Ryan Malloy a41a73af2a style: fix linting errors and update README with new tools

- Auto-fix trailing spaces, curly braces, and indentation issues
- Clean up boolean comparisons and code formatting
- README automatically updated with new code injection tools:
  - browser_enable_debug_toolbar: Enable debug toolbar for client identification
  - browser_inject_custom_code: Inject custom JavaScript/CSS code
  - browser_list_injections: List all active code injections
  - browser_disable_debug_toolbar: Disable debug toolbar
  - browser_clear_injections: Remove custom code injections

All linting checks now pass successfully.

MCP Roots Test Results

✅ Successfully Tested Features

1. Tool Educational Content

All playwright tools now include educational content about MCP roots:

browser_navigate:

ENVIRONMENT: Browser behavior adapts to exposed MCP roots:
- file:///tmp/.X11-unix → GUI browser on available displays (X0=:0, X1=:1)
- file:///dev/dri → Hardware acceleration enabled if GPU available
- file:///path/to/project → Screenshots/videos saved to project directory

TIP: Expose system roots to control browser environment. Change roots to switch workspace/display context dynamically.

browser_take_screenshot:

ENVIRONMENT: Screenshot behavior adapts to exposed MCP roots:
- file:///path/to/project → Screenshots saved to project directory
- file:///tmp/.X11-unix → GUI display capture from specified display (X0=:0)
- No project root → Screenshots saved to default output directory

TIP: Expose your project directory via roots to control where screenshots are saved. Each client gets isolated storage.

browser_start_recording:

ENVIRONMENT: Video output location determined by exposed MCP roots:
- file:///path/to/project → Videos saved to project/playwright-videos/
- file:///tmp/.X11-unix → GUI recording on specified display
- No project root → Videos saved to default output directory

TIP: Expose your project directory via roots to control where videos are saved. Different roots = different output locations.

2. Core Functionality

✅ Browser navigation works: Successfully navigated to https://example.com
✅ Screenshot capture works: Screenshot saved to /tmp/playwright-mcp-output/
✅ Video recording works: Video saved to /tmp/playwright-mcp-output/videos/
✅ MCP server is running and responding on http://localhost:8931/mcp

3. Infrastructure Ready

✅ MCP roots capability declared in server
✅ Environment introspection module created
✅ Browser context integration implemented
✅ Session isolation working

🚧 Next Steps for Full Implementation

Current Status

The educational system is complete and the infrastructure is in place, but the client-side roots exposure needs to be implemented for full workspace detection.

What's Working

Tool descriptions educate clients about what roots to expose
Environment introspection system ready to detect exposed files
Browser contexts will adapt when roots are properly exposed

What Needs Client Implementation

MCP clients need to expose project directories via file:///path/to/project
MCP clients need to expose system files like file:///tmp/.X11-unix
Full dynamic roots updates during session

Expected Behavior (When Complete)

When an MCP client exposes:

file:///home/user/my-project     → Screenshots/videos save here
file:///tmp/.X11-unix           → GUI browser on available displays
file:///dev/dri                 → GPU acceleration enabled

The Playwright tools will automatically:

Save all outputs to the project directory
Use GUI mode if displays are available
Enable hardware acceleration if GPU is available
Provide session isolation between different clients

Summary

The MCP roots system is architecturally complete and ready for client implementation. The server-side infrastructure is working, tools are educational, and the system will automatically adapt to workspace context once MCP clients begin exposing their environment via roots.
