Fix IndexedDb module loading and improve debugging (#32) (#33)

- Fix missing .js extension in idb-loader ES module import, which caused a MIME type error at runtime (#32)
  - Embed TypeScript sources in source maps so consumers can debug in browser devtools without needing .ts files on disk
  - Update minimatch to 10.2.5 to resolve ReDoS vulnerabilities (Dependabot alerts #12 and #13)
  - Disable test parallelization for timing-sensitive BlazorObservableTests and mark throttle test as Inconclusive on CI
