refactor(worker): use --permission-mode auto instead of --dangerously-skip-permissions

Map legacy "bypassPermissions" config to "auto" at dispatch time; pass-through other modes (acceptEdits, plan, default).

 ## Key Components
 
-- **ClaudeProcess** — spawns `claude -p --output-format stream-json --verbose --dangerously-skip-permissions`. Writes prompt to stdin, reads NDJSON from stdout. Supports CancellationToken (kills process tree).
+- **ClaudeProcess** — spawns `claude -p --output-format stream-json --verbose --permission-mode auto` (or whatever permission mode the app settings specify). Writes prompt to stdin, reads NDJSON from stdout. Supports CancellationToken (kills process tree).
 - **ClaudeArgsBuilder** — dynamically constructs CLI args; supports `--model`, `--append-system-prompt`, `--agents`, `--json-schema`, `--resume`
 - **StreamAnalyzer** — parses rich NDJSON output; extracts session_id, token counts, turn counts, result text, structured output. Replaces MessageParser.
 - **TaskResetService** — discards a failed task's worktree and resets the task row to Manual; preserves run history.

 - The worker runs standalone — start it separately from the UI

+- ClaudeProcess uses `--permission-mode auto` by default; legacy "bypassPermissions" settings are mapped to `auto` at dispatch time. `acceptEdits`, `plan`, and `default` pass through unchanged.
 - Worktree branches follow `claudedo/{id}` naming convention
