Implement R007/R008: Task system for client work distribution

Server-side:
- Created TaskMessage class with parameters support
- Implemented TaskManager service with task lifecycle management
- Added task endpoints: create, pending, claim, complete, status
- Task states: Pending, Claimed, InProgress, Completed, Failed
- 24-hour task retention with automatic cleanup

Client-side:
- Added TaskReceiverOperatingMode for processing tasks
- Supports tag-based task filtering
- Executes configured processor script with task JSON
- Reports results back to server

Bot integration:
- Added task commands: task, tasklist, taskstatus
- Integrated with bot plugin system

Tests:
- Comprehensive unit tests for TaskManager
- All tests passing (53 total)

Usage:
- Client: taskreceiver --tags "build,test" --processor "./run.ps1"
- Bot: /task "Build project" tags:build params:{"url":"..."}
