (with literal surrounding double-quote characters as part of the string). If the hook runner passes this to sh -c, the shell will strip the quotes and expand the variable correctly. However, if the runner executes it as a raw argv[0] (i.e. execve without a shell), the leading " will be treated as part of the filename and the hook will silently fail — the exact same silent-failure mode the PR is trying to fix.

The safer and more idiomatic form, which works regardless of how the runner invokes commands, is without the embedded quotes:

Fix:

"command": "$CLAUDE_PROJECT_DIR/.claude/hooks/post-edit.sh"

If the variable alone is not expanded by the runner, the next safest form wraps the whole thing in an explicit shell invocation:

"command": "bash -c '$CLAUDE_PROJECT_DIR/.claude/hooks/post-edit.sh'"

Recommend verifying with pnpm start from inside a widget package (e.g. packages/pluggableWidgets/combobox-web) to confirm formatting fires after an edit.

Positives

• Root cause is correctly identified and explained in the PR description — the relative path only resolves when CWD is the repo root, which breaks all widget-level work.
• The fix is surgical: one line, no unrelated changes.
• $CLAUDE_PROJECT_DIR is the right variable to use; it's documented as pointing to the project root regardless of working directory.
