feat(rust): per-split facet digest -- KB-scale facet pricing boot (Rust half)

New summary TLV (tag 3): a per-split facet digest -- the top-k categories
per field by full-corpus count, with names, counts, and posting ranges,
derived from the emitted sidecar's own bytes so ranges match exactly.

- builders: with_facet_digest(top_per_field) on both split builders emits
  the digest at seal, after the presence TLV; 0 (default) emits nothing and
  keeps every existing manifest byte-identical
- reader: facet_counts/facet_counts_for price from the resident digest when
  it can serve the request (cap within the digest's k; every named pair
  either in the digest or provably absent per the facet-presence summary,
  which prices to 0 with no fetch); any miss falls back to open_meta, so
  results never depend on the digest -- old readers skip the unknown tag
- for a high-cardinality sidecar this removes the whole-meta boot (measured
  ~2.3MB per split, ~60% of a first-touch facet wave) from the pricing path

Tests: codec round-trip + pricing parity vs the full meta; digest-carrying
manifests (hand-built and builder-built) price with zero .rrf offset-0
reads; uncapped pricing and long-tail pairs fall back; provably-absent
pairs price 0 fetch-free.

Go writer mirror + shared conformance golden land next.
