coord-send.sh:154 guarded the --to target with a `.*` case arm, which
rejects every leading-dot name instead of just `.` and `..`. A
dot-prefixed name is a real repo identity (basename of a git toplevel
under a hidden directory, e.g. ~/.claude) and was reported unreachable
by morning-driver via coord message 20260809T103138Z. Narrowed the
guard to reject exactly `.` and `..`, matching the equivalent guards
already used elsewhere in this file and in coord-done.sh.
coord-count.sh and coord-sweep.sh both enumerate the mailbox root with
a bare "$COORD"/* glob, which by construction never matches a
dot-prefixed directory - confirmed empirically before this change.
Fixing only the send-side guard would have let a dot-prefixed mailbox
receive mail that neither script could ever report or close on its
grace window. Both now also glob "$COORD"/.[!.]* to reach hidden
mailboxes without matching "." or "..".
coord-selftest.sh: 183 -> 191 checks, section 30 covers the fix and
both enumeration paths. Doc counts (README badge, CLAUDE.md) updated
to match; the catalog's mirrored badge is untouched pending release.
