…n, fix docs and includes

- Add --source_loras CLI parameter for specifying LoRA adapters
  Format: alias=org/repo@file.safetensors (comma-separated, @file optional)
- Add LoRA adapter entries to image_gen_calculator.proto
- Parse and validate LoRA settings in image_generation_graph_cli_parser
- Export LoRA adapter entries in graph.pbtxt generation
- Load LoRA .safetensors via ov::genai::Adapter in pipelines.cpp
- Apply LoRA adapters at inference time based on model name routing
- Download LoRA repos via curl (resolve safetensors filename from HF API)
- Add LoRA alias routing in mediapipe factory
- Pass modelName through HttpPayload for LoRA alias matching
- Add 18 unit tests (CLI parsing, graph export, proto parsing, config)

- Support multiple LoRA source types: HF repo, direct URL, local file (alias= required)
- Extract shared curl_downloader utility from gguf_downloader
- Add composite LoRA aliases (e.g. blend=@pokemon:0.7+@Anime:0.5)
- Support per-request lora_weights override in extra_body
- Local files referenced by absolute path in graph.pbtxt (no copy)
- HF LoRA: resolve .safetensors via API, download with curl
- clone() delegates to pullLoraAdapters() for all LoRA downloads
- resolveHfLoraFilenames() + pullLoraAdapters() split (private -> protected)
- Remove loraQueue: T2I/I2I always use clone(), only inpainting serialized
- PipelineSlotGuard (renamed from InpaintingQueueGuard)
- compileProperties built once in constructor (no default arg on reshapeAndCompile)
- CompositeLoraMap type alias replaces duplicate runtime structs
- Multiline composite formatting in graph.pbtxt
- Add RUN_UNSTABLE-gated pull tests for LoRA (HF resolve, download, full-flow)
- Add non-network unit tests (local file skip, non-imagegen no-op)
- Add SetUpServerForDownloadWithLoras test helper
- 59 tests pass (55 original + 4 new, 3 network-gated skip without RUN_UNSTABLE)

Resolved conflicts in:
- pipelines.hpp: keep PipelineSlotGuard name and LoRA fields, adopt main's blocking comment
- pipelines.cpp: keep LoRA adapter loading, compileProperties, adopt main's SPDLOG_ERROR
- http_image_gen_calculator.cc: keep LoRA logic, adopt main's const ref for inpainting tensors
- README.md: accept main's updated examples (model names, sizes, notes)

- Fix downloadFileWithCurl: use overload instead of const ref default parameter
  (was binding temporary to const std::string&)
- Add HF_TOKEN auth header to curl downloads for HF repos only
  (avoid leaking credentials to arbitrary DIRECT_URL servers)
- Rename authToken -> authTokenHF for clarity
- Skip RUN_UNSTABLE tests when HF_TOKEN is not set
- Provide explicit safetensors filename in download tests
- Restore missing 'curl -O' PNG download commands in image_generation README
- Update copilot-instructions rule 13: expanded dangling reference guidance
- Add missing #include <vector>, <utility> (cpplint)
- Fix comment spacing (cpplint)
- clang-format all changed files

MSVC /W4 treats variable shadowing as error (C4456).
Inner loop variable 'it' shadowed outer pipelinesMap iterator.

- Detect Windows absolute paths (e.g. C:\path\to\file.safetensors)
  in addition to Unix paths (/ and ./ prefixes)
- Also detect .\ prefix for relative Windows paths
- Use find_last_of("/\\") instead of rfind('/') to extract
  filename from both Unix and Windows paths
