Add comprehensive retry logic for A2A agent connections to support eventual consistency in cloud-native deployments.

Features implemented:

  • Configurable retry parameters (MaxRetries, RetryInterval, InitialBackoff)
  • Exponential backoff retry during agent initialization
  • Background reconnection for failed agents
  • Graceful degradation when agents are unavailable
  • Dynamic middleware that adapts to agent availability

Resolves #139

Add comprehensive retry logic for A2A agent connections to support
eventual consistency in cloud-native deployments.

Features implemented:
- Configurable retry parameters (MaxRetries, RetryInterval, InitialBackoff)
- Exponential backoff retry during agent initialization
- Background reconnection for failed agents
- Graceful degradation when agents are unavailable
- Dynamic middleware that adapts to agent availability

Configuration options:
- A2A_MAX_RETRIES (default: 3) - Maximum retry attempts
- A2A_RETRY_INTERVAL (default: 5s) - Maximum delay between retries
- A2A_INITIAL_BACKOFF (default: 1s) - Initial backoff duration
- A2A_ENABLE_RECONNECT (default: true) - Enable background reconnection
- A2A_RECONNECT_INTERVAL (default: 30s) - Background reconnection interval

This enables deployment order independence - the inference gateway
can now be deployed before agents and will automatically connect
once agents become available.

Resolves #139

  • Read changed files to understand current state
  • Remove inline comments from the code
  • Fix any CI issues (linting, formatting, build)
  • Test and commit changes

What was fixed:

🔧 CI Issue Fixed:

  • Type error in a2a/client.go:228: Fixed bit shift operation with float64 by converting to uint(1)<<uint(attempt-1) to ensure integer operands

🧹 Inline Comments Removed:

  • a2a/client.go: Removed error variable comments, agent status comments, retry logic comments, and background reconnection comments
  • api/middlewares/a2a.go: Removed bypass header comments and context key comments
  • config/config.go: Removed connection retry configuration section comment

Changes committed:

All fixes have been pushed to the claude/issue-139-20250719-1049 branch in commit 8280899.
