fix(site-api): Prism overview agents and G2 are v2.1 only

[echobt]

Summary

• GET /v1/site/arenas/prism no longer counts closed 2.0 harvests. agents and bestScore require prism-v2.1 / recipe 2.1.x / scoring generation 21; empty + — is the honest wait (uid-0 burn is a weights fact, not a score).
• bestScore is G2 (higher better), labeled BEST G2.

Companion frontend: fix/prism-dash-overview.

Test plan

• cargo test -p site-data prism_arena and cargo test -p site-api arenas_and_design
• After deploy, GET /v1/site/arenas/prism shows bestScoreLabel: BEST G2 and does not inflate agents from 2.0 rows

Summary by CodeRabbit

• Bug Fixes
  • Improved Prism arena results by excluding legacy entries from miner counts and best-score calculations.
  • Best scores now reflect valid, positive completed submissions and display consistently as G2 values.
  • Added safeguards to prevent incomplete or outdated data from affecting arena summaries.

📝 Walkthrough

Walkthrough

The PR updates Prism arena aggregation to use v2.1 eligibility and positive G2 scores. It adds helper functions and regression assertions. No production changes occur in the site API handler.

Changes

Prism v2.1 aggregation

Layer / File(s)	Summary
Eligibility and score aggregation crates/site-data/src/map.rs	Prism mapping detects v2.1 metadata, excludes legacy rows, counts distinct eligible miners, and selects the highest positive G2 score.
Regression validation crates/site-data/src/map.rs, crates/site-api/src/handlers.rs	Tests verify legacy exclusion, v2.1 score selection, and the expected Prism arena response values.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 78502

The API can still count legacy or incompletely marked records as v2.1, inflating the reported agent count and BEST G2 score. Merge should wait until all required markers are validated together and malformed recipe versions are rejected.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Require all valid v2.1 markers before counting a row.

Lines 323-328 use ||, so a row with only one marker is eligible. This conflicts with the required conjunction of prism-v2.1, a 2.1.x recipe, and scoring generation 21. Lines 373-377 also accept values such as 2.1 or 2.1.invalid.

A legacy row with one stale marker can inflate agents or bestScore. Make the three checks conjunctive and reject incomplete or malformed recipe versions. Update the regression so v21 contains all three markers and the generation-only inflight row is excluded.

Proposed eligibility change

-    contest_id_is_v21(root)
-        || contest_id_is_v21(metrics)
-        || scoring_gen_is_21(root)
-        || scoring_gen_is_21(metrics)
-        || recipe_is_v21(root)
-        || recipe_is_v21(metrics)
+    (contest_id_is_v21(root) || contest_id_is_v21(metrics))
+        && (scoring_gen_is_21(root) || scoring_gen_is_21(metrics))
+        && (recipe_is_v21(root) || recipe_is_v21(metrics))
