Removed #include logging.hpp from 12 headers that had zero logging
symbol usage. Added explicit #include <fmt/format.h> to 3 headers that
have fmt::formatter specializations (grpc_utils.hpp, modelversionstatus.hpp,
nodeinfo.hpp). Added explicit #include logging.hpp to 2 files that lost
transitive include (tensor_conversion.hpp, tensor_conversion_common.cpp).
Updated BUILD deps: replaced libovmslogging with @fmtlib where only
fmt was needed.

…odel.hpp

- Removed #include <openvino/openvino.hpp>, replaced with forward
  declaration of ov::Core (only used as unique_ptr member)
- Removed #include <spdlog/spdlog.h> (unused in header)
- Removed #include <sys/stat.h> (unused in header)
- Replaced #include model.hpp with modelconfig.hpp + forward decl of
  Model. Moved modelFactory() body to modelmanager.cpp.
- Added #include <openvino/openvino.hpp> to modelmanager.cpp
- Added #include model.hpp to 4 .cpp files and 4 test files that
  used Model via shared_ptr through the transitive include.

This eliminates the entire OpenVINO umbrella header and spdlog from
the 17 translation units that include modelmanager.hpp.

…name

- Removed #include <fstream> (unused in header, added to .cpp)
- Removed #include <set> and dead static member configAllowedLayouts
  (declared but never defined or used anywhere)
- Removed #include anonymous_input_name.hpp, moved isShapeAuto(),
  isShapeAnonymous(), isShapeAnonymousFixed(), anyShapeSetToAuto()
  bodies from inline in header to modelconfig.cpp
- Added #include <fstream> and anonymous_input_name.hpp to .cpp

…to decouple mediapipe from ModelManager

- Create ServableNameChecker interface (servableExists) and MetricProvider
  interface (getMetricRegistry, getMetricConfig)
- ModelManager inherits both interfaces
- MediapipeFactory uses unique_ptr, forward-declared in modelmanager.hpp
- mediapipegraphdefinition.hpp/cpp depend on ServableNameChecker, not ModelManager
- mediapipefactory.hpp/cpp depend on interfaces, not ModelManager
- Remove dead parameters: retire(), create(), retireOtherThan(), revalidatePipelines()
- Add explicit mediapipefactory.hpp includes where needed (4 src + 3 test files)

…hecking

- Add ServableType enum (Model, Pipeline, Mediapipe) with bitmask operators
- servableExists() accepts ServableType check param to specify which types to check
- Mediapipe validate: checks Model | Pipeline (skips self)
- DAG validate: checks Model | Mediapipe (skips self), removes mediapipefactory.hpp include
- Model loading: checks Pipeline | Mediapipe (skips self), removes #if MEDIAPIPE_DISABLE guards
- All three servable types now use the same unified servableExists() function

…apper

- Change PipelineFactory member from value to unique_ptr in ModelManager
- Forward-declare PipelineFactory, Pipeline, ModelInstance, ModelInstanceUnloadGuard in modelmanager.hpp
- Move pipeline_factory.hpp include from modelmanager.hpp to modelmanager.cpp
- Remove template createPipeline wrapper from ModelManager
- Callers now use getPipelineFactory().create() directly
- Add explicit pipeline_factory.hpp includes to files that need it

…ableType::Pipeline

- Add ServableDefinition pure virtual interface (getName, isAvailable)
- Add SingleVersionServableDefinition bridging ServableDefinition + Servable
- Model implements ServableDefinition directly
- PipelineDefinition inherits SingleVersionServableDefinition (removes pipelineName member)
- MediapipeGraphDefinition inherits SingleVersionServableDefinition (removes name member)
- Add Bazel targets for new headers

…cades

- Add ModelManager::findServableDefinition() centralizing model->pipeline->mediapipe lookup
- Refactor KFS getModelReady to use findServableDefinition (removes nested #if blocks)
- Refactor KFS ModelMetadataImpl to use findServableDefinition
- Refactor model_service getModelStatus to use findServableDefinition
- Refactor CAPI OVMS_GetServableState to use findServableDefinition
- Remove unused duplicate BUILD targets: libovmshttpservermodule, libovms_dags_pipelinedefinition
- Fix copyright year in single_version_servable_definition.hpp

- Expand SingleVersionServableDefinition with virtual methods:
  getStatus(), getInputsInfo(), getOutputsInfo(), getMetricReporter(),
  notLoadedYetCode(), notLoadedAnymoreCode()
- Unified waitForLoaded() in SingleVersionServableDefinition base class
- Add StatusMetricReporter abstract base to model_metric_reporter.hpp
- Unify ServableDefinitionUnloadGuard (replaces PipelineDefinitionUnloadGuard
  + MediapipeGraphDefinitionUnloadGuard)
- Remove mediapipe includes from model_service.cpp and capi.cpp
- Unify KFS buildResponse for pipeline/mediapipe paths
- Add getServableDefinitionNames() to ModelManager
- Add tensorinfo_fwd.hpp for forward declarations
- Fix dangling reference: use getName() instead of constructor parameter
  in PipelineDefinition and MediapipeGraphDefinition constructors

…forward-declare servable types in mediapipegraphdefinition.hpp, remove iostream

…w OpenVINO include in kfs_grpc_inference_service.hpp, move mediapipe parse_text_proto/status to cpp

…e KFS deps from core

Phase 3E: Split libovms_mediapipe from ovms_lib into separate target
Phase 3F: Extract NodeInitializer registry pattern from initializeNodes()
  - Created node_initializer.hpp/.cpp with NodeInitializer interface + registry
  - Created graph_side_packets.hpp extracted from mediapipegraphdefinition.hpp
  - 7 self-registering concrete initializers in their calculator directories
  - Refactored ~250 line God function to ~15 line registry loop
Phase 3G: Split frontend executors from core mediapipe
  - libovms_mediapipe (core: factory, definition, executor, config)
  - libovms_mediapipe_kfs_executor (kfs_graph_executor_impl)
  - libovms_mediapipe_http_executor (http_graph_executor_impl)
Phase 3H: Remove dead KFS/TFS deps from core mediapipe
  - Removed 5 dead includes (zero symbols used)
  - Replaced //:ovms_dependencies with specific rapidjson + mediapipe deps
  - Calculator deps stay at ovms_lib level (not in libovms_mediapipe)
  - Node initializers use logging.hpp instead of direct spdlog
  - Fixed missing rapidjson/document.h in rerank_servable.hpp
