Blocked: TypeScript 7 breaks npm run build

The ESM bundle still builds, but the declaration step crashes:

$ npm run build
ESM ⚡️ Build success in 45ms

node:internal/event_target:1118
TypeError: Cannot read properties of undefined (reading 'useCaseSensitiveFileNames')
    at rollup-plugin-dts@6.1.1_..._typescript@5.7.3/.../rollup-plugin-dts.cjs
    at .../node_modules/tsup/dist/rollup.js:4857:37

tsup 8.5.1 generates --dts output through a bundled rollup-plugin-dts@6.1.1, which drives the TS compiler API directly. TS 7.0 (the native port) reshaped that API surface, so the plugin gets an undefined host back.

Isolated to typescript alone — on this exact branch head (3ba23105), with every other dependency untouched and only typescript reverted:

typescript	npm run build
7.0.2 (this PR)	✗ TypeError: ... useCaseSensitiveFileNames
6.0.3 (main)	✓ DTS ⚡️ Build success in 2300ms

Why CI is green

There is no build job. The checks on this PR are Format, Lint, Test (Node 24), commitlint, renovate/stability-days — nothing runs tsup. Since prepublishOnly is npm run build, this would surface at publish time, breaking a release rather than a PR.

Lint and Format do pass on TS 7 (oxlint/dprint don't use the TS compiler), so those greens aren't evidence either way.

Path forward

Hold until tsup ships a rollup-plugin-dts that supports TS 7 (upstream tracking: rollup-plugin-dts needs a TS 7 compatible release; tsup then needs to pick it up). Nothing to change in this repo. Note the shipped JS output is unaffected — it's only declaration generation — so if the .d.ts files ever became optional this could be revisited, but exports currently ships dist/index.d.ts.

Suggest a Renovate hold on typescript majors for this repo until then, so this doesn't get re-proposed each cycle.
