Wire the Tleilaxu Ambassador force return

The last unimplemented Ambassador effect is now reachable. A placed Tleilaxu
token gives its beneficiary — the Ecaz owner or its ally — a private
ecazAmbassador decision at the new revival stage: one to four physical counters
return from the Tanks to reserves at zero cost, quoted by the existing
game/tleilaxu-ambassador-forces.ts, which also enforces the shared
Fedaykin/Sardaukar one-per-turn counter and keeps Ixian cyborgs uncapped.

The player view projects the maximum, Tanks and elite inventory and current
elite usage to the beneficiary only; the entry control offers a per-count
button and an explicit "Return no forces" decline; all four AI profiles choose
a legal return from the decision owner's own view or decline when the Tanks are
empty. Player-facing coverage text now lists Tleilaxu.

Kept gated exactly as recorded: the printed leader alternative, ordinary
force/free/leader allowance accounting around this independent grant,
dead-twice eligibility, and Tleilaxu free-income repeat scope. No ordinary
revival allowance, price, phase or income path changes.

Evidence: tests/tleilaxu-ambassador-engine.test.ts drives a genuine arrival into
a placed token and asserts the beneficiary-only projection, the typed return
with unchanged spice, the shared elite limit, malformed/over-maximum rejection
with immutability, the ordinary-only return, the decline path and the rendered
control. The four-profile ecaz-entry-bots loop now covers tleilaxu, and the
former unsupported-effect and copy-list pins were updated to the supported
behaviour rather than re-pinned. Offline suite 7,797/7,797 with typecheck and
lint clean. No game, seat, saved state or deployment changes.

+`game/tleilaxu-ambassador-forces.ts` is now wired into the Ambassador

+
+- one to four physical counters return from the Tanks to reserves, at zero

 ## Physical foundation checkpoint, 7 September 2026
 
 The later `game/tleilaxu-ambassador-forces.ts` helper implements only the resolved physical force quotation. It accepts a beneficiary's faction, reserve/Tanks totals and typed elite inventory, and quotes one through four returned counters with detached before/after custody and the shared elite revival counter. It rejects malformed counts, unavailable ordinary/elite selections, unsupported elite factions and unsafe arithmetic. It uses the minimum necessary elite count when no explicit count is selected; zero returns remain a separate caller choice. Ixian cyborgs retain their distinct uncapped treatment.
 
 Root reviewed the complete helper and its tests. All **11 focused tests pass**, covering all twelve ordinary faction pools, mixed custody conservation, cross-event elite limits, Ixian quantities, invalid selections, safe arithmetic, detached results and independence from private information and RNG. The tests are registered in `npm test`; formatting, lint and full TypeScript checks pass. Root's focused result is `/tmp/dune-tleilaxu-ambassador-forces-root.log`.
 
-This helper is not wired into the engine and does not activate the Ambassador, add player or AI controls, change ordinary revival allowances, choose leader eligibility or pay income. The three material accounting/leader/income questions above are pending user interpretation. The prior Guild checkpoint remains 2,930 passing registered tests plus twenty completed Basic games; these eleven new helper tests are additional focused evidence, not another full-suite or full-expansion run.
