feat: add step.statemachine_transition and step.statemachine_get pipeline steps

[intel352]

Summary

• Adds step.statemachine_transition — triggers a named state machine transition from within a pipeline, with template resolution for entity_id, event, and data fields; configurable fail_on_error (default false)
• Adds step.statemachine_get — reads the current state of a workflow instance, returning current_state and entity_id outputs
• Registers both steps in plugins/statemachine via StepFactories() and declares them in the manifest's StepTypes

Test plan

• TestStateMachineTransitionStep_* (13 cases): factory validation, successful transition, templated entity/event, invalid transition with fail_on_error=false and true, data pass-through, missing service, wrong service type, nil app, mock TransitionTrigger interface
• TestStateMachineGetStep_* (8 cases): factory validation, returns correct state, templated entity_id, state after transition, missing instance, missing service, wrong type, nil app
• TestStepFactories in statemachine plugin: both step types present
• TestPluginManifest: manifest declares 2 step types
• All existing statemachine and module tests continue to pass

go test ./module/... -run TestStateMachine
go test ./plugins/statemachine/...

Pull request overview

Adds new pipeline steps to interact with the state machine engine from within pipelines, and wires them into the statemachine plugin so they’re discoverable/usable via plugin loading. The PR also introduces and registers an additional CI/CD step (step.build_from_config) that is not currently reflected in the PR’s stated scope.

Changes:

• Add step.statemachine_transition and step.statemachine_get pipeline steps (with template resolution) plus unit tests.
• Register the new state machine steps in plugins/statemachine and validate via plugin tests/manifest step type assertions.
• Add/register step.build_from_config in the CI/CD plugin and add its module implementation + tests.

• The error from copyDirRecursive(...) is ignored, so this test can silently proceed with an incomplete copy and produce confusing follow-on failures. Please assert copyDirRecursive succeeds (e.g., fail the test immediately on error).

				copyDir := t.TempDir()
				_ = copyDirRecursive(capturedBuildDir, copyDir)
				capturedBuildDir = copyDir
			}

• Test name has a typo (NoPLugins). Renaming to NoPlugins will keep test naming consistent and easier to search/grep.

• This PR appears to introduce/register step.build_from_config in the CI/CD plugin, but the PR title/description focus on statemachine steps and don’t mention this additional feature. Please update the PR description (and/or split into a separate PR) so reviewers can clearly track the scope and rationale of the CI/CD change.

copyFile() creates files with mode 0600. That means config.yaml in the Docker build context will be root-readable only, and the generated image can fail at runtime when using non-root base images (e.g., distroless:nonroot) because /app/config.yaml won’t be readable. Consider setting a less restrictive mode for the config (e.g., chmod config.yaml after copy, or make copyFile accept a mode) so the runtime user can read it.
