Expand description

Phase 8c: a single FTS posting-list cell. Body layout (after the shared cell_length | kind_tag prefix):

  cell_id    zigzag varint   sequential id assigned at save time;
                             acts as the B-Tree slot key so
                             `peek_rowid` works uniformly
  term_len   varint          length of the term in bytes
                             (0 → this cell is the doc-lengths
                             sidecar, value below is doc_len)
  term       term_len bytes  ASCII-lowercased term (per Phase 8 Q3)
  count      varint          number of (rowid, value) pairs
  for each:
    rowid    zigzag varint   the row this posting refers to
    value    varint          term frequency for this (term, row),
                             or doc length when term_len == 0

One sidecar cell with term_len == 0 holds (rowid, doc_len) pairs so reload reproduces every indexed doc — including any with zero-token text — without re-tokenizing. All remaining cells are posting cells, one per term.
