refactor: use the built-in max/min to simplify the code

[nuxtreact]

In Go 1.21, the standard library includes built-in max/min function, which can greatly simplify the code.

Greptile Overview

Greptile Summary

Replaced manual min calculation pattern (if end > len(indices) { end = len(indices) }) with Go's built-in min() function in two batching loops within ensureProposerEpoch and ensureSyncPeriod methods.

• Simplified code by using min(i+batch, len(indices)) instead of the three-line conditional pattern
• Leverages Go 1.21+ built-in function for cleaner, more idiomatic code
• No functional changes, purely a refactoring for readability

Confidence Score: 5/5

• This PR is safe to merge with no risk
• Simple refactoring that replaces a well-tested pattern with equivalent built-in functionality. The logic is mathematically identical, and Go 1.24.6 is in use (well above the required Go 1.21). No behavioral changes or edge cases introduced.
• No files require special attention
