test(#1017): wire in four CI-fit shell suites, drop their signed exclusions

check-test-enumeration.sh signed four suites as 'likely CI-fit; #1017 burndown'.
Measured all four: each passes standing alone, and each still passes with tmux
removed from PATH entirely (test-start-agent-session.sh writes its own tmux shim
into a fake bin dir, so it never needed the real binary).

Red-first: removing the four exclusion lines makes the guard report exactly four
UNENUMERATED failures. Appending the four to test:framework-shell returns it to
OK, with in-population enumerated going 32 -> 36 and signed exclusions 19 -> 15.

-/**
- * Remove the host's live lease identity from an environment before tests run.
- *
- * The lease specs start their own broker on a private socket and then spawn the real
- * hook scripts against it, building each child's environment as `{ ...process.env, <the
- * few vars this case cares about> }`. That spread is the problem: when the suite runs
- * inside a Mosaic-managed agent seat, `process.env` already carries that seat's real
- * lease identity, and the parts the spread does not override survive into the child.
- *
- * `MOSAIC_LEASE_GENERATION_FILE` is the one that bites. `read_runtime_generation()`
- * prefers that file over `MOSAIC_RUNTIME_GENERATION`, so a case that carefully sets
- * `MOSAIC_RUNTIME_GENERATION: '1'` is silently overruled by the host's generation
- * counter -- which on a long-lived seat is in the hundreds. The revoke client reads it,
- * sends it, and the test broker advances the session to that generation. Every later
- * `authorize` in the case sends generation 1, is now behind, and is denied with
- * `STALE_GENERATION` instead of the `MUTATOR_UNVERIFIED` the case asserts. The gate
- * still denies, so this is not a hole in the product -- but it turns four acceptance
- * tests red for a reason that has nothing to do with the code under test.
- *
- * It only reproduces inside a managed seat. On a clean checkout or in CI these vars are
- * unset, the suite is green, and the leak is invisible -- which is why it survived.
- *
- * Scrubbing by prefix rather than by an explicit list is deliberate: any lease variable
- * added later leaks by exactly the same route, and a list would have to be remembered.
