feat(flags): add seed flags for 6 missing products + 6 new evaluator edge-case tests
- seed.ts: add default flags for jarvisjr (3), peakpulse (3), flowmonk (2), notelett (2), actiontrail (2), localmemgpt (2)
Previously only chronomind, nomgap, mindlyst, smartauth, lysnrai had seed flags — common flags (maintenance_mode, telemetry_enabled) were not seeded for newer products
- flags.test.ts: 63 → 69 tests (+6):
- anonymous user with partial percentage returns off
- partial rule rollout (0%) skips even matching users
- neq operator (not equal)
- contains operator
- gte + lt numeric range on custom attributes
- missing context attribute returns off
