#14100: fix(linux): add gio and trash-put fallbacks for moveToTrash

#### Summary On minimal Linux installs, `trash-cli` is often not installed, causing `moveToTrash()` to silently fail. This leaves files in place with only a log message during `openclaw reset` and agent deletion. Fixes #14081 #### Root Cause Both trash implementations only try the `trash` command. If it fails: - `onboard-helpers.ts:moveToTrash` — logs failure and continues (files left in place) - `browser/trash.ts:movePathToTrash` — falls back to `~/.Trash` rename (better, but still only tries `trash`) However, `gio trash` (from GLib, available on most desktop Linux) and `trash-put` (alternative trash-cli name) are commonly available alternatives. #### Changes **`src/commands/onboard-helpers.ts`** - `moveToTrash()` now tries three commands in order: `trash` → `gio trash` → `trash-put` - Returns on first success; only logs failure if all three fail **`src/browser/trash.ts`** - `movePathToTrash()` now tries the same three commands before falling back to `~/.Trash` rename #### Tests 5 new tests in `onboard-helpers.test.ts`: ``` ✓ src/commands/onboard-helpers.test.ts (14 tests) 10ms ``` - First command succeeds - Fallback to `gio trash` - Fallback to `trash-put` - All commands fail → logs failure - Skips non-existent paths lobster-biscuit **Sign-Off** - Models used: Claude Opus 4 - Submitter effort: AI-assisted, verified both trash code paths - Agent notes: Simple but impactful — fixes silent failures on minimal Linux installs <!-- greptile_comment --> <h2>Greptile Overview</h2> <h3>Greptile Summary</h3> Added fallback support for `gio trash` and `trash-put` commands when `trash` is unavailable on minimal Linux installations. - Both `moveToTrash()` and `movePathToTrash()` now try three commands sequentially: `trash` → `gio trash` → `trash-put` - Prevents silent failures during `openclaw reset` and agent deletion when trash-cli is not installed - Comprehensive test coverage with 5 new tests covering all fallback scenarios <h3>Confidence Score: 5/5</h3> - This PR is safe to merge with minimal risk - The changes are well-implemented with proper fallback logic, comprehensive test coverage (5 new tests covering all code paths), and follow existing code patterns. The implementation is defensive, maintains backward compatibility, and solves a real issue on minimal Linux installations without introducing side effects - No files require special attention <!-- greptile_other_comments_section --> <!-- /greptile_comment -->
