Compress always-on contracts and restore pagination fields

The always-on set is paid by every session, so it gets the tightest
form: git-sync-check shrinks to its procedural core, testing-policy
moves the table-test example to README.md and folds the agent
instructions into the rules, go-code-style inlines the error-wrapping
example. Per-session read cost drops from 403 to 336 lines.

Also restore the pagination response fields in table-management: the
previous dedup replaced them with a reference to go-api, which the
table router line does not load.
