feat: cronjobs

[Copilot]

Adds deepwork schedule command to create periodic tasks using native OS schedulers (systemd timers on Linux, launchd agents on macOS).

Implementation

CLI Commands

• deepwork schedule add <task-name> <command> [--interval <interval>] - Creates scheduled task
• deepwork schedule remove <task-name> - Removes scheduled task
• deepwork schedule list - Lists active scheduled tasks

Platform Support

• Systemd: Generates service + timer units in ~/.config/systemd/user/
• Launchd: Generates plist in ~/Library/LaunchAgents/
• Logs to .deepwork/logs/<task-name>.{log,err}

Security

• Task names validated: ^[a-zA-Z0-9_-]+$
• Commands parsed with shlex.split() to handle quoted arguments correctly
• XML special characters escaped in launchd plists
• Shell escaping for systemd service files

Example

# Schedule daily sync
deepwork schedule add sync-daily "deepwork sync" --interval daily

# Schedule with quoted arguments
deepwork schedule add commit 'git commit -m "Automated"' --interval hourly

# Custom interval (seconds)
deepwork schedule add custom "echo test" --interval 3600

Supported Intervals

hourly, daily, weekly, monthly, or integer seconds (launchd) / systemd calendar expressions
