Go standard library extension, adding the missing parts used in the foomo ecosystem to keep DRY.

• fmt — Template string formatting with %{.key} syntax
• net — Free port allocation for tests and local development
• options — Generic functional options pattern (Option, OptionE, Builder, BuilderE)
• os — Typed Getenv/MustGetenv for scalars, slices, and maps with defaults
• runtime — Enriched caller introspection (Caller, CallerFunc, StackTrace) and panic recovery
• sec — Safe path joining to prevent directory traversal (gosec G304)
• slices — Generic slice utilities: Filter, Map, GroupBy (with error variants)
• slog — Test-friendly slog.Handler that writes to testing.TB output
• strings — Case conversions, padding, validation, prefix/suffix matching, and composition
• testing — Tag-based test filtering via GO_TEST_TAGS, crypto key helpers, ExampleTB
• time — Context-aware Sleep
