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.

+## 7 October 2026 — Tleilaxu Ambassador force return wired
+
+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 stage `revival`: 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.
+
+Kept gated exactly as recorded: the printed leader alternative
+(`leaderAlternative: false`), 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; the Tleilaxu special Karama keeps its FAQ-resolved
+Revival-only timing.
+
+Evidence: `tests/tleilaxu-ambassador-engine.test.ts` drives a genuine arrival

+rejection with immutability, the ordinary-only return and the decline path. The
+four-profile `tests/ecaz-entry-bots.test.ts` loop now covers `tleilaxu`, and its

+expectation rather than re-pinned. No game, seat, saved state, deployment,
