- Add migration 14: partial covering indexes WHERE job_state='running' for user/project/subcluster groupings (tiny B-tree vs full table) - Inline literal state value in BuildWhereClause so SQLite matches partial indexes instead of parameterized placeholders - Add per-request statsGroupCache (sync.Once per filter+groupBy key) so identical grouped stats queries execute only once per GQL operation - Parallelize 4 histogram queries in AddHistograms using errgroup - Consolidate frontend from 6 GQL aliases to 2, sort+slice top-10 client-side via $derived Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Entire-Checkpoint: 5b26a6e5ff10

-- Migration 14: Partial covering indexes for running jobs
|
|
-- Only running jobs are in the B-tree, so these indexes are tiny compared to
|
|
-- the full-table indexes from migration 13. SQLite uses them when the query
|
|
-- contains the literal `job_state = 'running'` (not a parameter placeholder).
