feat(go): introduce context.Context to client methods

[chengxilo]

Which issue does this PR close?

N/A

Rationale

Standardizing the Go SDK to support context.Context across all client methods. This allows users to handle timeouts, cancellations

What changed?

The iggcon.Client interface and its TCP implementation have been updated to include context.Context as the first parameter for all API methods.
Correspondingly, all internal command-handling logic now respects context deadlines and cancellations.

Local Execution

• Passed
• Pre-commit hooks ran

AI Usage

1. Claude Sonnet 4.6
2. Add context parameters, initial implementation of test (modifed manually)
3. I read the code and test
4. yes
