PR Review: docs: add missing commands to help view

Summary

This PR adds documentation for several command mode commands (:login, :theme, :autosave, :q) that were missing from the help view, and updates the command examples section. The changes are straightforward and improve the discoverability of these features.

Code Quality ✅

• Clean and consistent: The changes follow the existing code structure and formatting patterns
• Proper placement: New command documentation is logically placed in the "Command Mode" section alongside other command-mode keybindings
• Consistent style: Uses the same s.key.Render() and s.desc.Render() pattern as existing entries

Verification ✅

I verified that all documented commands exist in the codebase:

• :q - Implemented at internal/view/command_input.go:223
• :login - Implemented at internal/view/command_input.go:244-258
• :theme - Implemented at internal/view/command_input.go:296-303
• :autosave - Implemented at internal/view/command_input.go:305-313

Observations

Positive aspects:

1. Improves user experience by documenting previously undocumented commands
2. The :login descriptions accurately reflect the implementation (default profile is "claws-login")
3. Command examples section was improved by replacing less useful examples with more practical ones

Minor inconsistencies noted (not blockers):

1. Line 157: Removed the :sort desc Age example - this is fine as it simplifies the examples, but users may want to know about the descending sort option
2. The help view already shows q as a quit key in the Navigation section (line 71), and now :q is also shown - this redundancy is acceptable as they're different methods to quit

Test Coverage ⚠️

The existing test file (internal/view/help_view_test.go) only has basic tests for creating the view and checking the status line. Consider adding a test that verifies all documented commands in the help text actually have corresponding implementations. However, this is not a blocker for this PR since:

• This is a documentation-only change
• All commands were manually verified to exist
• The existing test coverage is minimal throughout

Performance Considerations ✅

• No performance impact - only adds a few string literals to the rendered content

Security Concerns ✅

• No security concerns - purely display/documentation changes

Recommendations

1. ✅ Approve and merge - This is a good documentation improvement
2. 💡 Optional follow-up: Consider documenting the desc option for the :sort command somewhere, since the example was removed
3. 💡 Optional follow-up: Add integration tests that verify help documentation matches actual command implementations to prevent drift

Verdict

LGTM - Ready to merge! 🚀

This is a clean, well-executed documentation improvement that makes the application more user-friendly. The changes are accurate, consistent with the existing codebase, and enhance feature discoverability.
