fix(tools): browser handler safety + fuzzy_match docstring accuracy

1. browser_tool.py: Replace **args spread on browser_click, browser_type,
   and browser_scroll handlers with explicit parameter extraction. The
   **args pattern passed all dict keys as keyword arguments, causing
   TypeError if the LLM sent unexpected parameters. Now extracts only
   the expected params (ref, text, direction) with safe defaults.

2. fuzzy_match.py: Update module docstring to match actual strategy
   order in code. Block anchor was listed as #3 but is actually #7.
   Multi-occurrence is not a separate strategy but a flag. Updated
   count from 9 to 8.
