Bumps typescript from ~5.9.3 to the 7.0.1-rc native (Go) compiler.
TypeScript 7.0 removes the `baseUrl` option (hard error TS5102). It is set
in three places here: our root tsconfig, the theme package tsconfig, and
@docusaurus/tsconfig (the upstream base we extend). Since an inherited
option can't be unset via `extends`, the base config is patched (pnpm
patch) to drop `baseUrl` + `paths`, and `paths: { "@site/*": ["./*"] }` is
re-declared locally in the root config where the alias is used.
Validation:
- pnpm build (CI gate): passes
- pnpm format:check / sidebar:check: pass
- tsc: 0 TS5102 errors; @site/* resolves
- changelog-generator tsc emit: 0 errors
The patch is a temporary bridge until @docusaurus/tsconfig ships without
baseUrl; remove patches/ and the patchedDependencies entry at that point.

typescript@7.0.1-rcis a release candidate. No stable programmatic API ships until 7.1; nothing here consumes the TS API.
