Document the Linux AFP Entry ID smoke-test coverage after the endpoint was verified against the standard SYS volume paths.
The test exercises the WebSDK-documented NCP 0x23/0x0c AFP Get Entry ID From Path Name request by logging in through libncp, allocating a temporary directory handle for the volume root, and sending the relative path to the AFP endpoint.
Record the verified SYS:, SYS:PUBLIC, SYS:SYSTEM, and SYS:BURST cases, and describe the current stat-derived fallback Entry ID diagnostics so the result is not confused with persistent CNID/AppleDouble storage.
Keep the remaining AFP work tracked in TODO.md, including replacing the fallback with persistent CNID/directory-id mapping and extending tests when additional AFP subfunctions are implemented.
This is documentation-only and does not change AFP protocol behavior.
Add an optional Linux-side smoke test for the first implemented NetWare AFP endpoint.
The WebSDK documents NCP 0x2222/35/12 AFP Get Entry ID From Path Name as taking a NetWare directory handle and path string and returning a 32-bit AFP entry id. MARS-NWE now has a guarded implementation of that probe when the optional Netatalk/libatalk backend is compiled in, but exercising it does not require a real AppleTalk workstation.
Use the ncpfs/libncp client library as the test transport. ncpfs is commonly available on Linux mars_nwe test hosts and its NWRequestSimple() helper builds the same length-prefixed subfunction request format used by normal libncp callers. The test accepts standard ncpfs connection options such as -S, -U, -P, and -n, sends NCP 0x23/0x0c, and prints the returned entry id.
Keep the test out of normal builds behind MARS_NWE_BUILD_LINUX_TESTS because it depends on host ncpfs development headers/library and on a running server. Add an --allow-invalid-namespace mode so builds without the Netatalk backend can still run a negative smoke test and verify that AFP remains unavailable.
This adds test infrastructure only and does not change server protocol behavior.
