`scripts/soma-attr-audit.ts` compiles every morfo and flags attrs a provider
hardcodes in its props getter that the morfo already declares with a resolvable
value (segmenting the provider by `runtime.part('<kebab>')` to map getter→part).
Measures the migration backlog and catches new drift.
Current backlog: 607 hits across 50 components (worst: words 49, dropdown/context
menus ~28, combobox/command/time-field ~24). The migrated spin-field family is
down to its legitimate residue — number-field 1, css-field 2 (formatted
aria-valuetext, parsed aria-valuenow — values the morfo can't express).
`soma-attr-audit.test.ts` pins each migrated component to its legit-override
ceiling so it can't regress to hardcoded attrs. Extend the ceiling map as more
components migrate.
