Fix TypeScript tsconfig context resolution

[subsetpark]

Summary

• pass the tsconfig path into TypeScript config parsing so compiler options retain configFilePath
• add a TypeScript adapter fixture that resolves package-local @types from the analyzed repo instead of the archlint cwd

Validation

• sh typescript/test.sh
• uv run --project . python evaluate_test.py
• uv run --project /Users/zax/code-src/archlint python /Users/zax/code-src/archlint/evaluate.py --repo-root /Users/zax/code-src/provisioning-agent --adapter typescript --typescript-root packages/agent-kernel now reaches policy evaluation instead of failing on TS2688 for bun types
