docs(coord-send): correct a false claim the fallback fix shipped with

v0.12.1's fix removed the ~/.claude/scripts fallback but its own commentary
still asserted the deployed copy was "real and intentional (the operator's
own terminal aliases point at it)". Checked directly with the operator:
they invoke coord-send and board only through their Skill front doors, never
a personal terminal alias. board.sh and route.sh never had a deployed copy
at all -- only the five coord-*.sh scripts did, and their one measured
effect was as an accidental fallback target for Claude sessions' own Bash
tool calls, the exact bug 0.12.1 fixed. With no owner and no remaining
function, the five files under ~/.claude/scripts/ have been deleted.

No behavior change -- coord-selftest.sh still 159/159.
