refactor: Refactor A2A task display and configuration handling

[edenreich]

Improves how A2A tasks are shown in the UI by removing redundant Task field from results and adding proper formatting. Adds config directory support for artifact downloads and includes a new browser agent configuration. Also fixes autocomplete shortcut detection and updates all documentation to reflect the new subcommand-based shortcut structure.

Changes:

Code Changes

1. Added new browser-agent configuration in .infer/agents.yaml
2. Refactored config directory handling with configDir field and getter/setter methods
3. Changed default download artifacts directory from /tmp/downloads to config-relative path
4. Removed Task field from A2ASubmitTaskResult in multiple places
5. Added new formatA2ATaskData method for cleaner task display
6. Updated UI preview formatting for A2A tasks and tool calls
7. Fixed autocomplete shortcut detection logic

Shortcut Structure Changes

8. Migrated shortcuts to subcommand structure:
   • Git shortcuts: /git-status → /git status, /git-commit → /git commit, etc.
   • SCM shortcuts: /scm-issues → /scm issues, /scm-pr-create → /scm pr-create, etc.
   • A2A shortcuts: /agents-add → /agents add, /agents-remove → /agents remove, etc.
   • MCP shortcuts: /mcp-add → /mcp add, /mcp-enable → /mcp enable, etc.

Documentation Updates

   • Added subcommand explanation with examples
   • Updated all shortcut references to new format
   • Added example YAML for shortcuts with subcommands

• Organized shortcut structure with subcommands for better UX
• Consistent documentation across all files
• Clearer artifact download workflow using WebFetch

TODOs

• Check how to enforce the LLM to download artifacts to the correct directory - probably I need to check the system prompt if it has the correct instructions and ensure the command is working as intended
• Make the A2A_DownloadArtifacts tool more reliable - I've noticed that it cannot find the task after completion and it fails then the LLM downloads the artifacts using standard curl, expected is that the LLM uses only the A2A_DownloadArtifacts tool - which will first fetch the task, and get the download link from the task so it can download Remove A2A_DownloadArtifacts - it's redundant, improve WebFetch instead
• Add docs
