feat: Add GitHub Copilot SDK provider integration (#661)

* feat: add GitHub Copilot SDK provider integration

Adds comprehensive GitHub Copilot SDK provider support including:
- CopilotProvider class with CLI detection and OAuth authentication check
- Copilot models definition with GPT-4o, Claude, and o1/o3 series models
- Settings UI integration with provider tab, model configuration, and navigation
- Onboarding flow integration with Copilot setup step
- Model selector integration for all phase-specific model dropdowns
- Persistence of enabled models and default model settings via API sync
- Server route for Copilot CLI status endpoint

* chore: update package-lock.json

https://claude.ai/code/session_01D26w7ZyEzP4H6Dor3ttk9d

* refactor: rename Copilot SDK to Copilot CLI and use GitHub icon

- Update all references from "GitHub Copilot SDK" to "GitHub Copilot CLI"
- Change install command from @github/copilot-sdk to @github/copilot
- Update CopilotIcon to use official GitHub Octocat logo
- Update error codes and comments throughout codebase

* fix: update Copilot model definitions and add dynamic model discovery

- Update COPILOT_MODEL_MAP with correct models from CLI (claude-sonnet-4.5,
  claude-haiku-4.5, claude-opus-4.5, claude-sonnet-4, gpt-5.x series, gpt-4.1,
  gemini-3-pro-preview)
- Change default Copilot model to copilot-claude-sonnet-4.5
- Add model caching methods to CopilotProvider (hasCachedModels,
  clearModelCache, refreshModels)
- Add API routes for dynamic model discovery:
  - GET /api/setup/copilot/models
  - POST /api/setup/copilot/models/refresh
  - POST /api/setup/copilot/cache/clear

* refactor: use @github/copilot-sdk instead of direct CLI calls

- Install @github/copilot-sdk package for proper SDK integration
- Rewrite CopilotProvider to use SDK's CopilotClient API
- Use client.createSession() for session management
- Handle SDK events (assistant.message, tool.execution_*, session.idle)
- Auto-approve permissions for autonomous agent operation
- Remove incorrect CLI flags (--mode, --output-format)
- Update default model to claude-sonnet-4.5

* fix: add Copilot and Gemini model support to model resolver

- Import isCopilotModel and isGeminiModel from types
- Add explicit checks for copilot- and gemini- prefixed models
- Pass through Copilot/Gemini models unchanged to their providers
- Update resolver documentation to list all supported providers

* fix: pass working directory to Copilot SDK and reduce event noise

- Create CopilotClient per execution with correct cwd from options.cwd
- This ensures the CLI operates in the correct project directory, not the
  server's current directory
- Skip assistant.message_delta events (they create excessive noise)
- Only yield the final assistant.message event which has complete content
- Clean up client on completion and error paths

* fix: simplify Copilot SDK execution with sendAndWait

- Use sendAndWait() instead of manual event polling for more reliable
  execution
- Disable streaming (streaming: false) to simplify response handling
- Increase timeout to 10 minutes for agentic operations
- Still capture tool execution events for UI display
- Add more debug logging for troubleshooting
- This should fix the "invalid_request_body" error on subsequent calls

* fix: allow Copilot model IDs with claude-, gemini-, gpt- prefixes

Copilot's bare model IDs legitimately contain prefixes like claude-,
gemini-, gpt- because those are the actual model names from the
Copilot CLI (e.g., claude-sonnet-4.5, gemini-3-pro-preview, gpt-5.1).

The generic validateBareModelId function was incorrectly rejecting
these valid model IDs. Now we only check that the copilot- prefix
has been stripped by the ProviderFactory.

* feat: enable real-time streaming of tool events for Copilot

- Switch back to streaming mode (streaming: true) for real-time events
- Use async queue pattern to bridge SDK callbacks to async generator
- Events are now yielded as they happen, not batched at the end
- Tool calls (Read, Write, Edit, Bash, TodoWrite, etc.) show in real-time
- Better progress visibility during agentic operations

* feat: expand Copilot tool name and input normalization

Tool name mapping additions:
- view → Read (Copilot's file viewing tool)
- create_file → Write
- replace, patch → Edit
- run_shell_command, terminal → Bash
- search_file_content → Grep
- list_directory → Ls
- google_web_search → WebSearch
- report_intent → ReportIntent (Copilot-specific planning)
- think, plan → Think, Plan

Input normalization improvements:
- Read/Write/Edit: Map file, filename, filePath → file_path
- Bash: Map cmd, script → command
- Grep: Map query, search, regex → pattern

* fix: convert git+ssh to git+https in package-lock.json

The @electron/node-gyp dependency was resolved with a git+ssh URL
which fails in CI environments without SSH keys. Convert to HTTPS.

* fix: address code review feedback for Copilot SDK provider

- Add guard for non-text prompts (vision not yet supported)
- Clear runtime model cache on fetch failure
- Fix race condition in async queue error handling
- Import CopilotAuthStatus from shared types
- Fix comment mismatch for default model constant
- Add auth-copilot and deauth-copilot routes
- Extract shared tool normalization utilities
- Create base model configuration UI component
- Add comprehensive unit tests for CopilotProvider
- Replace magic strings with constants
- Add debug logging for cleanup errors

* fix: address CodeRabbit review nitpicks

- Fix test mocks to include --version check for CLI detection
- Add aria-label for accessibility on refresh button
- Ensure default model checkbox always appears checked/enabled

* fix: address CodeRabbit review feedback

- Fix test mocks by creating fresh provider instances after mock setup
- Extract COPILOT_DISCONNECTED_MARKER_FILE constant to common.ts
- Add AUTONOMOUS MODE comment explaining auto-approval of permissions
- Improve tool-normalization with union types and null guards
- Handle 'canceled' (American spelling) status in todo normalization

* refactor: extract copilot connection logic to service and fix test mocks

- Create copilot-connection-service.ts with connect/disconnect logic
- Update auth-copilot and deauth-copilot routes to use service
- Fix test mocks for CLI detection:
  - Mock fs.existsSync for CLI path validation
  - Mock which/where command for CLI path detection
