Make plan approval gate non-destructive and baseline-aware

- Remove all file revert/delete logic from check_plan_approval_gate:
  no more git checkout or fs::remove_file calls. The gate only warns.
- Remove reverted_files field from ApprovalGateResult::Blocked.
- Add get_dirty_files() helper to snapshot dirty files as a HashSet.
- Capture baseline dirty files when plan mode starts (set_plan_mode).
  Pre-existing dirty files are excluded from gate checks so they
  never trigger blocking.
- Add 5 new unit tests covering non-destructive behavior, baseline
  exclusion, and mixed baseline/new file scenarios.
- Update integration test to match new non-destructive semantics.

### Plan Approval Gate (Non-Destructive + Baseline-Aware)
- `crates/g3-core/src/tools/plan.rs` [973..983] - `ApprovalGateResult` enum: `Allowed`, `Blocked { message }`, `NotGitRepo` — no `reverted_files` field
- `crates/g3-core/src/tools/plan.rs` [985..1003] - `get_dirty_files()` - returns `HashSet<String>` of dirty file paths from `git status --porcelain`
- `crates/g3-core/src/tools/plan.rs` [1005..1098] - `check_plan_approval_gate(session_id, working_dir, baseline_dirty)` - warn-only, never reverts/deletes files, excludes baseline dirty files

- `crates/g3-core/src/lib.rs` [1675..1686] - `set_plan_mode(enabled, working_dir)` - captures baseline on enable, clears on disable
- **Key invariant**: The approval gate NEVER deletes or reverts files. It only warns.
- **Key invariant**: Pre-existing dirty files (captured at plan mode start) are excluded from gate checks.
