fix(deps): hold typescript below 7 until typescript-eslint supports it

[vpetersson-bot]

Problem

The weekly npm group PR (#84) is red on all four jobs — Build, Format, Lint and Test. They all fail at the same place, npm ci:

npm error code ERESOLVE
npm error While resolving: typescript-eslint@8.69.0
npm error Found: typescript@7.0.2
npm error   typescript@"^7.0.2" from the root project

Cause

typescript-eslint has no released version that supports TypeScript 7. Every published version up to and including the current 8.70.0 declares:

"peerDependencies": { "typescript": ">=4.8.4 <6.1.0" }

So bumping typescript-eslint does not help — the group simply cannot take typescript 7 yet. Install fails, and every job downstream of it fails with it.

For the record, the runtime symptom if you force the install past npm is TypeError: Cannot read properties of undefined (reading 'Cjs') in @typescript-eslint/typescript-estree — TypeScript 7 no longer exposes Extension on its public API.

Fix

Have Dependabot hold typescript below 7 until typescript-eslint supports it. The rest of the group keeps flowing, including typescript 6.

Verification

Checked out #84 locally with typescript dropped to ^6.0.3 and every other update in the group kept:

tsc --noEmit   ✓
eslint .       ✓

One follow-up, not fixed here

Once the install is unblocked, the Format job will still fail. Prettier 3.9.6 (also in this group) reformats one union type in src/utils/calendar.ts:

 type CalendarViewElement =
-  | WeeklyCalendarView
-  | DailyCalendarView
-  | ScheduleCalendarView
+  WeeklyCalendarView | DailyCalendarView | ScheduleCalendarView

That reformat has to land in the same commit as the Prettier bump — 3.8.1 and 3.9.6 reject each other's output, so committing it here would turn main red instead. Run npm run format inside the regenerated group PR.

After merging

Comment @dependabot recreate on #84 — it will come back without the typescript bump.

The same TypeScript 7 breakage affects all 17 Screenly edge apps; an equivalent change is going up in each.

Duplicate of #85, which already proposes the same fix. Closing this one in favour of the earlier PR.
