improvise-7epn: two cases on the one-tick-per-read clock. One resolves on
poll 3, and one times out after polling up to the deadline. Replacing the
post-poll deadline check with `break` now fails exactly those two
(23 passed, 2 failed), where before it left the suite 23/23.
improvise-lnsh: when `cargo metadata --locked` refuses the opfs-contract
lock, build.sh now says not to remove --locked and names
`cargo update -w --manifest-path harness/opfs-contract/Cargo.toml`.
Checked by hand against a lock with pest pinned to 2.9.1. Evidence is in
context/test-evidence/tooling.md.
