Added @modelcontextprotocol/inspector as dev dependency
Updated inspect script to use mcp-inspector instead of generic inspector
Added DANGEROUSLY_OMIT_AUTH flag for local development
Added documentation for debugger control flow tools
Added documentation for Runtime object inspection tools
Reorganized tool listings into logical groups
Added Runtime.getProperties for inspecting object properties
Added Runtime.callFunctionOn for executing functions on objects
Added Runtime.awaitPromise for handling async debugging
Consolidated memory profiling functionality into main MCP server
Removed memory-mcp.ts, memory-index.ts, and memory-profiler.ts
Updated package.json to remove build:memory script
- Change heapSnapshotsMap to use JSC.Heap.SnapshotResponse type
- Fix TrackingStartEvent and TrackingCompleteEvent handlers
- Use correct property names (timestamp, snapshotData)
Add comprehensive memory profiling capabilities through Heap domain:
- Heap.enable/disable for enabling heap profiling events
- Heap.snapshot for taking heap memory snapshots
- Heap.gc for triggering garbage collection
- Heap.startTracking/stopTracking for tracking heap changes
- Heap.getPreview/getRemoteObject for inspecting heap objects

- ScriptProfiler.startTracking/stopTracking with optional sampling
- getCPUProfiles helper for retrieving collected profiles
Update state management to track:
- Heap snapshots per URL
- Garbage collection events per URL
- CPU profiling data per URL
Also add index.js to .gitignore as it is a build artifact
