[log] Add debug logging to 5 workflow pkg files

[github-actions]

Adds meaningful debug log calls to code paths that previously had no visibility under DEBUG=workflow:*.

Changes

pkg/workflow/runtime_overrides.go

• Log when a runtime ID is not in existing requirements (entering the else branch)
• Log when cloning a known runtime with custom action config vs. using it as-is
• Log when creating a new RuntimeRequirement from a known runtime
• Log when skipping an unknown runtime with no action-repo specified

pkg/workflow/engine_api_targets.go

• GetCopilotAPITarget: entry log + log which resolution path is taken (explicit api-target vs. derived from GITHUB_COPILOT_BASE_URL)
• GetGeminiAPITarget: entry log + log which path is taken (custom GEMINI_API_BASE_URL, default endpoint, or empty)

pkg/workflow/slash_command_parser.go

• expandSlashCommandShorthand: log the expansion (/command → slash_command + workflow_dispatch)

pkg/workflow/label_trigger_parser.go

• parseLabelTriggerShorthand: log when input does not match any label trigger pattern
• getItemTypeName: log the resolved human-readable type name

pkg/workflow/service_ports.go

• parsePortSpec: log entry with spec value and type
• Log when integer port specs are parsed successfully
• Log when UDP or unsupported-protocol ports are skipped
• Log when a port range is expanded (count and bounds)

Testing

All changes follow the established logger patterns for each file. The make build target fails in this environment due to a pre-existing Go toolchain version mismatch (go.mod requires 1.25.8, environment has 1.24.13 with GOTOOLCHAIN=local). The changes are syntactically valid additions of log.Print/log.Printf calls using pre-existing logger variables.
