feat(claude): add permission_mode config option

[nathanschram]

Problem

Claude Code's --permission-mode CLI flag allows overriding the default permission mode (default, plan, acceptEdits, bypassPermissions, etc.). Users may have "defaultMode": "plan" in their global ~/.claude/settings.json for interactive sessions, but this causes Takopi sessions to get permanently stuck — ExitPlanMode requires terminal interaction that can't happen in -p mode.

There's currently no way to configure --permission-mode in takopi.toml for the Claude engine. The runner builds CLI args with --allowedTools and --dangerously-skip-permissions, but not --permission-mode.

Proposed Solution

Add permission_mode as a config option in the [claude] section:

[claude]
allowed_tools = ["Bash", "Read", "Edit", "Write", "Glob", "Grep"]
permission_mode = "acceptEdits"

Implementation (3 lines)

runners/claude.py — ClaudeRunner dataclass:

permission_mode: str | None = None

runners/claude.py — _build_args():

if self.permission_mode is not None:
    args.extend(["--permission-mode", self.permission_mode])

runners/claude.py — build_runner():

permission_mode = config.get("permission_mode")
if permission_mode is not None:
    permission_mode = str(permission_mode)

Then pass it to ClaudeRunner(permission_mode=permission_mode, ...).

Why This Matters

Without this, users who prefer "defaultMode": "plan" for interactive Claude Code sessions have no way to override it for Takopi. The session enters plan mode, calls ExitPlanMode, and blocks forever waiting for terminal approval that can never come.

Setting permission_mode = "acceptEdits" in takopi.toml cleanly separates interactive (plan mode) from non-interactive (accept edits) behavior.

Workaround

I've monkey-patched this locally and confirmed it works — sessions that previously got stuck in plan mode now execute normally. Happy to open a PR if preferred.
