feat(scripts): import coord engine verbatim from the local install

Browse source 
coord-send.sh, coord-inbox.sh, coord-done.sh and the 40-check
coord-selftest.sh, unchanged, as the extraction baseline. Selftest
passes 40/40 in this location (script paths are dir-relative).

#!/bin/bash
# coord-inbox.sh - read this repo's PENDING inbox + unseen broadcasts from the
# local coordination mailbox (~/.claude/coord), print them formatted for
# injection with per-message reply/resolve hints.
#
# IDEMPOTENT by design: directed messages are NOT archived on read - they stay
# pending and are re-injected on every SessionStart (startup, /clear, resume)
# until marked handled with coord-done (so /clear never loses them, and this is
# safe to re-run manually mid-session). Broadcasts are delivered once per repo
# via a filename watermark. Prints nothing (exit 0) when nothing is pending.
# ASCII only, bash 3.2 safe.
#
# Usage: coord-inbox.sh [--repo <name>]
# Env: CLAUDE_COORD_DIR overrides the mailbox root.
