Subject: [PATCH] Bump typescript from 5.9.3 to 6.0.3

Supersedes #424, which bumped straight to TypeScript 7.0.2. That cannot
land yet: typescript-eslint has no TS 7 support and is blocked upstream
until the native Go compiler ships a public API
(typescript-eslint/typescript-eslint#10940), so `npm run lint` crashes in
ts-api-utils. TypeScript 6 is the last JS-based compiler and sits inside
typescript-eslint's `<6.1.0` peer range.

TypeScript 6 turns several tsconfig options into deprecation errors and
drops automatic `@types` inclusion, so the config needs three changes:

- `baseUrl` is deprecated and removed in 7.0; `rootDir` replaces it and
  has to be explicit once `baseUrl` is gone
- `paths` values must be relative in 7.0
- `types: ["chrome"]` restores the `chrome` globals, which 5.9 picked up
  by scanning all of node_modules/@types

Also refreshes @types/node 24.0.8 -> 26.1.2 in the lockfile. 24.0.8
declares `URLPattern` incompatibly with TypeScript 6's lib.dom.d.ts,
which this project sees because it sets `skipLibCheck: false`.
@types/tape already requests `@types/node: "*"`, so no direct dependency
is needed.

The emitted `distribution/` is byte-identical to the 5.9.3 output across
all 108 files, so the published API is unchanged.
