* csv: port CPython reader state machine

Replace the csv-core reader and per-item quote scanner with one Rust
implementation of CPython's nine-state reader parser. Keep parser state
across iterator items and distinguish virtual item boundaries from true
iterator exhaustion.

Centralize field completion so quote provenance, empty-field None conversion,
float conversion, strict parsing, field limits, blank rows, and escaped or
quoted newlines share one path. Apply the existing reentrant-iterator
generation check to every iterator item consumed by a record.

Also accept empty ASCII line terminators like CPython, report a missing
csv-core writer sentinel as _csv.Error instead of panicking, and name the
FSM entry point process_parser_input.

Remove the expected-failure markers from the eleven reader tests that now
pass.
