chore: optimize release profile for fullstack and add linux static build target

- Change opt-level from 'z' to 3 for better runtime performance
- Use thin LTO for faster compilation with similar results
- Remove panic=abort and strip=true to preserve server debuggability
- Add --debug-symbols=false to dx build for smaller WASM
- Add build-linux target for static musl binary
