feat(vim): added escape/CR literal parsing and count-aware G/gg motions

- Fixed `G`/`gg` motions to distinguish "no count" (go to last/first line) from explicit count.
- Added parsing for literal `\x1b`/`\r` bytes and backslash escape sequences (`\r`, `\e`, `\n`, `\t`).
- Updated `#readCount` to return `hasCount` flag propagated through operator and motion resolution.
- Synced vim buffer fingerprint from disk on reuse to handle LSP writethrough reformats.

 - **Full output access**: Read complete subagent output via `agent://<id>` resources when previews truncate
 - **Isolation backends**: `isolated: true` runs tasks in git worktrees, Unix fuse-overlay filesystems, or Windows ProjFS (`fuse-projfs`), with patch or branch merge strategies
