chore(db): purge run 29912027293 — accidental ingest (#616)

Add GitHub Actions run 29912027293 (e2e Test -
dsv4-fp4-mi355x-sglang-disagg-agentic-hicache, branch
amd/agentx-v1.0-th-hicon-dpa) to PURGED_RUNS.

It was accidentally ingested while testing and is currently the sole
run backing the DeepSeek-V4-Pro / MI355X / mori-sglang / FP4 / disagg /
agentic_traces / offload=on line on the dashboard (conc 48/64/96/128,
benchmark_results 436604-436607). On merge, apply-run-overrides.yml
deletes the run's rows (benchmarks, agentic trace-replay sidecars,
availability) from production, verifies the DB, and refreshes the cache.
The entry also skips the run on any future re-ingest.
