feat(palette): comprehensive command library (32 commands, up from 11)

Added commands focused on ergonomics and mouse-free operation:

View (window toggles, 12 new): toggle_text_viewer, toggle_diagnostics, toggle_usage_analytics, toggle_context_preview, toggle_tier1_strategy, toggle_tier2_tech_lead, toggle_tier3_workers, toggle_tier4_qa, toggle_external_tools, toggle_shader_editor, toggle_undo_redo_history, toggle_command_palette

Layout (3 new): show_all_panels, hide_all_panels, save_workspace_profile, show_workspace_manager

Theme (1 new): cycle_theme (Dark -> Light -> NERV cycle)

Tools (2 new): undo, redo

Project (1 new): save_all (flush to project + config + global config)

Help (1 new): show_command_palette_help (opens docs/Readme.md in Text Viewer)

Refactored: extracted _toggle_window and _toggle_attr helpers to reduce duplication and make commands safer (no-op if state is missing).

Reset session now also clears comms and tool logs (matches the menu item behavior).

Added 7 new unit tests for the expanded command library.
