fix: improve package quality and fix goose-cli build

- Add meta.platforms to all packages for proper platform detection
- Add passthru.category to mcp-gateway for consistency
- Fix meta style inconsistency in mcp-gateway (lib.licenses → licenses)
- Fix pythonImportsCheck in skillsmcp to actually validate the import
- Remove empty maintainers list from skillsmcp
- Add libclang to goose-cli nativeBuildInputs (fixes bindgen/llama-cpp-sys-2 build)
- Add treefmt.toml with nixfmt formatter configuration
- Add nixConfig.extra-substituters for binary cache support
- Delete broken goose-cli/update.py (referenced missing scripts/updater.py)
- Document nix-update usage in AGENTS.md for package updates
- Fix stale project structure diagram in README
