chore: adopt TypeScript 7, extend type-check coverage, align versions

[dmythro]

Summary

Upgrades TypeScript 6.0.3 → 7.0.2 and fixes the fallout the bump exposed, plus some version/tooling alignment.

TS 7 removed the baseUrl option, and its stricter rootDir handling surfaced errors that were previously masked — errors in packages that CI never type-checked. So the upgrade comes with real fixes, not just a version number.

Changes

TypeScript 7 + type-check coverage

• Drop baseUrl (removed in TS 7) and the dead outDir from the shared packages/tsconfig/tsconfig.json, keeping the shared base runtime-neutral.
• Declare types: ["node", "bun"] in the scripts and test-js configs — the consumers that actually target those runtimes — so node/Bun globals resolve, rather than injecting them from the shared base.
• Remove the now-invalid baseUrl from packages/scripts/tsconfig.json.
• Add the with { type: "json" } import attribute required under NodeNext (countries.emoji.ts).
• Extend check-types to cover the scripts and test-js packages — previously only the countries package was type-checked in CI; the others were checked solely by the IDE, where a rootDir error masked genuine failures.

Version / tooling alignment

• Bump the root workspace version 3.2.0 → 3.4.0 to match the released package, and update the version script so it keeps the root in sync going forward.
• Set packageManager to bun@1.3.14.

Verification

• bun run ci — lint + check-types (all 3 packages) + build + test: pass (16 tests)
• Build produces no dist/ changes
• Local CodeRabbit review: 0 findings

📝 Walkthrough

Walkthrough

The root package version changes to 3.4.0, with updated Bun and TypeScript versions and expanded type-checking coverage. TypeScript configurations remove baseUrl and outDir, add Bun types, and retain NodeNext settings. The countries emoji data import uses a JSON import attribute. The version script now updates the root package.json alongside existing generated package files.

Poem

I’m a rabbit with config in flight,
Hopping through versions crisp and bright.
Bun bells ring, TypeScript grows,
JSON wears a proper coat of clothes.
The root package joins the dance—
Squeak hooray for version advance!

Keep Node/Bun globals out of the shared browser configuration.

packages/test-js/tsconfig.json extends this file and includes DOM libraries, so these entries expose server-runtime globals to browser-oriented typechecks. Move them to the Node/Bun-specific configuration unless every consumer is intentionally targeting those runtimes.
