Issue Type:
Task / Technical Debt

Priority:
Medium

Description:
Objective: Update the browser_use library from version 0.7.10 to the latest stable release and implement necessary code changes to maintain compatibility.

Current State:

Current version: browser_use==0.7.10 (defined in src/backend/requirements.txt)
Used in: Browser automation service for vision AI element identification
Key integration points:
tools/browser_use_service.py - Main service entry point
tools/browser_use_tool.py - CrewAI tool interface
browser-service/browser_service/tasks/workflow.py - Agent implementation
Multiple API endpoints and metrics tracking
Scope of Work:

Version Analysis

Review browser_use changelog/release notes from v0.7.10 to latest
Identify breaking changes, deprecated APIs, and new features
Document migration requirements
Code Impact Assessment

Audit all browser_use imports and API usage across codebase
Check Agent class initialization and method signatures
Verify custom actions compatibility (ENABLE_CUSTOM_ACTIONS)
Review locator extraction and validation logic
Implementation

Update src/backend/requirements.txt with new version
Refactor affected code in:
browser_service/tasks/workflow.py (Agent usage)
browser_service/agent/ (custom actions)
tools/browser_use_tool.py (API client)
Update configuration if new options available
Ensure Windows UTF-8 compatibility maintained
Testing & Validation

Test workflow endpoint (POST /workflow)
Verify batch processing functionality
Validate locator generation (ID, CSS, XPath, Playwright selectors)
Test with both Browser Library and SeleniumLibrary modes
Confirm metrics tracking still works
Documentation:

Update CHANGELOG.md with upgrade details
Document any new configuration options
Update inline comments if API usage changed
Affected Components:

Browser automation service (Flask API)
Task processor and workflow execution
Agent management and custom actions
Locator generation and validation
Metrics tracking system
Dependencies:

Requires playwright compatibility check
May affect robotframework-browser[bb] integration
Verify langchain-google-genai compatibility
Acceptance Criteria:

[ ] browser_use upgraded to latest stable version
[ ] All existing functionality works without regression
[ ] Tests pass for both Browser and Selenium library modes
[ ] No breaking changes in API endpoints
[ ] Documentation updated
[ ] CHANGELOG.md reflects the upgrade
Risk Assessment:

Medium risk: Core dependency for vision-based automation
Mitigation: Test in isolated environment first, maintain rollback capability
