Add container-native scheduled task system with timezone support

Introduces a cron-based scheduler that lets Claude set up recurring and
one-time tasks inside containers. Tasks run as separate Claude Code agents
and persist across container recreation via the named volume.

New files:
- container/triple-c-scheduler: CLI for add/remove/enable/disable/list/logs/run/notifications
- container/triple-c-task-runner: cron wrapper with flock, logging, notifications, auto-cleanup

Key changes:
- Dockerfile: add cron package and COPY both scripts
- entrypoint.sh: timezone setup, cron daemon, crontab restore, env saving
- container.rs: init=true for zombie reaping, TZ env, scheduler instructions, timezone recreation check
- image.rs: embed scheduler scripts in build context
- app_settings.rs + types.ts: timezone field
- settings_commands.rs: detect_host_timezone via iana-time-zone crate
- SettingsPanel.tsx: timezone input with auto-detection

+const SCHEDULER_INSTRUCTIONS: &str = r#"## Scheduled Tasks
+
+This container supports scheduled tasks via `triple-c-scheduler`. You can set up recurring or one-time tasks that run as separate Claude Code agents.
+
+### Commands
+- `triple-c-scheduler add --name "NAME" --schedule "CRON" --prompt "TASK"` — Add a recurring task
+- `triple-c-scheduler add --name "NAME" --at "YYYY-MM-DD HH:MM" --prompt "TASK"` — Add a one-time task
+- `triple-c-scheduler list` — List all scheduled tasks
+- `triple-c-scheduler remove --id ID` — Remove a task
+- `triple-c-scheduler enable --id ID` / `triple-c-scheduler disable --id ID` — Toggle tasks
+- `triple-c-scheduler logs [--id ID] [--tail N]` — View execution logs
+- `triple-c-scheduler run --id ID` — Manually trigger a task immediately
+- `triple-c-scheduler notifications [--clear]` — View or clear completion notifications
+
+### Cron format
+Standard 5-field cron: `minute hour day-of-month month day-of-week`
+Examples: `*/30 * * * *` (every 30 min), `0 9 * * 1-5` (9am weekdays), `0 */2 * * *` (every 2 hours)
+
+### One-time tasks
+Use `--at "YYYY-MM-DD HH:MM"` instead of `--schedule`. The task automatically removes itself after execution.
+
+### Working directory
+Use `--working-dir /workspace/project` to set where the task runs (default: /workspace).
+
+### Checking results
+After tasks run, check notifications with `triple-c-scheduler notifications` and detailed output with `triple-c-scheduler logs`.
+
+### Timezone
+Scheduled times use the container's configured timezone (check with `date`). If no timezone is configured, UTC is used."#;
