MD5 is cryptographically broken and prone to collision attacks. While used here for caching, it is best practice to use stronger algorithms like SHA-256. Changes: - Replaced 'md5' with 'sha256' in OpenRouterClient.hashText method. - Verified that the new logic produces 64-character SHA-256 hashes. - In-memory cache will be automatically invalidated on the next run, which is acceptable for this use case.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

- Replaced weak MD5 hashing with SHA-256 for text caching in OpenRouterClient. - Moved windows-specific sqlite-vec dependency to optionalDependencies to fix CI failure on Linux runners. The hashing change improves collision resistance for the embedding cache. The dependency change resolves 'EBADPLATFORM' errors during 'npm ci' on Linux.

- Replaced weak MD5 hashing with SHA-256 for text caching in OpenRouterClient. - Fixed CI failure by moving windows-specific sqlite-vec to optionalDependencies. - Resolved 18 ESLint errors across multiple files to fix the Lint check. - Used hex codes in regex to satisfy no-useless-escape without changing logic. The security fix improves collision resistance for the embedding cache. The CI fixes ensure the project can be built and tested on Linux runners with strict linting.

@jules i see 4 conflicts for these : |
I have addressed the linting errors in these files in my latest submission. I don't see any merge conflict markers locally. If there are conflicts with the base branch, they might need to be resolved via a rebase or merge from your side, as I don't have direct tools to pull and rebase against the target branch. However, I have verified that all linting issues (prefer-const, no-useless-escape, require-to-import, etc.) have been fixed in the current version of the PR. |

🎯 What: The vulnerability fixed is the use of the weak MD5 hashing algorithm for text hashing in the embedding cache.
⚠️ Risk: MD5 is cryptographically broken. Using it for cache keys could potentially lead to hash collisions, although the risk is low in this specific context (in-memory caching of embeddings).
🛡️ Solution: Switched the hashing algorithm to SHA-256, which is more secure and has better collision resistance. This results in 64-character hex strings instead of 32-character ones.
