Based on API usage analysis, Peekaboo only requires macOS 14.0 (Sonoma), not macOS 15.0 (Sequoia). The APIs we use:
- SCScreenshotManager.captureImage: macOS 14.0+
- configuration.shouldBeOpaque: macOS 14.0+
- Typed throws syntax: Works with macOS 14.0
This change makes Peekaboo available to more users who haven't upgraded to Sequoia yet.
Also fixed warning about undefined modelName in AI providers by using nullish coalescing.

- Remove problematic AsyncAdapter that was causing continuation leaks
- Use AsyncParsableCommand directly with @main attribute
- Add -parse-as-library flag to Package.swift to enable @main
- This fixes the Swift continuation leak issue
Note: Integration tests still timeout in CI environment, likely due to
screen capture permissions or environment differences. The CLI works
correctly when run directly.

- Add AsyncAdapter.swift to bridge async/sync execution
- Change AsyncParsableCommand back to ParsableCommand
- Implement AsyncRunnable protocol for async execution
- Use DispatchSemaphore pattern for synchronous blocking
- Make ErrorBox thread-safe with @unchecked Sendable
This fixes the CLI execution issue where commands were showing help
instead of executing, by properly bridging the async/sync worlds
as required by ArgumentParser.

- Use proper Swift Testing async patterns for better compatibility
Addresses the issue where searching for 'Chrome' or 'Safari' would incorrectly
match helper processes (like 'Google Chrome Helper (Renderer)') instead of the
main browser application, leading to confusing 'no capturable windows' errors.
Key improvements:
- Added filterBrowserHelpers() method that filters out helper processes for browser searches
- Supports common browsers: chrome, safari, firefox, edge, brave, arc, opera
- Filters out processes containing: helper, renderer, utility, plugin, service, crashpad, gpu, background
- Provides browser-specific error messages when main browser isn't running
- Only applies filtering to browser identifiers, preserves normal matching for other apps
- Comprehensive test coverage for browser filtering scenarios
Example: Searching for 'chrome' now finds 'Google Chrome' instead of
'Google Chrome Helper (Renderer)' which has no capturable windows.

Adds support for capturing the frontmost window of the frontmost application
instead of falling back to screen capture mode.
Changes:
- Added 'frontmost' case to CaptureMode enum in Swift CLI
- Implemented captureFrontmostWindow() method using NSWorkspace.shared.frontmostApplication
- Updated TypeScript to use --mode frontmost instead of defaulting to screen mode
- Added comprehensive test coverage for frontmost functionality
- Updated existing tests to reflect new behavior
The frontmost mode now:
1. Detects the currently active application
2. Captures only its frontmost window (index 0)
3. Returns a single image file with proper metadata

Addresses critical edge case where malformed app targets with multiple leading colons
(e.g., "::::::::::::::::Finder") created empty app names that would match ALL system
processes. This could potentially expose sensitive information or cause unintended
system-wide captures.
Key improvements:
- Enhanced app target parsing to validate non-empty app names
- Added fallback logic to extract valid app names from malformed inputs
- Default to screen mode when all parts are empty (security-first approach)
- Comprehensive test coverage for edge cases
- Improved backward compatibility with hidden path parameters

When users search for windows with URLs containing ports (e.g., 'http://example.com:8080'),
the system now provides much better debugging information when the window isn't found.
Key improvements:
- Enhanced window not found errors now list all available window titles
- Added specific guidance for URL-based searches (try without protocol)
- New CaptureError.windowTitleNotFound with detailed debugging info
- Comprehensive test coverage for colon parsing in app targets
- Better error messages help users understand why matching failed
Example improved error:
"Window with title containing 'http://example.com:8080' not found in Google Chrome.
Available windows: 'example.com:8080 - Google Chrome', 'New Tab - Google Chrome'.
Note: For URLs, try without the protocol (e.g., 'example.com:8080' instead of 'http://example.com:8080')."
This addresses the common issue where browsers display simplified URLs in window titles
without the protocol, making it easier for users to find the correct matching pattern.

Previously, path traversal attempts like `../../../../../../../etc/passwd` were incorrectly
reported as screen recording permission errors instead of file system errors.
Changes:
- Modified ScreenCapture error handling to distinguish between CaptureError types and ScreenCaptureKit errors
- CaptureError.fileWriteError now bypasses screen recording permission detection
- Added path validation in OutputPathResolver to detect and log path traversal attempts
- Added logging for system-sensitive path access attempts
- Comprehensive test coverage for various path traversal patterns and error scenarios
This ensures users get accurate error messages that guide them to the actual problem
(invalid paths, missing directories, file permissions) rather than misleading
screen recording permission prompts.

When multiple applications have exact matches (e.g., "claude" and "Claude"), the system now:
- Captures all windows from all matching applications instead of throwing an ambiguous match error
- Maintains sequential window indices across all matched applications
- Preserves original application names in saved file metadata
- Only returns errors for truly ambiguous fuzzy matches
This provides more useful behavior for common scenarios where users have multiple apps with
similar names (different case, etc.) and want to capture windows from all of them.
Updates:
- Added `captureWindowsFromMultipleApps` method to handle multi-app capture logic
- Modified error handling in both single window and multi-window capture modes
- Updated documentation (spec.md, CHANGELOG.md) to reflect new behavior
- Comprehensive test suite covering various multiple match scenarios

- Invalid screen index (e.g., screen:99) now properly falls back to capturing all screens with unique filenames
- String "null" in path parameter is now correctly treated as undefined instead of literal path
- Added fallback-aware filename generation to prevent file overwrites when screen index is out of bounds
- Comprehensive test coverage for both edge cases
