The --chapters filter compared the raw CLI token by exact string
equality against the zero-padded chapter tags ("01".."22") that
the corpus carries (roman_to_padded, src/claml.rs). The CLI only
split and trimmed the input, so the intuitive forms — `--chapters 4`
or `--chapters E,I` — never matched any candidate and the suggestion
list came back empty, indistinguishable from "no clinical match".
Add a pure `normalize_chapters` helper that zero-pads bare 1-2 digit
chapter numbers to two digits and partitions the token list into
known chapters (1..=22) and unrecognised tokens. The Suggest arm now
feeds the padded set into the filter and emits a stderr warning for
each unrecognised token, so misuse is visible instead of silent.
`--chapters 4` and `--chapters 04` now behave identically. ICD
code-letter mapping (E -> chapter) is deliberately left out of scope:
under this contract a letter is simply an unrecognised token and
triggers the warning.
