Define the PdfSource trait abstraction over PDF byte sources. This trait provides a uniform API for reading PDF data from different sources: local files (MmapSource, FileSource), and eventually remote HTTPS PDFs. Trait features: - Read + Seek + Send + Sync supertrait bounds for rayon page-parallelism - len() returns total source length - read_range() returns Bytes for zero-copy slicing - prefetch() with no-op default (MmapSource overrides for MADV_SEQUENTIAL) MmapSource: - Memory-mapped file access via memmap2 - Applies MADV_SEQUENTIAL advice via prefetch() - Zero-copy read_range() using Bytes::copy_from_slice() - Fallback for platforms/filesystems where mmap fails FileSource: - Standard I/O implementation using std::fs::File - Read+Seek delegation to underlying File - read_range() uses try_clone() for thread-safe concurrent access Re-exports from pdftract-core::source::PdfSource. Verification note: notes/pdftract-1mmq9.md documents completion status. Parser module migration to use new PdfSource is deferred to follow-up.
