hermes - 💡(How to fix) Fix [Bug]: Email gateway: Lack of subject-based session isolation and excessive notification volume [1 pull requests]

Bug Description

The email gateway currently fails to isolate sessions based on the email subject line. When a user sends a message with a new subject while a task is already running, Hermes interrupts the current task instead of treating the new subject as a separate, isolated session. This behavior makes the email gateway difficult to use for concurrent or context-switching tasks.

Additionally, the gateway produces an overwhelming amount of notification noise. For a single user request, Hermes may send 100–200 emails containing redundant status updates such as "still working..." or "looking...".

Steps to Reproduce

1. Configure and start the Hermes agent with the email gateway enabled.
2. Send an email to the agent with Subject A containing a long-running task (e.g., "Research and summarize the history of LLMs").
3. While the agent is processing, send a second email with Subject B containing a different query.
4. Observe that the agent interrupts the task from Subject A to handle Subject B.
5. Monitor the inbox during the process to observe the high volume of status update emails.

Expected Behavior

1. Session Isolation: Each unique email subject should be treated as an isolated session. A message with a new subject should not interrupt a task running under a different subject.
2. Notification Throttling: Status updates (e.g., "still working") should be batched, throttled, or sent only upon significant milestones to prevent inbox flooding.

Actual Behavior

1. Task Interruption: Any incoming email from the same sender appears to hijack the current active session regardless of the subject line.
2. Email Spam: The user receives 100–200 redundant emails for a single interaction, making the gateway nearly unusable due to the volume of "useless" info.
