v0.6.0

Restrict search results coming back for LLM from the lunr.js search function. Lunr always returns ALL the search results, so we need to filter these to provide only relevant results (low-ranking results will always be removed). Limited to 10 results (based on relevancy threshold from top result).

Minor bug fixes: Always force markdown conversion on web cache miss and sanitising parameter input from LLM.

Features Included:

• #23 - Ensure Markdown re-created on web cache-miss
• #24 - Ensure input to the searchDoc tool is sanitised for additional resilience
• #25 - limit search results from lunr.js
