fix(cli): task-setup uses --path-format=absolute for git-common-dir

[buremba]

Summary

Follow-up to #899. The previous fix called git rev-parse --git-common-dir without forcing absolute output. From inside a checkout, git returns a path relative to its cwd (../.git), and dirname of that resolves against whatever directory the caller happens to be in. Net result:

cd ~/Code/lobu                    # main repo
make task-setup NAME=foo
# resolves repo to /Users/burakemre/Code   ← parent of lobu, wrong!
# worktree created at /Users/burakemre/Code/.claude/worktrees/foo

Fix

Pass --path-format=absolute so git always returns the full path (e.g. /Users/burakemre/Code/lobu/.git). dirname of an absolute path is invariant to cwd.

-repo="$(cd "$(dirname "$(git -C "$script_dir" rev-parse --git-common-dir)")" && pwd)"
+repo="$(dirname "$(git -C "$script_dir" rev-parse --path-format=absolute --git-common-dir)")"

Verification

from main:      /Users/burakemre/Code/lobu  ✓
from worktree:  /Users/burakemre/Code/lobu  ✓

Caught while validating #899 — same logic but two cwds wrong.

📝 Walkthrough

Walkthrough

The script now resolves the repo path using git rev-parse --path-format=absolute --git-common-dir followed by dirname, replacing the previous cd ... && pwd approach. This ensures the computed worktree target path resolution is independent of the caller's current working directory, preventing nested or incorrect worktree placement when invoked from within an existing worktree.

Changes

Worktree Path Resolution

Layer / File(s)	Summary
Repo path resolution using git rev-parse scripts/task-setup.sh	The repo path calculation is changed from a relative cd ... && pwd method to an absolute git rev-parse --path-format=absolute --git-common-dir approach, making it invariant to the caller's current worktree context.
