docs(todo): clarify cross cd refactor task with detailed requirements

- Expand P2 cross cd task with complete issue description
- Document current incorrect behavior (targets worktree, should target local_path)
- Add desired behavior: fzf selection when no args, output path only
- Remove duplicate entry from P3 section
- Mark as HIGH impact (fixes incorrect behavior)
- Reference wt command as working example to reuse

 ### P2: Lower Priority
-- [ ] **Refactor `cross cd`** - Target local patched folder and output path (no subshell), supporting fzf. Enable pattern: `cd $(cross cd <patch>)`
+- [ ] **Refactor `cross cd`** - Target local patched folder (not worktree) and output path (no subshell), supporting fzf
+  - **Issue:** Currently `cross cd` changes to WORKTREE directory (`.git/cross/worktrees/`), which is incorrect
+  - **Desired Behavior:**
+    - `cross cd [path]` → changes to LOCAL_PATH (the actual patched directory in main repo)
+    - `cross cd` (no args) → uses fzf to list and select from local_paths (same as `wt` command implementation)
+    - Output path only (no subshell) → Enable pattern: `cd $(cross cd <patch>)`
+  - **Current Implementation:**
+    - Justfile (lines 761-797): Opens shell in worktree directory (WRONG)
+    - Go (lines 681-730): Opens shell in worktree directory (WRONG)
+    - Rust: Same behavior (WRONG)
+    - `wt` command: Already has fzf selection working correctly - can reuse this pattern
+  - **Required Changes:**
+    - Change target from worktree_path to local_path
+    - Add fzf selection when no path provided (reuse from `wt` command)
+    - Output path string instead of opening subshell
   - **Effort:** 2-3 hours
+  - **Files:** `Justfile.cross`, `src-go/main.go`, `src-rust/src/main.rs`, `test/017_cd_refactor.sh`
+  - **Impact:** HIGH - Fixes incorrect behavior, improves UX significantly
+  - **Status:** Not yet implemented - current behavior is incorrect
 
 - [ ] **Single file patch capability** - Review and propose implementation (tool and test) to be able to patch even single file. If not easily possible without major refactoring, evaluate new command "patch-file".
   - **Effort:** 4-6 hours (includes research)

-- [ ] **Add `cross cd` to local_path capability** - Currently only changes to worktree
-  - **Issue:** `cross cd` currently opens a shell in the WORKTREE (hidden `.git/cross/worktrees/`)
-  - **Desired Behavior:**
-    - Provide ability to change directory to LOCAL_PATH (the actual patched directory in main repo)
-    - Options:
-      1. Add `--local` flag: `cross cd --local [patch]` → changes to local_path
-      2. Add separate command: `cross path [patch]` → outputs local_path for use with shell `cd $(cross path patch)`
-      3. Make `cd` default to local_path, add `--worktree` flag for old behavior
-  - **Current Implementation:**
-    - Justfile (lines 761-797): `cd` target opens shell in worktree directory
-    - Go (lines 681-730): Same behavior - opens shell in worktree
-    - Rust: Similar behavior
-  - **Effort:** 2-3 hours
-  - **Files:** `Justfile.cross`, `src-go/main.go`, `src-rust/src/main.rs`, `test/017_cd_local.sh`
-  - **Complexity:** LOW - Just need to add path resolution and output logic
-  - **Impact:** MEDIUM - Improves workflow for users editing patched files
-  - **Priority Rationale:** Low priority - workaround exists (manually navigate to patch), but UX improvement
-  - **Status:** Not yet implemented, documented for future consideration
