try to fix deadlock/timeout in logpoller tests

15 successful runs: https://github.com/smartcontractkit/chainlink/actions/runs/25488891367 ✅
Requires: smartcontractkit/chainlink-evm#463 (merged ✅)

Made with AI and explained as:

  That said, the fix is mechanically sufficient: recvReplayComplete now also selects on lp.stopCh, so when Close() runs close(lp.stopCh) and then wg.Wait(), every recvReplayComplete goroutine — whether spawned before or after close(stopCh) — observes the closed channel and exits. The previous "send must arrive before
  goroutine starts receiving" timing dependence is gone.

Hoping to solve deadlocks like this one, which are endemic in chainlink repo:

Pull request overview

Risk Rating: MEDIUM

This PR updates the repository’s github.com/smartcontractkit/chainlink-evm dependency to pick up an upstream fix intended to reduce logpoller-related test deadlocks/timeouts, and regenerates generated artifacts impacted by that bump (notably config docs).

Changes:

• Bump github.com/smartcontractkit/chainlink-evm to v0.3.4-0.20260507171202-46e6a397da2d across root and submodule go.mod files (and corresponding go.sum updates).
• Regenerate docs/CONFIG.md, which (notably) changes Mantle chain default GasEstimator.LimitDefault/LimitMax values.

Scrupulous human review needed:

• Verify the chainlink-evm bump actually contains the intended goroutine shutdown / deadlock fix (since the core logic change is upstream and not visible in this diff).
• Confirm the Mantle Mainnet/Sepolia default gas estimator limit changes in docs/CONFIG.md are intentional and acceptable, and update the PR description accordingly (see comments).
