dimgigov 9e515c157d feat(pkg): add basic package manager (add, remove, fetch, build deps) 
- manifest.bux: parse [dependencies] section with up to 8 deps
- manifest.bux: Manifest_AddDep, Manifest_RemoveDep, Manifest_ToString
- cli.bux: bux add <name> <url> — adds dependency to bux.toml
- cli.bux: bux remove <name> — removes dependency from bux.toml
- cli.bux: bux fetch — git clone/pull dependencies into deps/
- cli.bux: Cli_BuildProject now merges deps/<name>/src/*.bux before user code
- Selfhost bootstrap loop verified: C output deterministic ✓
