feature: task icon change to blue chat bubble when waiting for reply

[zfoong]

What and Why

Users sometimes are not aware of when a task is pending for their attention or reply. So having some indication will be great. Also, the status bar used to update its status, but at some point stopped working.

Items changes/features added

• Shorten the task session ID UUID to reduce LLM's effect and reduce hallucination
• Task icon now changes to a blue message bubble when the agent is waiting for reply.
• Status bar changes to "waiting for your response..." when the agent is waiting for the user's reply

Test

Checklist

• Agent create task and send user message with parameter wait_for_user_reply set to true. Then the status bar appears to be "waiting for your response...". Once the user replies, the status bar becomes "Working on...".
• Task icon turns into a blue chat bubble when the agent is waiting for the user's response, and once the user replies, the icon returns to the 'running' icon.
• Test on mutli-tasking too.
• Think of more edge cases.

Objectives:

• Test out user experience when agent is waiting for user response
• Test out multitasking function
• Create edge case ideas

PR Review Results:

• Task displays status correctly (blue icon when waiting for response)
• Agent was able to handle multitasking without conflicts or error

Edge Cases Proposal:

• Multitasking: Ask agent to handle multiple complex tasks (e.g. heavy research, multistep tasks) while conversing with agent for testing task handling and performance
• Conflicting parallel tasks: Create two exact same tasks and both task to wait for response at the same time to test parallel task handling

Suggestions:

• Status bar to show task statuses individually, if it waits during conversation sometimes user might not know
