### Problem
Two settings that already exist in the `Settings` schema and are honored
by the engine have **no control anywhere in the dashboard UI**:
- `buildTimeoutMs` — max time for build/verification commands (default
`300000` = 5 min)
- `insightExtractionEnabled` (+ `insightExtractionSchedule`) — periodic
extraction of durable insights from completed tasks into memory
Because there's no UI, the only way to change them is to hand-edit
`config.json` — but that has to be done with the app fully closed, since
the running app rewrites `config.json` from its database on
reload/shutdown and silently clobbers live file edits. That's a
confusing footgun (edits appear to "not stick"), and 5 minutes is too
low a build timeout for large monorepo / Docker builds.
### Change
Expose both via controls that mirror the existing patterns in the same
sections — no schema, route, or persistence changes needed (the keys
already flow through `form`/`setForm` → `updateSettings`).
- **Scheduling section:** "Build/Verification Timeout (minutes)", placed
next to the existing "Stuck Task Timeout (minutes)", using the same
minutes↔ms conversion.
- **Memory section:** "Enable Insight Extraction" checkbox + conditional
cron "Schedule" field, placed next to the existing Auto-Summarize
controls (matching how `insightExtractionSchedule` is already documented
in `types.ts`).
Both use the existing `t(...)` i18n fallback style used throughout these
sections.
### Scope note (feedback welcome)
Both live in their existing **project-scoped** sections (Scheduling,
Memory), which is the natural home. If maintainers want these settable
as **global/user defaults** too, I'm happy to add a global-defaults
counterpart in a follow-up — just wanted to keep this PR focused and
non-duplicative.
### Testing
- Both keys are pre-existing fields on the `Settings` type
(`buildTimeoutMs?: number` at `packages/core/src/types.ts`;
`insightExtractionEnabled?`/`insightExtractionSchedule?` likewise), so
the additions are type-safe.
- Controls follow the exact JSX/handler pattern of adjacent fields
already in each section.
