Do not pick up before a trigger condition fires.
As a maintainer, I want the toolchain on TypeScript 7 so that the project stays on a supported major and gains the native compiler's speed.
What
Bump typescript from ~6.0.x to ^7 and reconcile the toolchain.
Why
Dependabot #1407 (typescript 6.0.3 -> 7.0.2) is blocked: npm ci fails with ERESOLVE because @astrojs/check (provides astro check, our type + content-schema gate) peers typescript@"^5.0.0 || ^6.0.0". No published @astrojs/check version accepts TS 7 (latest 0.9.9 as of 2026-07-18). Forcing with --legacy-peer-deps would risk breaking the validation gate.
Trigger conditions (pick up when any fires)
@astrojs/check publishes a version whose typescript peer range includes ^7.- We decide to drop
astro check from the quality gate (would need its own ADR).
Acceptance criteria
Do not pick up before a trigger condition fires.
