Submit new upstream PR to gonka-ai/gonka: circuit breaker + probe re-exclusion fix

[mingles-agent]

Goal

Submit a new PR to upstream gonka-ai/gonka replacing the closed PR gonka-ai#974, addressing both reasons x0152 closed it.

What to include

All commits from our development branch that are ahead of upstream/main, specifically:

1. Circuit breaker + reputation-adjusted selection (originally from PR feat: intra-epoch circuit breaker with reputation-adjusted executor selection gonka-ai/gonka#974):

   • inference-chain/x/inference/keeper/circuit_breaker.go — CB state machine, UpdateCBStateForBlock, GetRandomExecutor
   • inference-chain/x/inference/types/ — CBEntry, ValidationParams with CB params
   • Related tests

2. Same-block probe re-exclusion fix (merged in PR fix: prevent same-block re-exclusion after probe success #26, our issue Fix merge conflicts in PR #26 (probe re-exclusion fix) and merge #28):

   • LastRestoredBlock field in CBEntry
   • Grace period check in UpdateCBStateForBlock Pass 2
   • Tests: TestProbeSuccessNotReExcludedSameBlock, TestProbeSuccessCanBeExcludedNextBlock, TestProbeFailureReExcludesImmediately

PR description to use

Title: feat: intra-epoch circuit breaker with reputation-adjusted executor selection

Body should:

• Reference upstream issue Nodes with high miss rate continue receiving inference requests for the rest of the epoch gonka-ai/gonka#975 (Closes Nodes with high miss rate continue receiving inference requests for the rest of the epoch gonka-ai/gonka#975)
• Explain the CB state machine clearly
• Note the probe re-exclusion fix is included
• Keep it focused — no mention of StartInference bypass (out of scope)
