feat(alerting): optimize alerting with dynamic routing and suppressio…

[DebasmitaBose0]

Summary

Integrates a dedicated alert routing engine and a rolling alert suppression filter into the alerting loop to minimize redundant notification noise and send critical alerts to higher-priority channels.

Proposed Changes

• [NEW] router.py : Dynamic alert routing module checking risk levels and assigning targets (Slack vs. PagerDuty).
• [NEW] filters.py : Deduplication filters that identify looping or duplicate agent alerts in the same session.
• [NEW] test_alerting_router.py : Unit tests for path selection and suppression key evaluation.
• [NEW] alert_routing.md : Documentation on setting up filters.
• [MODIFY] engine.py : Hooks up the new router and filters in AlertingEngine's publish pipeline.

Verification Plan

Executed python -m pytest tests/test_alerting_router.py which passes successfully.

Closes #521

Warning

Review limit reached

@DebasmitaBose0, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 45 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
