feat(workspace): Workspace sidebar + remove catalog + Chat button (#457, #215)

[jeonghun-jj-lee]

Summary

Consolidates PRs #458 (remove catalog) and #459 (workspace sidebar), rebased onto main, with 6 bug fixes and new features.

What changed

Remove catalog (#457)

• Strip amicode.armonia + amicode.catalog view declarations
• Remove dead trees.ts, catalog widget code

Workspace sidebar (opencode#215 AC6)

• WorkspaceTreeProvider renders workspace folders, respects files.exclude, hides .git
• Full context menus: New File, New Folder, Rename, Delete, Copy Path, Copy Relative Path, Reveal in Finder, Open in Terminal, Open to Side, Remove from Workspace, Add Folder
• Live refresh on filesystem changes + workspace folder add/remove
• viewsWelcome for empty workspace state
• Remove stale amicode.runInspector declaration (provider deleted in Inspectors → Work Column: retire the bottom panel #351)

Chat with Amico button

• Yellow SVG chat-bubble icon as the first tree item — no section header overhead
• Mutes (gray icon + '(open)' description) when a chat tab is active
• ChatPanel.onLiveChange callback for cross-component state tracking

Bug fixes (from Raghav's original code)

1. .startsWith('.git') filter was hiding .gitignore/.github — now only hides the .git directory itself
2. Built-in explorer.* commands don't fire in custom trees — registered custom amicode.workspace.* commands
3. Tree didn't listen to onDidChangeWorkspaceFolders — removing a folder left the sidebar stale
4. credential_scanner e2e test: guard opencode-provider assertion for machines without that specific provider

Tests

• 24 new tests covering tree rendering, all context-menu commands, and muted state
• Full suite passes: 101 files, 1217 tests green

Closes #457. Part of opencode#215.

Summary by CodeRabbit

• New Features

  • Added a Workspace view for browsing workspace folders and files.
  • Added actions to create, rename, delete, and open files and folders.
  • Added path copying, OS reveal, terminal opening, side-by-side opening, and workspace-folder management.
  • Workspace view now shows chat activity and refreshes as panels change.

• Changes

  • Replaced the Catalog view and catalog-card experience with the Workspace view.
  • Saving pulses now uses a user-selected file location.
  • Added an empty-state welcome prompt for new workspaces.

📝 Walkthrough

Walkthrough

The extension removes the catalog UI and catalog-card flow. It adds a workspace tree with file and folder operations, updates activation and context-menu contributions, tracks chat panel activity, and adjusts pulse-save behavior and tests.

Changes

Workspace sidebar migration

Layer / File(s)	Summary
Catalog UI removal and pulse-save changes packages/extension/src/trees.ts, packages/extension/src/extension.ts, packages/extension/src/runs_manager.ts	The session catalog provider and catalog wiring are removed. Pulse saving uses a file destination, and demo promotion directs users to amicode.savePulse.
Workspace tree provider packages/extension/src/workspace_tree.ts	The workspace tree displays folders and files, filters excluded entries, watches changes, opens files, and provides file and folder commands.
Workspace contributions and chat activity packages/extension/package.json, packages/extension/src/extension.ts, packages/extension/src/chat_panel.ts	The extension contributes the amicode.workspace view and workspace commands. Chat panel creation and disposal update the workspace chat state.
Workspace tests and VS Code mocks packages/extension/test/workspace_tree.test.ts, packages/extension/test/__mocks__/vscode.ts, packages/extension/test/credential_scanner.test.ts	Mocks support workspace APIs. Tests cover tree rendering, file operations, context-menu commands, and missing credential handling.

Estimated code review effort: 4 (Complex) | ~45 minutes
