Feat/static discovery v2

[andthattoo]

Pull Request

Summary

Resolves #76

Motivation

Static discovery and cloud/internet setups often report 127.0.0.1 as the local IP, which remote shards cannot use to send tokens back to the API node. This PR adds an explicit callback address override and fixes several minor issues discovered during testing.

Changes

• Add DNET_API_CALLBACK_ADDR environment variable to specify a reachable callback address for remote shards
• Include own device in /devices response for static discovery (which only returns peers)
• Fix Makefile typo: .PHONEY → .PHONY
• Fix Makefile lint-fix target to use $(UV_RUN) consistently
• Improve ensure-env target to check if .env.example exists before copying
• Add mlx, mlx_lm to mypy ignore list and fix exclude paths

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Code refactoring

• CI/CD improvement

• Added new tests for the changes
• Existing tests updated

Looks good! We need multi-device CI/integration test to discover these issues (we can create a GitHub issue for now).
