ci(nests): drop hang-interop job from build.yml

Per maintainer ask: keep the cross-stack interop suite out of CI
for now. The full HangInteropTest suite shows ~33% flake on
late_join_listener_still_decodes_tail (catalog-cancelled race
between the speaker's setOnNewSubscriber hook and the listener's
catalog subscribe-bidi) that the per-method resetShared() fix
doesn't fully resolve. CI'ing a flaky suite is net-negative.

Suite still runs locally via -DnestsHangInterop=true. Results plan
updated to reflect the 'not wired' status with a re-evaluation
trigger (root-cause the late-join flake first).

# Cross-stack interop tests (T16). Builds the Rust hang-listen +
# hang-publish sidecars (nestsClient/tests/hang-interop/), `cargo install`s
# moq-relay + moq-token-cli at the version pinned in

# Linux-only: the cargo install of `moq-relay` 0.10.x has nontrivial
# native deps (aws-lc-sys, ring) that take 5+ min cold; we cache
# both ~/.cargo and the nestsClient/tests/hang-interop/target tree so the warm
# path is a few seconds. macOS / Windows runs would double the
# matrix cost without catching anything Linux doesn't catch — the
# protocol logic is platform-agnostic and the JNA libopus natives
# are already exercised by the unit-level JvmOpusRoundTripTest on
# the Android job.

## CI integration
`.github/workflows/build.yml` now has a `hang-interop` job:
**Not wired.** Intentionally kept out of `.github/workflows/build.yml`
for now — the full suite shows ~33% flake on
`late_join_listener_still_decodes_tail` (catalog cancelled, race
between speaker's `setOnNewSubscriber` hook and the listener's
catalog subscribe-bidi) that the per-method `resetShared()` fix
doesn't fully resolve. Wiring CI on a flaky suite would burn
maintainer time on false reds.
- Linux-only (Rust toolchain + libopus available out of the box)
- Caches `~/.cargo` and `~/.cache/amethyst-nests-interop/` between
runs so `cargo install moq-relay` and the workspace `cargo build`
are warm on the second run
- Runs `:nestsClient:jvmTest -DnestsHangInterop=true`
- Depends on the existing `lint` job (only runs after spotless +
ktlint pass)
The suite runs locally via `-DnestsHangInterop=true` and is
documented as the regression bar for any future MoQ wire-format
or moq-lite session-cycle changes. Re-evaluate CI gating after the
late-join flake's root cause lands.
Browser interop will land its own job once `feat/nests-browser-interop`
merges; that job adds `bun install` + Playwright Chromium caching.
Browser interop (`feat/nests-browser-interop`) follows the same
"locally only via `-DnestsBrowserInterop=true`" rule pending its own
flake assessment.
