ParseIdentitySelection (strict written form or base-10 decimal key,
optional [k] or [a-b]) and ParseNameSelection (name part may be empty,
no whitespace or brackets) apply the shared selection grammar and check
order (5.16 syntax, 5.14 width, 5.17 marked decimal without [k], 5.8
alignment only with [...], 5.7 element bound, 5.5 reversed), reporting
only the first failure with a rule tag and a message quoting the
selection. Runs the shared selection-cases table plus REST-only rows.
Not yet wired into the handlers.
