Migrate from ArgumentParser to Swift Configuration

Replace ArgumentParser with Swift Configuration for unified CLI and
environment variable configuration management. This migration follows
the CelestraCloud pattern and provides better fault tolerance and
automatic type conversion.

**New Configuration Infrastructure:**
- ConfigurationLoader: Actor-based configuration management with
  CommandLineArgumentsProvider and EnvironmentVariablesProvider
- ConfigurationKeys: Centralized key definitions with dual-key fallback
  (CLI arguments and environment variables)
- BushelConfiguration: Configuration structs with validation pattern
  transforming optional to non-optional fields

**Command Updates:**
- SyncCommand: Removed 13 @Option/@Flag properties, ~110 lines reduced
- ExportCommand: Removed 8 @Option/@Flag properties, ~110 lines reduced
- StatusCommand: Removed 5 @Option/@Flag properties, ~120 lines reduced
- ListCommand: Removed 6 @Option/@Flag properties, ~50 lines reduced
- ClearCommand: Removed 5 @Option/@Flag properties, ~60 lines reduced

**CLI Updates:**
- BushelCloudCLI: Replaced AsyncParsableCommand with manual subcommand
  dispatch using simple switch statement
- Package.swift: Removed ArgumentParser dependency, added Swift
  Configuration with CommandLineArguments trait
- Updated platform requirements: macOS 15+, iOS 18+, watchOS 11+

**Benefits:**
- Unified configuration: Single ConfigurationLoader handles both CLI
  arguments and environment variables
- Automatic type conversion for String, Int, Double, Bool
- Secrets handling with automatic redaction
- Better fault tolerance: Invalid values fall back to defaults
- Cleaner code: ~450 lines of boilerplate removed

All commands maintain the same CLI argument syntax while using a
significantly cleaner implementation.
