fix(governance): leave the slow lanes to CI, not to orly gate pr

orly runs `verify.integration` and `verify.memory` as a slow tier inside
`orly gate pr`, so declaring them in `.oracle/orly.json` turned a
one-second boundary check into a full `make test-integration` plus
`make memleak` run — real Postgres, real Redis, valgrind over the Zig test
graph. Those lanes already have CI workflows, which is where this repository
put them on purpose.

The config now declares `conform`, `verify.lint`, `verify.unit`, and
`verify.version`. `orly gate pr` is back to 0.45s and still grades every
criterion that makes a Pull Request reviewable: tree state, push state, the
spec gate, open questions, product clarity, dimensions, the spec move,
the Test Baseline, commit ordering, deferral acks, and docs parity.

The spec rubrics are unaffected — the gate's declared-command parity check
reads `conform` and `verify.unit`, both still declared, and
`make test-integration` / `make memleak` remain rubric rows in the specs that
were already citing them.
