The client (connection.rs) and native daemon (native/daemon.rs) used
different get_port_for_session() implementations on Windows:
- Client: i32, .chars(), djb2 — (hash << 5) - hash + c
- Daemon: i64, .bytes(), Java hashCode — hash * 31 + b
For session name "default", client computes port 50838 while the
daemon binds on 51174, causing a 5-second timeout and startup failure.
Fix: align native/daemon.rs to use the identical djb2 algorithm from
connection.rs (i32, chars, djb2), so both sides agree on the port.
Unix is unaffected (uses Unix domain sockets, no port hashing).
Tests: add port hash regression tests to all three implementations
(native/daemon.rs, connection.rs, daemon.ts) to prevent future drift.
