Snider 5be20af4b0 feat: eliminate fmt, string concat — add core.Println, use Concat/Path everywhere
New primitive: core.Println() wraps fmt.Println.

Replaced across all test + example files:
- fmt.Println → Println (17 example files)
- fmt.Sprintf → Concat + Sprint
- dir + "/file" → Path(dir, "file") (path security)
- "str" + var → Concat("str", var) (AX consistency)

"fmt" import is now zero across all test files.
String concat with + is zero across all test files.

Remaining 9 stdlib imports (all Go infrastructure):
testing, context, time, sync, embed, io/fs, bytes, gzip, base64

558 tests, 84.5% coverage.
