Added actions for every @command.

[robgruen]

This pull request implements full natural-language action coverage for every bundled TypeAgent @ command, with a particular focus on the browser agent's automation commands. It introduces new action schemas and handlers for browser automation, integrates them into the browser agent, and documents the plan and status of this coverage milestone. The most important changes are grouped below:

Browser Agent: Automation Actions Integration

• Added new action schema (BrowserAutomationActions) and handler (executeBrowserAutomationAction) for browser automation commands, supporting launching hidden/standalone automation browsers and closing them. These actions are now fully integrated and invoked via natural-language requests, ensuring parity with their command equivalents. [1] [2] [3] [4] [5] [6]
• Linked the OpenStandaloneAutomationBrowserHandler command to the new automation action, ensuring that both command and action paths share the same implementation and side effects.

Documentation: Coverage Plan and Status

• Added a comprehensive plan (PLAN.md) detailing the requirements, implementation rules, and phases for achieving natural-language action coverage for all TypeAgent commands.
• Added a status tracker (STATUS.md) that reports strict endpoint coverage, current progress, and documents the completion of all agent-host and system command families.

SDK/Helpers: Type and Export Improvements

• Exported the CommandHandlerTypes type and the getCommandHandler function from the command helpers, improving type safety and reusability across the codebase. [1] [2]

Browser Agent: User Experience Enhancement

• Enhanced the WebFlow action result: after successfully starting a goal-driven task, the user is prompted with a clear call-to-action to save the trace as a reusable macro, improving discoverability of automation features.

These changes collectively ensure that every executable TypeAgent command is now accessible via a behaviorally equivalent natural-language action, with strict parity and comprehensive test coverage.
