feat: add Gemini CLI provider integration (#647)

* feat: add Gemini CLI provider for AI model execution

- Add GeminiProvider class extending CliProvider for Gemini CLI integration
- Add Gemini models (Gemini 3 Pro/Flash Preview, 2.5 Pro/Flash/Flash-Lite)
- Add gemini-models.ts with model definitions and types
- Update ModelProvider type to include 'gemini'
- Add isGeminiModel() to provider-utils.ts for model detection
- Register Gemini provider in provider-factory with priority 4
- Add Gemini setup detection routes (status, auth, deauth)
- Add GeminiCliStatus to setup store for UI state management
- Add Gemini to PROVIDER_ICON_COMPONENTS for UI icon display
- Add GEMINI_MODELS to model-display for dropdown population
- Support thinking levels: off, low, medium, high

Based on https://github.com/google-gemini/gemini-cli

* chore: update package-lock.json

* feat(ui): add Gemini provider to settings and setup wizard

- Add GeminiCliStatus component for CLI detection display
- Add GeminiSettingsTab component for global settings
- Update provider-tabs.tsx to include Gemini as 5th tab
- Update providers-setup-step.tsx with Gemini provider detection
- Add useGeminiCliStatus hook for querying CLI status
- Add getGeminiStatus, authGemini, deauthGemini to HTTP API client
- Add gemini query key for React Query
- Fix GeminiModelId type to not double-prefix model IDs

* feat(ui): add Gemini to settings sidebar navigation

- Add 'gemini-provider' to SettingsViewId type
- Add GeminiIcon and gemini-provider to navigation config
- Add gemini-provider to NAV_ID_TO_PROVIDER mapping
- Add gemini-provider case in settings-view switch
- Export GeminiSettingsTab from providers index

This fixes the missing Gemini entry in the AI Providers sidebar menu.

* feat(ui): add Gemini model configuration in settings

- Create GeminiModelConfiguration component for model selection
- Add enabledGeminiModels and geminiDefaultModel state to app-store
- Add setEnabledGeminiModels, setGeminiDefaultModel, toggleGeminiModel actions
- Update GeminiSettingsTab to show model configuration when CLI is installed
- Import GeminiModelId and getAllGeminiModelIds from types

This adds the ability to configure which Gemini models are available
in the feature modal, similar to other providers like Codex and OpenCode.

* feat(ui): add Gemini models to all model dropdowns

- Add GEMINI_MODELS to model-constants.ts for UI dropdowns
- Add Gemini to ALL_MODELS array used throughout the app
- Add GeminiIcon to PROFILE_ICONS mapping
- Fix GEMINI_MODELS in model-display.ts to use correct model IDs
- Update getModelDisplayName to handle Gemini models correctly

Gemini models now appear in all model selection dropdowns including
Model Defaults, Feature Defaults, and feature card settings.

* fix(gemini): fix CLI integration and event handling

- Fix model ID prefix handling: strip gemini- prefix in agent-service,
  add it back in buildCliArgs for CLI invocation
- Fix event normalization to match actual Gemini CLI output format:
  - type: 'init' (not 'system')
  - type: 'message' with role (not 'assistant')
  - tool_name/tool_id/parameters/output field names
- Add --sandbox false and --approval-mode yolo for faster execution
- Remove thinking level selector from UI (Gemini CLI doesn't support it)
- Update auth status to show errors properly

* test: update provider-factory tests for Gemini provider

- Add GeminiProvider import and spy mock
- Update expected provider count from 4 to 5
- Add test for GeminiProvider inclusion
- Add gemini key to checkAllProviders test

* fix(gemini): address PR review feedback

- Fix npm package name from @anthropic-ai/gemini-cli to @google/gemini-cli
- Fix comments in gemini-provider.ts to match actual CLI output format
- Convert sync fs operations to async using fs/promises

* fix(settings): add Gemini and Codex settings to sync

Add enabledGeminiModels, geminiDefaultModel, enabledCodexModels, and
codexDefaultModel to SETTINGS_FIELDS_TO_SYNC for persistence across sessions.

* fix(gemini): address additional PR review feedback

- Use 'Speed' badge for non-thinking Gemini models (consistency)
- Fix installCommand mapping in gemini-settings-tab.tsx
- Add hasEnvApiKey to GeminiCliStatus interface for API parity
- Clarify GeminiThinkingLevel comment (CLI doesn't support --thinking-level)

* fix(settings): restore Codex and Gemini settings from server

Add sanitization and restoration logic for enabledCodexModels,
codexDefaultModel, enabledGeminiModels, and geminiDefaultModel
in refreshSettingsFromServer() to match the fields in SETTINGS_FIELDS_TO_SYNC.

* feat(gemini): normalize tool names and fix workspace restrictions

- Add tool name mapping to normalize Gemini CLI tool names to standard
  names (e.g., write_todos -> TodoWrite, read_file -> Read)
- Add normalizeGeminiToolInput to convert write_todos format to TodoWrite
  format (description -> content, handle cancelled status)
- Pass --include-directories with cwd to fix workspace restriction errors
  when Gemini CLI has a different cached workspace from previous sessions
