ci: tiered fail-fast pipeline — stop waiting 20min for already-failed CI

+# CI Orchestrator — tiered fail-fast pipeline
+#
+# Calls the per-crate workflows in dependency tiers so that a failure in a
+# leaf crate (tier 0) cancels all downstream jobs immediately instead of
+# letting 18 jobs run for 20 minutes.
+#
+# Tier structure follows the Cargo workspace dependency graph:
+#
+#   Tier 0 (leaf crates):    models, core, boundary
+#   Tier 1 (substrate):      compute, compute-cuda, compute-vulkan
+#   Tier 2 (engine):         inference, vindex
+#   Tier 3 (API layer):      kv, lql
+#   Tier 4 (applications):   server, cli, shannon-verify
+#
+# Within each tier, all jobs run in parallel. A failure in any tier skips
+# all subsequent tiers. Coverage jobs (where present) run in the same tier
+# as their crate's test job via needs.
+#
+# The per-crate workflows still retain their own push/PR triggers with path
+# filters, so a change touching only one crate still runs just that one
+# workflow without the full pipeline. This orchestrator fires on every PR
+# and on every push to main to provide the fail-fast gate.
