fix(e2e): run complete CLI package

[ekalinin]

Summary

Run the complete cmd/gh-md-toc package in the Makefile e2e commands instead of compiling only main.go.

Regression source

The regression was introduced in PR #60.

That PR moved CLI configuration and parseConfig from main.go into a separate config.go file. The Makefile continued to execute:

go run cmd/gh-md-toc/main.go

Running a specific Go file compiles only that file, so config.go was excluded and every e2e command failed with:

cmd/gh-md-toc/main.go:27:14: undefined: parseConfig

The issue was discovered while validating PR #64 and is intentionally fixed in this separate PR.

Fix

Update all three e2e command variables to run the complete CLI package:

go run ./cmd/${EXEC}

This includes every Go file in cmd/gh-md-toc, including main.go and config.go.

The change covers:

• local Markdown e2e scenarios
• raw remote Markdown e2e scenarios
• GitHub blob URL e2e scenarios

Verification

make e2e passes all nine scenarios:

• local Markdown with default options
• local Markdown with depth and escaping options
• local Markdown with custom indentation
• raw remote Markdown with default options
• raw remote Markdown with depth and escaping options
• raw remote Markdown with custom indentation
• GitHub blob URL with default options
• GitHub blob URL with depth and escaping options
• GitHub blob URL with custom indentation

All generated results match the existing golden files.
