tests: document AFP get-entry-id-from-name smoke coverage

Document the Linux smoke coverage for NCP 0x23/0x04 AFP Get Entry ID From Name after the path-backed implementation was verified.

The same afp_entry_id_smoke tool now exercises both the older path-name probe and the name-based entry-id lookup. Record the --from-name examples for SYS:, SYS:PUBLIC, SYS:SYSTEM, and SYS:BURST, and note that the current implementation still returns stat-derived fallback Entry IDs until persistent CNID/AppleDouble mapping is available.

Update TODO.md so the implemented AFP status matches the tested endpoints while keeping the remaining base-entry-id-relative lookup and persistent Mac namespace work tracked as follow-up.
