API/TS: Add regression tests and on-the-fly examples for #137

[ryukzak]

Summary

• Add regression tests for duplicate meta key in createResource() when a profile makes meta required (TS Profile: duplicate meta object literal key when meta is a factory param (TS1117) #137)
• Add examples/on-the-fly/ — examples that generate types from registry packages at CI time (gitignored output)
  • kbv-r4/ — German KBV profiles (kbv.ita.for@1.3.1), uses ignorePackageIndex for corrupt package indices
  • norge-r4/ — Norwegian profiles (moved from examples/nodge-r4.ts into proper example structure)
• Add examples/local-package-folder/ PatientMetaRequired profile test
• Add ignorePackageIndex option to APIBuilder (threads to fhir-canonical-manager@0.0.23)
• Refactor APIBuilder options filtering from exclusion-list to explicit pick

CI & scripts cleanup

• Add CI jobs for test-local-package-folder-example and test-on-the-fly-example
• CI workflows now use make targets instead of bun run scripts
• Drop bun-version: latest everywhere (it's the default)
• Flatten single-value matrices in sdk-tests (csharp, python)
• Rename test-python-sdk-test → test-python-sdk (same for fhirpy)
• release.yml: use make test, add --frozen-lockfile
• Remove dead package.json scripts (test:integration, test:performance, test:helpers, codegen, quality, etc.)
• Makefile: rename test-codegen → test, remove format/test-typeschema/test-register targets, lint is now read-only check

Config change

APIBuilder now accepts ignorePackageIndex to bypass corrupt .index.json files:

// before
const builder = new APIBuilder({})

// after — use when a dependency ships a broken .index.json
const builder = new APIBuilder({ ignorePackageIndex: true })
