v0.1.0 - Bug fixes and stability improvements

What's Changed

Bug Fixes

• Fix tool arg validation: Negative/NaN max_steps and timeout_seconds now fall back to defaults instead of causing silent failures
• Fix error signaling: Add is_error flag to tool results when handlers return success:false, so Claude knows actions failed
• Fix timeout step counting: Use meaningfulSteps consistently across all exit paths (was using steps.length for timeouts)

Improvements

• Add sliding window for messages: Trim to last 20 exchanges to prevent context bloat from accumulated screenshots (~170k+ tokens possible without trimming)

Documentation

• Document security considerations: API key sharing, CORS policy, and context management limits
