The /explain endpoint blocked on a synchronous NIM call (llama-3.3-70b,
30-60s+) while nginx's default 60s proxy-read-timeout fired first,
surfacing every AI request as a 504 Gateway Timeout.
Switch the NIM proxy to streaming (stream:true) and relay its SSE to the
browser via a new _emit() helper; the client now reads resp.body
incrementally and renders tokens as they arrive. With chunks flowing,
nginx's read-timeout resets per chunk so the 60s wall is gone, and the
frozen spinner is replaced by live text.
Ingress: disable proxy-buffering (else nginx buffers the whole response,
defeating streaming) and set proxy-read-timeout to 120s as the
inter-chunk gap budget. Server urlopen timeout 60->110s.

Adds three new CronJobs (spark-accuracy-blunder, spark-clock-pressure,
spark-smurf-anomaly) and registers their six output tables in the
analytics webview (accuracy_by_rating, blunder_outcome, clock_by_rating,
scramble_outcome, smurf_anomaly, flagged_smurfs).

Points to /spark-output/.pgn-cache so the decompressed Lichess PGN file
is written to the shared PVC, accessible by both driver and executor pods.

- Rewrite webview serve.py to query PostgreSQL analytics tables via psycopg2
instead of reading CSV files from PVC; PVC mount removed from Deployment
- Remove isPgnMode guard from all 4 original jobs so results always write to DB
regardless of whether input comes from game_records or a Lichess PGN dump
- Add JDBC write-back to all 7 new analytics jobs (game_length_distribution,
game_length_by_result, color_advantage, elo_distribution, time_control_stats,
hourly_activity, weekly_activity, rating_mismatch, termination_stats)
- Add analytics_component_sizes JDBC write to PlayerGraphJob
- Add NOWCHESS_PGN_PATH staging patches for the 7 new CronJobs

Adds CronJobs and headless driver Services for GameLengthJob, ColorAdvantageJob,
EloDistributionJob, TimeControlJob, DailyActivityJob, RatingMismatchJob, and
TerminationStatsJob. All suspended by default; scheduled Saturday mornings.
Adds spark-analytics-webview: a stdlib Python HTTP server (ConfigMap + Deployment
+ Service) that reads CSV output from the spark-analytics-output PVC and renders
13 datasets as browsable HTML tables. Disabled (replicas=0) in base.
Staging overlay enables the webview (replicas=1), exposes it via Ingress at
spark-results-st.nowchess.janis-eccarius.de, and sets NOWCHESS_PGN_PATH on all
CronJobs to the Lichess Jan-2013 rated standard PGN dump for demo runs without
a NowChess database.
