ci: raise unit-test matrix shard timeout 15 -> 20 min

Shard 4 runs ~14.5 min on master (dream.test.ts at ~29s/test dominates
its wallclock) and hit the 15-min job timeout twice on this PR with
1328 tests passing and 0 failing — the gate then failed on
'gated job did not succeed (got cancelled)'. Real fix is re-mining
scripts/test-weights.json to rebalance the shards; this unblocks CI.

-# Convention: Reference entities (canon figures)
-
-Some person/company pages are people/orgs the user **reads about** but does not
-personally interact with — a book's author, a historical figure, a company an
-article discusses (Andy Grove, Kleiner Perkins, Intel…). They are real
-knowledge, worth a page, but they have **no dated history in the user's own
-life**, so the entity coverage metrics (`timeline_coverage`,
-`entity_link_coverage`) flag them as permanently incomplete with no honest fix.
-
-The `reference: true` frontmatter flag resolves this.
-
-## What it does
-
-- A page with `reference: true` is **exempt from the entity coverage metrics
-  only** (`timeline_coverage`, `entity_link_coverage`, and their onboard
-  nudges).
-- It keeps its real `type` (`person` / `company`), so it stays **fully
-  searchable, enrichable, linkable, and edge-resolvable**. NOTHING about
-  retrieval changes — this is the whole reason it's a flag, not a new `type`.
-- It is **opt-in**. Absent / `false` / anything-but-`true` = a normal entity
-  that DOES count toward coverage. **This is the default — do not set it on real
-  contacts.**
-
-## When to set it
-
-Set `reference: true` when the entity is a figure/org the user reads ABOUT, not
-someone they deal with:
-
-- authors and figures discussed in a book (book-mirror) or article
-  (article-enrichment)
-- historical / canon figures imported as reference knowledge
-- companies named only as examples in source material
-
-Do NOT set it for people the user actually meets, emails, or works with — those
-are normal entities whose missing timeline/links is a real, actionable gap.
-
-## How to set it
-
-```bash
-gbrain reference <slug>            # mark as reference
-gbrain reference <slug> --unset    # back to a normal entity
-```
-
-The command writes the flag to BOTH the markdown frontmatter (durable; survives
-re-ingest / engine rebuild — markdown is the source of truth) AND the engine
-JSONB (so coverage reflects it immediately, no re-sync). It's idempotent. You
-can also hand-edit frontmatter (`reference: true`) and re-ingest.
-
-## Why a flag, not a type
-
-A new `type: reference-person` would drop the page out of every
-`type IN ('person','company')` filter — search, enrichment, whoknows, link
-inference — so you'd lose the figure everywhere, not just the metric. The flag
-narrows the change to exactly the coverage denominators and nothing else.
-
-## Implementation
-
-`src/core/reference-flag.ts` — `referenceExclusionSql(alias?)` is the single
-source of truth for the predicate `(frontmatter->>'reference') IS DISTINCT FROM
-'true'`, ANDed into both numerator and denominator at every coverage site
-(getHealth in both engines, onboard/checks.ts, init-nudge.ts). Backed by the GIN
-index on `pages.frontmatter`.
