Addresses #801

This pull request moves the project from TypeScript 5.9 to TypeScript 6.0.3 by updating the devDependency, the pnpm workspace override and the peer dependency range (^5.9.3 || ^6.0.0), and by making the new TypeScript 6 compiler defaults explicit in tsconfig.json. TypeScript 7 was attempted and reverted, because vue-tsc 3.3.x and @arethetypeswrong/core 0.18.5 require the TypeScript JS API, which 7.0 does not ship. Type checking, the tsdown build (including attw and publint) and all 11 vitest tests pass on TypeScript 6. Reviewers should note three things: libReplacement is set to the new default false rather than the previous true; the regenerated lockfile also bumps the pinned Node runtime to 24.22.1, which is unrelated and should ideally be reverted; and pnpm lint was not run.

Note: this touches files also modified in #772 (v1.0.4), #794 (chore(deps): update all non-major dependencies), #799 (chore(deps): lock file maintenance), #803 (chore(deps): update nuxt framework to ~4.6.2), #804 (chore(deps): update peerdependency @nuxt/cli to v4); this PR is based on current main and is independent of them.

• Static integrity checks (L1): no findings.
• Test files changed: none.
• Independent model review (L2): mergeable, confidence 0.74; 0 blocking, 5 warnings, 2 info.

Behavior changes

• The typescript peer dependency range is widened from ^5.9.3 to ^5.9.3 || ^6.0.0, so consumers can now install the package alongside TypeScript 6 without peer warnings.
• The development toolchain now compiles and type-checks with TypeScript 6.0.3 instead of 5.9.x (devDependency and pnpm workspace override).
• The lockfile's pinned Node.js runtime moved from 24.21.0 to 24.22.1 as a side effect of regenerating the lockfile.
• The published JS and declaration output is reported to be identical apart from content-hash filenames and the embedded package.json TypeScript ranges.
• No runtime API, CLI behaviour or emitted type changes were found beyond the above.

Test changes

No test files were changed. The only verification-related file touched is tsconfig.json. In it, the new TypeScript 6 defaults (types, rootDir, noUncheckedSideEffectImports, libReplacement) were set explicitly. None of these loosens checking: types: ["node"] narrows globals, and noUncheckedSideEffectImports: false keeps the previous behaviour. libReplacement: false matches the new default rather than the old one, which only matters if @typescript/lib-* packages are installed. All 11 tests pass before and after the change. Lint was not run.

Closing this: unbuild doesn't support TypeScript 6 yet, so widening the peer range can't pass test:engines today. I'm testing a migration tool and the description was generated with it — sorry for the noise, and thanks for the clear contribution rules.
