Upgrade the compiler from TypeScript 5.9.3 to 6.0.3 instead of 7.x. TypeScript 7 conflicts with the current ts-jest peer range; 6.0.3 stays within the supported range and keeps @types/node at 22.20.2 for the minimum supported Node runtime.

Remove unused baseUrl. Retain the current module-resolution/output layout with TypeScript 6's explicit ignoreDeprecations setting, also on the intentional legacy CommonJS consumer check. Limit Dependabot proposals to TypeScript <7 and Node types <23, matching the chosen support policy. No parser source or runtime dependency changes.

Validation:

  • npm installation succeeds without force/legacy-peer-deps; audit reports zero known vulnerabilities.
  • Build, Biome and package type-resolution checker pass.
  • 519 Jest tests pass on Node and actual Bun; smoke passes on Node/Bun/Deno.
  • Fresh packed consumer type fixtures pass under TypeScript 6 in NodeNext ESM/CJS and legacy CommonJS modes.
  • Compared compiler output with 5.9.3: all 44 JavaScript files and all 44 declaration files across CJS/ESM are byte-for-byte identical.

PR #63 was closed per the decision to keep Node 22 types. The independent ts-jest patch update in #62 remains compatible; neither its old nor new version supports TypeScript 7.

All remote checks now pass: Node 22/24, Bun, Deno, CodeQL (JavaScript/TypeScript and Actions), and Dependabot configuration validation.

Bumps [typescript](https://github.com/microsoft/TypeScript) from 5.9.3 to 7.0.2.
