Fixes #112

This PR resolves the critical bug where CancelTask API endpoint only updated task state in the database but did not actually stop the running task execution.

Problem

Tasks continued to run in the background until completion, even though the task state showed "cancelled". This led to:

  • Wasted compute resources on long-running tasks
  • Inability to stop runaway or incorrect tasks
  • Misleading task states

Solution

  • Added runningTasks map[string]context.CancelFunc to track active tasks
  • CancelTask() now calls actual context cancel functions to stop execution
  • Updated both background and streaming task handlers to use cancellable contexts
  • Added proper cleanup when tasks complete, fail, or are cancelled
  • Added comprehensive tests to verify cancellation works correctly

Testing

  • All existing tests pass
  • New cancellation-specific tests verify the fix works
  • Linting and code quality checks pass

Fix(task): CancelTask now actually stops running task execution
3149508 
Resolves issue #112 where CancelTask only updated database state but didn't stop 
the actual running task execution.

Key Changes:
- Added runningTasks map to DefaultTaskManager to track cancel functions
- CancelTask() now calls actual context cancel functions to stop execution
- Updated both background and streaming task handlers to use cancellable contexts
- Added proper cleanup when tasks complete, fail, or are cancelled
- Added comprehensive tests to verify cancellation works correctly

This ensures that when a client calls tasks/cancel, the task execution actually 
stops immediately instead of continuing to run in the background.

CI Investigation & Fix Tasks

  • Check CI status and identify failing jobs
  • Download and analyze failing job logs
  • Run local linting and tests to identify issues
  • Fix any code issues found
  • Verify fixes work locally
  • Push fixes to PR branch
  • Confirm CI passes

Issues Fixed ✅

The CI failures were caused by formatting issues in the code that were caught by the "Check dirty" step:

  1. server/task_cancellation_test.go - Missing newline at end of file
  2. server/task_manager.go - Trailing whitespace on lines 278 and 317

Both issues have been fixed and committed. The local linting (task lint) and testing (task test) now pass successfully.

Summary

All formatting issues that caused the CI failure have been resolved. The next CI run should pass successfully.
