feat: Implement dynamic version detection and passing system

**Installation System Updates**:
- install-remote.ps1: Auto-detect version from GitHub API and pass to installer
- Install-Claude.ps1: Accept dynamic version via -SourceVersion parameter
- install-remote.sh: Synchronize version detection logic with PowerShell version
- Add installer_version field to version.json for tracking

**Codex Agent Optimization** (.codex/AGENTS.md):
- Add system optimization requirements for direct binary execution
- Prioritize apply_patch tool over Python scripts for file editing
- Add Windows UTF-8 encoding configuration for Chinese character support

**Version Flow**:
1. install-remote.* detects version from GitHub API (latest release tag)
2. Passes version to Install-Claude.* via -SourceVersion/-SourceBranch
3. Installer writes accurate version to version.json
