feat: add snapshot size limits and optional snapshots to fix token overflow
Implements comprehensive solution for browser_click and other interactive tools returning massive responses (37K+ tokens) due to full page snapshots. Features implemented: 1. **Snapshot size limits** (--max-snapshot-tokens, default 10k) - Automatically truncates large snapshots with helpful messages - Preserves essential info (URL, title, errors) when truncating - Shows exact token counts and configuration suggestions 2. **Optional snapshots** (--no-snapshots) - Disables automatic snapshots after interactive operations - browser_snapshot tool always works for explicit snapshots - Maintains backward compatibility (snapshots enabled by default) 3. **Differential snapshots** (--differential-snapshots) - Shows only changes since last snapshot instead of full page - Tracks URL, title, DOM structure, and console activity - Significantly reduces token usage for incremental operations 4. **Enhanced tool descriptions** - All interactive tools now document snapshot behavior - Clear guidance on when snapshots are included/excluded - Helpful suggestions for users experiencing token limits Configuration options: - CLI: --no-snapshots, --max-snapshot-tokens N, --differential-snapshots - ENV: PLAYWRIGHT_MCP_INCLUDE_SNAPSHOTS, PLAYWRIGHT_MCP_MAX_SNAPSHOT_TOKENS, etc. - Config file: includeSnapshots, maxSnapshotTokens, differentialSnapshots Fixes token overflow errors while providing users full control over snapshot behavior and response sizes.
