Deletions only; no behavior change except that the server no longer
recognizes query or drop <number>, both of which only ever returned an
error.

  • explain: drop the test-only second RowModel (nested_contract), the
    backstop test for a gap that is now implemented, and the invert fast path
    that Val never took (lossy_try_invert always returned None).
  • server: drop the reserved query command, the numeric form of drop, and
    the README note calling explain unimplemented.
  • Comments that describe history or no longer match the code: the retired
    flat [i64] model, rows_to_batch, vec::evaluate, a shape pass and
    design doc that don't exist, a test that doesn't exist, the chunker
    accumulating to TARGET (it is INGEST), probing costing n log n, the
    exchange/arrangement agreeing on primitive key ids, and a fused doc comment
    in chunk.rs.

Validation: workspace tests pass; clippy warning count unchanged.

Deletions only; no behavior change except that the server no longer
recognizes `query` or `drop <number>`, both of which only ever returned an
error.

- explain: drop the test-only second `RowModel` (`nested_contract`), the
  `backstop` test for a gap that is now implemented, and the invert fast path
  that `Val` never took (`lossy_try_invert` always returned `None`).
- server: drop the reserved `query` command, the numeric form of `drop`, and
  the README note calling `explain` unimplemented.
- Comments that describe history or no longer match the code: the retired
  flat `[i64]` model, `rows_to_batch`, `vec::evaluate`, a shape pass and
  design doc that don't exist, a test that doesn't exist, the chunker
  accumulating to `TARGET` (it is `INGEST`), probing costing `n log n`, the
  exchange/arrangement agreeing on primitive key ids, and a fused doc comment
  in chunk.rs.
