feat(500): one end-of-turn request - the completion-section check folds into the reply check
The Stop hook sent the finished reply twice: scribe_report_check.sh checked a
task-closing reply for the completion sections in shell and reported to
/report-check, and scribe_reply_check.sh sent the same reply to /reply-rules
for the rule hold. Now the reply goes once. When the turn closed a task the
hook adds the close count and ids, and the server runs the section check
(services/report_check, the same three patterns) beside the reply hold,
folding both into one reason.

The report_check adherence log is still written for every checked reply
(milestone 409's number). A section hold marks the session, so its rewrite is
sent back once with rewrite:true to record how it came out, and is never held.
The block reason carries the completion shape's one line and points at
list_reply_shapes rather than at the skill. #5496 (step 4 of milestone 500).

# Scribe plugin — Stop hook: the turn's new shapes are judged by the agent
# that wrote them (milestone 439).
#
# The write hooks (scribe_prior_art.sh, scribe_after_write.sh) append every
# definition a write names to a session ledger, `<sid>.written.ids`
# (`path<TAB>kind<TAB>name`, see scribe_written_append). At the end of the
# turn this hook sends that ledger to the instance, which answers with what
# nobody has judged yet. If anything is, the hook blocks ONCE, in the server's
# words: the agent that built the code is the one participant who knows what
# it is, and the end of the turn is the last moment that is still true.
#
# THE SAME DISCIPLINE AS the completion-section check in scribe_reply_check.sh:
# - it blocks only on a `reason` the instance returned, which it returns
# only for a block it RECORDED — an unconfigured or unreachable instance
# never stops a session, and every intervention is one the numbers see;
# - never twice for one turn: the stop that follows its own block
# (`stop_hook_active` with this hook's marker present) is recorded as
# judged_after_block / left_after_block and let through;
# - another plugin's block loop is left alone (active, no marker).
#
# THE LEDGER IS CONSUMED, NOT TURN-STAMPED. Everything written since the last
# stop this hook answered is "this turn". It is emptied once the instance has
# answered — after a pass, or after the post-block stop — and KEPT when the
# instance could not be reached, so the question is asked at the next stop
# that can be answered rather than silently dropped.
#
# Config (same as the other hooks):
# CLAUDE_PLUGIN_OPTION_API_ENDPOINT base URL, no trailing slash
# CLAUDE_PLUGIN_OPTION_API_TOKEN fmcp_ API key (sensitive)
# SCRIBE_URL / SCRIBE_TOKEN override for the settings.json dogfooding path.
