P5a: digests cite pages; sift_pdf_* metrics; sift fetch --pages/--grep; skill, unit and README

Digest systemPrompt gains a page-cite instruction and PromptVersion is 3.
Add the sift_pdf_* metric series (extract_total{outcome}, extract_seconds,
pages_total, pool_wait_seconds, cache_hits_total) to internal/metrics and wire
ObservePDF/ObservePDFWait/PDFCacheHit into internal/api/pdf.go. Refactor
cmd/sift/fetchcmd.go to a fetchOpts struct with parseFetchOpts and fetchBody,
adding --pages/--grep. Update skill/SKILL.md, set nix MemoryMax to 1G, and add a
PDF documents section to the README.
