Added:

- Workspace support (`[workspace]` with deps ordering)
- `clean --all` for workspace members
Changed:
- Project root discovery for `build/run/clean` (searches parent dirs)
- Workspace paths are excluded from root source scan
- Build output now uses a Cargo-style `Compiling <name> v<version>` line
- Build time now reports total time for the whole build stage (workspace included)
- Cache hits are silent (no compile line when nothing is rebuilt)
- Safer build cache: fingerprints include headers and resolved library files
