Alert #muzzlefeedback on OpenAI 429 responses

[Copilot]

OpenAI rate-limit failures were surfacing as ordinary request errors, with no operational signal in Slack. This change notifies #muzzlefeedback whenever an OpenAI call returns 429, using the error message returned by OpenAI.

• Summary

  • Centralized 429 handling for OpenAI-backed flows in the backend AI service.
  • Preserves existing error propagation while adding a Slack alert with the returned OpenAI message.

• Implementation

  • Added a shared alertOnOpenAiRateLimit(error, operation) path in AIService.
  • Detects OpenAI status === 429.
  • Extracts the nested API message when present (error.message fallback otherwise).
  • Sends a compact alert to #muzzlefeedback and avoids altering non-429 behavior.

• Covered call sites

  • Text generation
  • Prompt-with-history
  • Participation replies
  • Corpo-speak generation
  • Moonbeam redeploy quote generation
  • Memory extraction

• Regression coverage

  • Added focused specs for direct 429 alerting behavior.
  • Added flow-level coverage to verify the alert path is invoked from OpenAI failure cases.

await this.alertOnOpenAiRateLimit(error, 'generateText');

// Example Slack message:
// OpenAI 429 during generateText: Please slow down.

Pull request overview

Adds operational visibility for OpenAI rate-limit failures by emitting a Slack alert to #muzzlefeedback whenever an OpenAI-backed flow receives a 429, while preserving existing error propagation/handling semantics.

Changes:

• Introduces AIService.alertOnOpenAiRateLimit(error, operation) plus helpers to extract OpenAI status/message safely.
• Wires the alert into all OpenAI-backed flows called out in the PR (text, corpo-speak, prompt-with-history, participation, Moonbeam redeploy quote, and memory extraction).
• Adds focused unit coverage for the new alert behavior and verifies it’s invoked from failure paths.

Fixed in 095c0c2. I added the missing 429 alert branch coverage and re-ran the backend coverage gate successfully.
