v0.5.0

Added

• GitHub repository clone extraction for fetch_content -- detects GitHub code URLs, clones repos to /tmp/pi-github-repos/, and returns actual file contents plus local path for further exploration with read and bash
• Lightweight API fallback for oversized repos (>350MB) and commit SHA URLs via gh api
• Clone cache with concurrent request deduplication (second request awaits first's clone)
• forceClone parameter on fetch_content to override the size threshold
• Configurable via ~/.pi/web-search.json under githubClone key (enabled, maxRepoSizeMB, cloneTimeoutSeconds, clonePath)
• Falls back to git clone when gh CLI is unavailable (public repos only)
• README: GitHub clone documentation with config, flow diagram, and limitations

Changed

• Refactored extractContent/fetchAllContent signatures from positional timeoutMs to ExtractOptions object
• Blob/tree fetch titles now include file path (e.g. owner/repo - src/index.ts) for better disambiguation in multi-URL results and TUI

Fixed

• README: Activity monitor keybinding corrected from Ctrl+Shift+O to Ctrl+Shift+W
