💡 What: Replaced the regex-based htmlToText parser with a zero-allocation, byte-level parsing loop.
🎯 Why: Regular expressions create significant execution overhead and memory allocations when parsing large HTML payloads in the web fetch tool. This approach forces multiple passes and intermediate allocations.
📊 Impact: Eliminates regex engine overhead and significantly reduces memory allocations during string parsing.
🔬 Measurement: Compare test benchmark profiles for htmlToText before and after the change using standard Go benchmarking.

Replaced the regex-based `htmlToText` parser with a zero-allocation, byte-level parsing loop in `internal/tools/web.go`. Regular expressions create significant execution overhead and memory allocations when parsing large HTML payloads in the web fetch tool. This manual string builder approach completely bypasses the regex engine overhead.
