veg f06c599ea7 fix: reject '.' and leading '-' in party names
tmux session_check_name() silently rewrites '.' to '_', so a dotted
party name desyncs from its tmux session and every -t lookup fails
(verified on tmux 3.3a through 3.6b). Leading-dash names can never be
addressed through the CLI parsers.

# ========
#
# is_party_alive must not probe the PID with kill -0. POSIX kill(2) is
# allowed to return EPERM when the caller can't signal the target, and
# illumos/BSD/macOS honor that — so kill -0 against another user's PID
# returns nonzero even when the process exists. Linux and Linux-ABI
# zones (LX-branded) are the outliers that return 0; that's why the
# bug hid in the test matrix until a native illumos run surfaced it.
# Discovery now relies on `tmux -S list-clients` alone, which is
# strictly stronger (filters PID-reuse, dead servers, AF_UNIX impostors).
