feat: Add Windows support and stabilize SDK installation (v1.0.0-rc1)

Complete Windows compatibility overhaul with robust cross-platform SDK management.
This release candidate establishes feature freeze for the 1.0.0 release.

Key improvements:
- Fixed Android SDK installation on Windows
  * Use cmd.exe wrapper for sdkmanager.bat with piped stdin
  * Properly reorganize cmdline-tools directory structure
  * Write license acceptances synchronously to avoid hangs

- Fixed FTC SDK configuration
  * Auto-generate local.properties with Android SDK path
  * Escape backslashes in Kotlin build.gradle.kts strings
  * Support both new installs and upgrades via ensure_local_properties()

- Enhanced Windows console output
  * Enable ANSI color support via enable_ansi_support crate
  * Maintain color compatibility across Windows versions

- Improved error handling and debugging
  * Added comprehensive logging throughout SDK installation
  * Better context messages for troubleshooting failures

Cross-platform testing verified on:
- Windows 11 with Eclipse Adoptium JDK 21
- Linux (existing support maintained)

Breaking changes: None
This RC introduces feature freeze - subsequent 1.0.x releases will be
bug fixes only. New features deferred to 1.1.0.

Closes Windows compatibility milestone.
