fix(effort): resync re-applies the pins after the 21st pack refresh, order locked

The 21st pack refresh (update-all 7.4) rewrites every 21st-* SKILL.md after
the superpowers refresh; the re-apply now sits after it, the census locks
the order in both scripts. Contract: criterion 3 anchor, shellcheck
directive authorized, tracked design-motion-principles copy gated.

 - Round result: 30 existing entry levels hold against the table; 3 repo skills had none (skills-perso low, pdf-translate medium, site-motion high); vendored externals get theirs from `lib/effort-pins.txt` re-applied by `lib/effort-pins.sh`; impeccable, graphify, find-docs, gstack, darwin-skill and the five shifters stay unpinned (machine-owned, BDR-107).
 - Defect found in passing, fixed here: `update-all.sh` re-fetched the vendored skills but never re-applied the pins (lost until the next `make plugin`).
 - Defect found in passing, surfaced not fixed: ~94 % of sub-agent usage records carry no `output_tokens_details`, so `lib/effort-audit.py` read zero thinking on sub-agents; the script now prints coverage and a CAVEAT; EVAL-037's "executors stay cheap" is a measurement gap (registry correction pending user approval).
+- lib/tests/effort-routing.test.sh line 4 widens its shellcheck directive from SC2015 to SC2015,SC2016: the new `has … '$REPO'` locks are literal source text, the `$REPO` must NOT expand (authorized; a test file, informational). [verifier 2026-09-29 gap 3]
 - Frontmatter placement of the inserted `effort:` line (after `name:`, else before the closing `---`) has no harness effect; locked by the fixture suite only.
