Lands the TypeScript 5.9.3 → 6.0.3 major bump from #76 together with the build fix it needs.

Problem: TS 6 promotes the deprecated baseUrl option to a hard error (TS5101) in the tsup DTS build, so #76 failed Build & Validate Package (and would have blocked release). We don't set baseUrl ourselves — it's injected by the dts tooling.

Fix: add "ignoreDeprecations": "6.0" to tsconfig.json (the compiler's own recommended, side-effect-free remedy). Revisit at the TS 7 upgrade.

Verified locally: lint clean, build (incl. DTS) succeeds, 1573 tests pass / 3 skipped on TS 6.0.3.

Supersedes #76 (close that one on merge).

…recation

TypeScript 6 promotes the deprecated baseUrl option to a hard error (TS5101) in
the tsup DTS build, breaking the package build. We don't set baseUrl ourselves
(it is injected by the dts tooling), so add ignoreDeprecations: "6.0" to
tsconfig.json — the compiler's own recommended, side-effect-free remedy. Build,
lint, and the full test suite are green on TS 6.0.3.

Supersedes #76.
