feat: implement CLI v2.1.81 features and global CLAUDE.md editor

- #248: add output_style field to System init message (forward-compat)
- #245: add fast_mode_state field to Result message (forward-compat)
- #246: add model_usage field to Result message with per-model logging
- #247: add total_cost_usd field to Result message (authoritative cost)
- #237: add bare_mode config option (passes --bare flag to Claude Code)
- #239: add show_clear_context_on_plan_accept config option (settings JSON)
- #244: add custom_model_option config option (ANTHROPIC_CUSTOM_MODEL_OPTION env)
- #262: add global CLAUDE.md editor to config sidebar (get/save_global_claude_md commands)
- fix: wire disable_cron and disable_skill_shell_execution into all start_claude invocations
- fix: wire all new config fields into all start_claude invocations
