chore(ci): apply L1-L5 CI-speedup pattern (via scitex-dev CLI)

+# Consolidated PR-only CI gate. Runs the per-PR validation suite as a
+# single workflow so the cancel-in-progress concurrency group, path
+# filters, and uv cache apply uniformly. Post-merge validation lives
+# in release-ci.yml.
+#
+# L1 concurrency — cancel superseded PR runs.
+# L3 path filters — skip docs/skills/examples/markdown-only PRs.
+# L4 conditional matrix — full ["3.11", "3.12", "3.13"] on PR (this trigger).
+# L5a uv-managed Python (`uv python install` + `uv venv --python`) so the
+#     matrix leg is not bound to the runner's system Python.
+# L5b .venv/bin on PATH (and explicit `.venv/bin/python` for clarity) so
+#     console scripts resolve without needing `uv run`.
