* fix(mcp): promote gnubok_update_customer to the default tools/list catalog
The tool existed since #1876 but was catalogVisibility 'search', which
means it appeared only through gnubok_search_tools. Claude.ai (and other
list-driven clients) can only call tools present in tools/list, so on the
primary connector the tool was uncallable and the reporter of #1706 read
it as missing twice.
- server.ts: drop the 'search' flag on gnubok_update_customer; no change
to schema, executor, scopes, risk tier, or staging path
- update-customer.test.ts: pin the tools/list projection
(isDefaultCatalogTool) instead of the flag; keep the search test
- payload-size.bench.test.ts: ceiling 63_400 to 64_100 (measured 64 043,
+761 over main) with a progression bullet
- README.md: note that search-only tools are not callable from Claude.ai
- DECISIONS.md: supersede the 2026-08-25 keep-search-only entry
Closes#1706

* test(mcp): re-measure the tools/list ceiling after #1993 landed on main
#1993 declared line_type and revenue_account on the create item schema,
which moved the accounted projection to 63 761 with gnubok_update_customer
promoted; ceiling 63_800 keeps the same headroom as before.
