vh d0882fb830 feat(althing): four-surface deploy script + runbook
Deploying althing touches four independent surfaces on nh3-dev. Three
were known. The fourth -- the plugin -- had no step in any runbook and
drifted for five days before anyone noticed.

The plugin chain is repo plugin/ to the marketplace directory to Claude
Code's cache, and neither hop was automated. The marketplace directory
was a frozen copy from Aug 28 carrying only the UserPromptSubmit hook,
with no SessionStart, no SessionEnd and no pane-route.sh at all. So the
claim that CC seats re-declare their pane route automatically at session
start was never true on this box, which is why every seat had to be
hand-declared with a pid measured by hand.

The script backs up the marketplace directory before syncing, re-stamps
its marketplace.json from the repo's plugin.json, and uses `claude plugin
update` for the cache rather than hand-editing installed_plugins.json --
that is Claude Code's own bookkeeping and a subtle mistake there breaks
the plugin in a way that looks like an upstream bug.

The runbook also carries the two things most likely to waste someone's
afternoon: `uv tool install .` without --force is a silent no-op that
exits 0 having done nothing, and a live waiter reporting mode:pull is a
seat that will never be poked, with the audit loop for finding them.

# Deploy althing on this box. FOUR surfaces, not three — the fourth is the one
# that had no step and drifted for five days without anyone noticing.
#
# scripts/deploy-althing.sh deploy
# scripts/deploy-althing.sh --check report drift, change nothing
#
# ─────────────────────────────────────────────────────────────────────────────
# WHY FOUR
#
# 1. uv tool install --force . the 7 binaries (postbox, althing-listen,
# althing-route, althing-po-herald, ...)
# 2. herald restart guards live in the herald; nothing new takes
# effect until it restarts
# 3. scripts/sync_skill.sh the machine-global participant skill
# 4. PLUGIN repo plugin/ -> marketplace dir -> CC cache
#
# Surface 4 is two hops and NEITHER was automated. The marketplace directory
# was a frozen copy from 2026-08-28 carrying plugin 0.0.1 with ONLY the
# UserPromptSubmit hook — no SessionStart, no SessionEnd, no pane-route.sh.
# Consequence: "CC seats re-declare their pane route automatically at next
# SessionStart" was never true on this box, which is why every seat had to be
# hand-declared with a pid someone measured by hand.
#
# ⚠ `uv tool install .` WITHOUT --force IS A SILENT NO-OP. uv matches the
# source SPEC, not its contents: on a box that already installed from this
# path it prints "already installed" and exits 0 having done nothing.
#
# ⚠ The plugin cache update needs a Claude Code RESTART to take effect. The
# hooks are read at session start; a running session keeps the old ones.
