fix(release): Back to binary download, add executable permissions

Cargo install failed (exit code 101):
- Package may not exist in crates.io
- Or dependency resolution failed

Back to binary download with fixes:
- Reinstalled wget download method
- Added chmod +x for executable permissions
- Ensured version extraction happens before changelog steps
- Proper bash variable interpolation

Changes:
1. Fixed step order:
   - Extract version now happens before changelog steps
   - Prevents undefined VERSION variable

2. Added executable permissions:
   - chmod +x /usr/local/bin/git-cliff
   - Ensures git-cliff can be executed

3. Simplified workflow:
   - Removed Rust toolchain (not needed for binary)
   - Back to reliable binary download
   - 2-3 seconds vs 30-60 seconds (cargo install)

This should resolve cargo installation failure and ensure git-cliff is installed correctly.
