[Sync] Update project files from source repository (eec0e19)

[mrz1836]

What Changed

• Updated .dockerignore to exclude dist/ directory but preserve dist/linux/ with !dist/linux/
• Upgraded actions/setup-go from v6.3.0 (commit 4b73464) to v6.4.0 (commit 4a3601121d) in setup-go-with-cache action
• Added clarifying comments to Go module and build cache sections noting "Uses actions/cache which handles both restore and save"
• Updated GO_PRE_COMMIT_VERSION from v1.8.0 to v1.8.1 in pre-commit environment configuration
• Updated GO_PRE_COMMIT_GOLANGCI_LINT_VERSION from v2.11.3 to v2.11.4 in pre-commit environment configuration

Why It Was Necessary

• The dist/linux/ directory needs to be included in Docker builds while other dist artifacts should remain ignored
• Upgrading to newer versions of GitHub Actions and pre-commit tools ensures access to latest bug fixes and improvements
• Additional comments improve maintainability by clarifying cache handling behavior for future developers

Testing Performed

• Verify Docker builds correctly include dist/linux/ artifacts while excluding other dist files
• Confirm GitHub Actions workflows execute successfully with updated actions/setup-go@v6.4.0
• Validate pre-commit hooks function properly with updated tool versions

Impact / Risk

• Risk Level: Low - changes are primarily version bumps and documentation improvements
• Breaking Changes: None - Docker ignore pattern change preserves required Linux artifacts
• CI/CD Impact: Minimal - updated Actions and tooling versions are backward compatible
