- Added async background job execution for bash and task tools with configurable concurrency limits and automatic result delivery. - Added cancel_job tool and /jobs slash command to manage and inspect running background jobs with status display. - Added jobs:// internal protocol handler for querying job status and retrieving job execution details. - Added async.enabled and async.maxJobs settings to control background job execution behavior. - Enhanced status line to display count of running background jobs with visual indicator. - Implemented AsyncJobManager with exponential backoff retry delivery, job lifecycle tracking, and automatic eviction. Fixes #56.
