feat(linkedin-studio): RE-R3d — temporal overlay (first-mover + saturation) [skip-docs]

R3 slice (b): the rest of hull #3. The morning brief now reads the temporal axis
the R3b seen-log records but the ranking ignored. Two DERIVED signals, computed at
brief time from already-persisted fields (publishedAt/capturedAt -> ageDays,
surfacedCount), never stored:

- first-mover: recent (ageDays <= --first-mover-days, default 2) AND never surfaced
  on a prior day -> ranked up, badge "first ute". Future-dated (ageDays<0) excluded.
- saturation: surfaced on >= --saturation-at (default 3) prior days -> ranked down,
  badge "mettet (Nx)". Self-surfacing (our seen-log), not market coverage.
- warming (1..at-1) keeps the R3b "sett Nx" badge but only at >=2 (contract intact);
  neutral carries no badge.

SB1 derived (no schema bump: SCHEMA_VERSION 4 / BRIEF_SCHEMA_VERSION 1 untouched).
SB2 the R3a relevance composite stays the PRIMARY sort key; the temporal rank is a
new cmp key after pillar-overlap, before effectiveDate -> re-orders only WITHIN a
(composite, overlap) tier. temporalSignal is pure (saturationAt clamped >=1).

Prior-day surfacings exclude today (via lastSurfacedAt), so a same-day re-render is
byte-identical (caught by the R3c run-daily SC7 regression; fixes a latent R3b
prior-day imprecision too). brief CLI gains --first-mover-days / --saturation-at;
schedule untouched (nightly uses defaults).

Wiring: trend-spotter.md (prose), trend-scoring-modes.md (one-line consumer note),
README (## Temporal overlay), gate Section 16m (+6 unconditional -> ASSERT floor
111->117), TRENDS_TESTS_FLOOR 192->216. Counts 29/19/27 unchanged. Zero new files.

Gate: Passed 132 / Failed 0; trends 216/216; hook suite 139/139 untouched.

The brief also applies a **derived temporal overlay** (RE-R3d): within a relevance tier, a fresh,
not-yet-surfaced trend is ranked up as a **first-mover** (`· 🥇 først ute`) and a repeatedly-surfaced
one is ranked down as **saturated** (`· 🔁 mettet`) — computed at render time from the publish/capture
dates + the seen-log, with no new capture step. Tune with `--first-mover-days N` / `--saturation-at N`.
The morning brief can also be **scheduled** to regenerate autonomously each morning — deterministic,
from the current store — via `src/cli.ts schedule` (print-first: it emits a launchd/cron entry firing
the `run-daily.sh` headless wrapper). That nightly run re-renders the brief only; your polling above

before the brief) plugs into the documented seam in `run-daily.sh` as a later slice (e); a
brief-history diff is also a later slice.
## Temporal overlay (RE-R3d)
The brief applies a **derived temporal overlay** when it ranks — two signals computed at render time
from already-persisted fields (`publishedAt`/`capturedAt` → age, `surfacedCount` → self-exposure), so
**nothing new is stored** (`SCHEMA_VERSION` stays 4) and the signal can never go stale:
- **first-mover** — recent (`ageDays ≤ --first-mover-days`, default **2**) AND never surfaced on a
prior day. Ranked up; badge `· 🥇 først ute`. A future-dated trend (`ageDays < 0`) is excluded.
- **saturation** — surfaced on `≥ --saturation-at` (default **3**) prior distinct days. Ranked down;
badge `· 🔁 mettet (Nx)`. This is **self-surfacing** ("you keep seeing this") from OUR seen-log — not
market coverage (that needs external polling, a later slice).
- **warming** (surfaced 1..at-1) keeps the RE-R3b `· sett Nx` badge, but **only at ≥2** (that badge
contract is unchanged); **neutral** (no exposure signal) carries no badge.
Ranking integration: the relevance composite (RE-R3a) stays the **primary** sort key; the temporal
rank (first-mover↑ / saturated↓) is a new key inserted **after** pillar-overlap and **before** the
`effectiveDate` recency tiebreaker — so the overlay only re-orders *within* a (composite, overlap)
tier, never overriding relevance. Prior-day surfacings exclude today (via `lastSurfacedAt`), so a
same-day re-render is byte-identical. Tune per run with `--first-mover-days N` / `--saturation-at N`
(the scheduled nightly run uses the defaults).
