Pull Request

Description
This pull request adds local document uploads for lightweight RAG-style context, web search support for Ollama, and improved Ollama configuration including a timeout setting and Esc-to-cancel behavior. It also refines the popup UI and updates the README with the new workflow and setup instructions.

Related Issue

• Fixes Ajouter un document a l'extension #39
• Fixes Add "Request timeout" configuration option #70

Changes Made

• Added support for uploading local text documents in the popup.
• Stored uploaded documents locally and used them as retrieval context for answers.
• Added a Web search before answering toggle for Ollama.
• Implemented a local proxy search route so web search works without browser CORS issues (may happen only on my machine).
• Added an Ollama timeout setting in the popup.
• Made 0 mean no automatic timeout for Ollama, with Esc held for 2 seconds used to cancel a request.
• Improved popup styling for the new document and web search controls.
• Updated the README with Ollama setup, proxy usage, web search, and document workflow instructions.

Screenshots (if applicable)

• Ollama settings

• Web search and uploaded documents options

Checklist

• I have tested the changes locally.
• I have updated the documentation accordingly.
• All tests pass successfully.

Additional Notes

• The Ollama setup is recommended to use the local proxy at http://127.0.0.1:8787/v1.
• Uploaded documents currently support lightweight text-based files for the first version.
• Web search and document context are both meant to improve answer quality for Ollama-based runs.

Thx you for your participation and hard work :)

Just it would be nice if host could support all port instead of localhost:xxxx/*
