Platform-Specific Binary Downloads

[butschster]

This PR implements platform and architecture detection for the self-update command, allowing it to download the appropriate binary based on the user's system.

Changes

• Created a new BinaryNameBuilder class to generate platform-specific binary names (e.g., ctx-1.22.0-darwin-arm64)

How It Works

1. The system detects the current platform (linux, darwin, windows) and architecture (amd64, arm64)
2. It first attempts to download the platform-specific binary (e.g., ctx-1.22.0-linux-amd64)
3. If that fails, it automatically falls back to the generic binary format (e.g., ctx or ctx.phar)
4. All existing functionality is preserved for environments where detection isn't possible

Fix: Self-update command fails with "Text file busy" error

When executing the self-update command, the application was trying to overwrite the currently running PHAR file, which resulted in the following error:

Warning: file_put_contents(/usr/local/bin/ctx): Failed to open stream: Text file busy in phar:///usr/local/bin/ctx/src/Lib/Files.php on line 41

I've implemented a robust binary updating system that handles the "Text file busy" scenario:

1. Created a BinaryUpdater class that:

   • First attempts a direct update (which works if the file isn't busy)
   • Falls back to platform-specific update strategies if direct update fails

2. Implemented platform-specific update strategies:

   • UnixUpdateStrategy - Creates a bash script that runs after the process exits
   • WindowsUpdateStrategy - Creates a batch script for Windows environments

3. Updated SelfUpdateCommand to use the new BinaryUpdater system

The update process now:

1. Downloads the new version to a temporary file
2. Tries to directly update the binary (may work in some cases)
3. If that fails, creates and executes a background script that:
   • Waits for the parent process to exit
   • Tries multiple times to replace the binary
   • Provides appropriate feedback to the user
   • Cleans up temporary files

This approach ensures that the update completes successfully even when the binary is currently in use, and it works correctly across different platforms.
