Subject: [PATCH 02/13] refactor: implement reset-to-default pattern with
 centralized defaults

- Add settingDefaults registry in packages/types/src/defaults.ts
- Add settings migration framework with versioned migrations
- Flatten codebaseIndexConfig to top-level keys for consistency
- Create new IndexingSettings UI component in Settings view
- Update SettingsView to pass undefined instead of coerced defaults
- Update ExtensionStateContext types to support optional settings
- Add comprehensive tests for defaults and migrations

Subject: [PATCH 04/13] feat: clear settings matching defaults on every startup

This implements 'Option 2' - every-startup clearing of default values.

- Add clearDefaultSettings() function that checks all settings in
  settingDefaults and clears any that exactly match the default
- Add runStartupSettingsMaintenance() as the main entry point that
  runs both migrations (once) and default clearing (every startup)
- Update ContextProxy to use runStartupSettingsMaintenance
- Add comprehensive tests for the new functionality

This ensures users always benefit from default value improvements.
Note: Users cannot 'lock in' a value that matches the default.

Subject: [PATCH 05/13] feat: expand settingDefaults to include ALL settings
 with defaults

IMPORTANT: Every setting with a default value is now in settingDefaults.
This enables clearDefaultSettings() to properly clear ALL default values
from storage on every startup, ensuring defaults are never persisted.

Added settings:
- Auto-approval: autoApprovalEnabled, alwaysAllowReadOnly, alwaysAllowWrite,
  alwaysAllowBrowser, alwaysAllowMcp, alwaysAllowModeSwitch, alwaysAllowSubtasks,
  alwaysAllowExecute, requestDelaySeconds, followupAutoApproveTimeoutMs, etc.
- Terminal: terminalShellIntegrationDisabled, terminalCommandDelay,
  terminalPowershellCounter, terminalZsh*, terminalCompressProgressBar
- Other: diagnosticsEnabled, historyPreviewCollapsed, hasOpenedModeSelector,
  enableMcpServerCreation, rateLimitSeconds

Removed settings:
- diffEnabled, fuzzyMatchThreshold (removed from schema)

Updated test expectations to match new comprehensive defaults list.

Subject: [PATCH 06/13] fix: remove codebaseIndexModels from globalState
 storage

EMBEDDING_MODEL_PROFILES was being stored in globalState on every
ClineProvider initialization, but this is unnecessary - it's static
reference data that should be passed directly to the webview.

Changes:
- Remove line that stored EMBEDDING_MODEL_PROFILES in globalState
- The webview still receives the data via the ?? fallback in getState()
- Add migration v3 to clean up existing codebaseIndexModels keys
- Add tests for migration v3

 defaults
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add ResetToDefault component with ↺ icon that shows when a setting
  differs from its default value
- Tooltip shows the default value (e.g., 'Reset to default (true)')
- Component only renders when current value !== default
- Add translation keys for boolean/empty/resetToDefault formatting
- Integrate with BrowserSettings as proof of concept:
  - browserToolEnabled checkbox
  - browserViewportSize dropdown
  - screenshotQuality slider
- Add comprehensive tests for visibility, functionality, and styling

Subject: [PATCH 08/13] fix: display default values when settings are reset to
 undefined

- Use settingDefaults fallback for checkbox checked state
- Use settingDefaults fallback for conditional rendering
- Use settingDefaults fallback for Select value

This ensures that when a setting is reset to undefined (meaning 'use default'),
the UI displays the actual default value instead of showing undefined/empty state.

 object

The webviewMessageHandler was passing section as 'tab' property but
App.tsx expects it in 'values.section'. This fixes the navigation from
CodeIndexPopover 'Configure in Settings' link to the indexing tab.

Subject: [PATCH 11/13] fix: add missing translations and fix TerminalSettings
 props

- Add 10 missing translation keys to all 17 supported locales:
  - common.true, common.false, common.empty, common.resetToDefault
  - sections.indexing
  - codeIndex.stopIndexingButton, codeIndex.configureInSettings
  - codeIndex.enableInSettings
  - codeIndex.apiKeyNote.title, codeIndex.apiKeyNote.description

- Fix TerminalSettings component props to use the correct numeric
  settings (terminalOutputLineLimit, terminalOutputCharacterLimit,
  terminalCompressProgressBar) instead of the old enum-based
  terminalOutputPreviewSize

- Remove unused Select component imports
