ci(audience): trim playmode PR to 8 cells, add weekly 12-cell run (SDK-327)

[ImmutableJeffrey]

Summary

• Trims playmode PR matrix from 12 to 8 cells; drops Unity 2022.3.62f2 from PR runs.
• Adds on: schedule (Sat 14:00 UTC = Sun 00:00 Sydney AEST in winter, Sun 01:00 AEDT in summer) so the full 12-cell matrix runs weekly on the default branch.
• workflow_dispatch continues to fire the full matrix on demand.
• Restructures the playmode matrix from a flat 12-entry include list to cross-product axes (unity x target x backend) plus include entries that supply changeset by unity and runner by target.
• matrix.exclude is set conditionally via fromJSON, so only PR runs drop the 2022 cells. Single job, no duplicated steps.
• Tidies the mobile-build matrix to the same cross-product shape (target x unity, method added by target via include). Same 6 cells, same behaviour.

Linear: SDK-327

Note

Medium Risk
Changes CI matrix logic and trigger conditions, which could unintentionally reduce test coverage on PRs or misconfigure scheduled runs if the matrix/exclude expressions are wrong.

Overview
Adds a weekly schedule trigger to run the full PlayMode test matrix on the default branch, while keeping workflow_dispatch for on-demand full runs.

Restructures the PlayMode matrix into cross-product axes (unity/target/backend) with include entries for changeset and per-target runners, and conditionally excludes Unity 2022.3.62f2 on pull_request to trim PR runs.

Simplifies the mobile-build job matrix to the same cross-product shape (target × unity) while preserving the same build methods and overall behavior.

mobile-build if not updated for new schedule trigger

Low Severity

The playmode job's if was explicitly updated to handle the new schedule event, but the mobile-build job's if was not. On schedule events, github.event.pull_request.head.repo.fork is null, and GitHub Actions coerces null == false to true (both become 0), so mobile-build silently runs every week. If this is intended, the condition is fragile and inconsistent with the playmode guard; if unintended, it wastes six extra CI cells weekly.
