ADR-0024 Phase F (full) step 4: catalog token-keyword cleanup

Drops the 47 `parse.token.keyword.*` and 6 `parse.token.punct.*`
catalog entries (and their `KEYS_AND_PLACEHOLDERS` declarations).
Nothing consumes them: the walker renders keyword wording in
`format!(\"`{word}`\")` directly, sourced from grammar-tree Word
literals; punct wording surfaces the same way via
`Expectation::Punct(ch)`.

Structural-class labels (`parse.token.identifier`,
`parse.token.number`, `parse.token.string_literal`,
`parse.token.flag`, `parse.token.end_of_input`) and the lex-error
wordings (`parse.token.error.{bad_flag,unknown_char,
unterminated_string}`) stay. These are not derivable from the
grammar tree and the walker's expected-set / validator paths still
read them.

`friendly::keys::tests::keys_validate_against_catalog` continues to
assert catalog ↔ `KEYS_AND_PLACEHOLDERS` bidirectional coverage,
so the trimmed declaration is pinned against the trimmed catalog.

Tests: 806 passing, 0 failing, 1 ignored. Clippy clean.
