Port llama.cpp's HuggingFace hub-cache subsystem (http.h, hf-cache.{h,cpp})
into whisper.cpp's shared common library and wire -hf/--hf-repo +
-hff/--hf-file into whisper-cli. Phase 1 is cache-only: whisper_hf_resolve_model
scans the on-disk HF hub cache (get_cached_files + finalize_file) and maps
org/repo (+ optional file) to a concrete snapshot path, so a model already
pulled by the hf CLI resolves with no -m path. An explicit -m still wins and
the no-args default stays models/ggml-base.en.bin.
The network download path is compiled but unused this phase (enabled in
Phase 2). Adds tests/test-hf-resolve.sh covering cache hit, missing-file
error (exit 3), -m regression, and the default path.

* common: add memory buffer overload of read_audio_data
whisper-server /inference without --convert passed the uploaded file
bytes to read_audio_data as a filename, so ma_decoder_init_file tried
to open a path starting with "RIFF" and failed. every request returned
HTTP 400 "Invalid request" on builds without WHISPER_FFMPEG, which is
the default.
factor the PCM extraction into a shared helper and add an overload that
decodes straight from a memory buffer via ma_decoder_init_memory, which
the function already used for the stdin path. server now calls it with
the upload content. the filename overload behavior is unchanged.
