Proof-of-concept proving the protocol-feasibility exit criterion from
docs/architecture/proof-of-concept-plan.md §2:
"Rust can connect to a compatible server/test double."
The spike opens a tsclientlib connection, waits for the BookEvents
state snapshot, subscribes to the server channel tree, prints
server metadata and the channel tree with client names, and
disconnects cleanly. Audio feature is disabled because audio is
covered by a separate PoC.
Verified on 2026-05-13 against cn.teamspeak.app (TeamSpeak 3 server
3.13.7); 36 channels and 5 online clients retrieved with full
UTF-8 (CJK) preservation. See
poc/tsclientlib-connect-spike/VERIFICATION.md for the captured run.
Authority: PoC plan §2, SysRS-005, SysDes-011, SysDes-029.
