Refactor Component-Service Layer

Pull request overview

This PR refactors how Aegis Stack tracks component/service file ownership and feature detection by making the spec registry (and each spec’s FileManifest) the single source of truth. It also adds a suite of guard/characterization tests to prevent silent drift in manifests, shared-file regeneration, and CLI option parsing/interactive selection flows.

Changes:

• Derive post_gen_tasks.get_component_file_mapping() from FileManifest via compute_file_mapping(); extend get_component_files() to support a “full footprint” for removals (option-gated extras included).
• Introduce PluginSpec.marker_path and update aegis update feature detection to use registry-driven markers (instead of a hand-maintained path map).
• Add/expand tests that lock in these contracts (derived mappings, marker correctness, shared-file completeness, CLI parsing/interactive selection behavior).

aegis/core/file_manifest.py	Documents and exposes compute_file_mapping() as the source for derived file mappings.
aegis/core/copier_updater.py	Uses AnswerKeys.ANSWERS_FILENAME and derives service name set from the service registry.
aegis/core/copier_manager.py	Uses AnswerKeys.ANSWERS_FILENAME for copier answers handling.
aegis/core/components.py	Adds marker_path to components and models scheduler persistence as a manifest “extras” group.

aegis/cli/callbacks.py	Collapses per-service option parsing blocks into a handler registry while preserving messages/side effects.
tests/core/test_file_mapping_derivation.py	Adds guards that the mapping is derived, manifest paths exist, markers resolve, and footprints split correctly.
tests/core/test_constants_usage.py	Adds a source scan guard to prevent hardcoding shared constants (answers filename, infra order drift).
tests/cli/test_update_feature_detection.py	Adds characterization + registry-driven detection coverage for _detect_existing_features.
tests/cli/test_shared_files_completeness.py	Adds a “minimal vs maximal stack diff” guard ensuring stack-dependent shared files are registered/allowlisted.
