Add best-effort CDS extractor support for @sap/cds-indexer

[data-douser]

What This PR Contributes

Summary of Changes

• Integrate indexer orchestration into cds-extractor.ts between dependency installation and compilation phases
• New src/cds/indexer.ts: detect projects using @sap/cds-indexer and run npx --yes @sap/cds-indexer before compilation, with graceful error handling and diagnostic warnings on failure
• Include @sap/cds-indexer in dependency cache when declared in project package.json (dependencies or devDependencies)
• Add addCdsIndexerDiagnostic() to diagnostics.ts
• Add unit tests to cover new indexer and diagnostic functions
• Fix Jest localstorage-file warnings on Node.js v25+

Outline of Changes

CDS Extraction Pipeline Enhancements

• Added orchestration of the CDS indexer (orchestrateCdsIndexer) to run before compilation in cds-extractor.ts, with performance tracking and summary logging. This ensures that projects requiring indexing are processed appropriately. [1] [2]

Testing Environment Improvements

• Updated jest.config.js to suppress Node.js v25+ localStorage warnings by setting the --localstorage-file option for all Jest worker processes. This prevents noisy warnings during test runs on newer Node versions.

Dependency Updates

• Upgraded the @typescript-eslint suite (including eslint-plugin, parser, scope-manager, type-utils, utils, visitor-keys, etc.) from version 8.55.0 to 8.56.0, and updated peer dependencies to support ESLint v10. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12]
• Upgraded eslint-plugin-jest from 29.14.0 to 29.15.0.
• Updated eslint-visitor-keys from 4.2.1 to 5.0.0, which also updates its required Node.js engine version.

Miscellaneous Package Lock Cleanups

• Removed "peer": true fields from several dependencies in package-lock.json, reflecting changes in how peer dependencies are tracked or resolved. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Pull request overview

This PR adds best-effort support for running @sap/cds-indexer in the CDS extraction pipeline. The indexer is run automatically for projects that declare @sap/cds-indexer as a dependency or devDependency, with graceful error handling that allows compilation to proceed even if indexing fails.

Changes:

• New indexer module (src/cds/indexer.ts) that detects and runs @sap/cds-indexer via npx before CDS compilation
• Integration of indexer orchestration into the main extraction pipeline between dependency installation and compilation phases
• Cache installer enhancements to include @sap/cds-indexer in dependency hash calculation and installation
• Jest configuration update to suppress Node.js v25+ localStorage warnings during test execution
• Dependency updates for TypeScript ESLint tooling (8.55.0 → 8.56.0) and eslint-plugin-jest (29.14.0 → 29.15.0)
