# Description of Changes
Fixes one of the main causes of `any` typing left in tools, the way that
we register tool parameters in the registry. Currently, it just accepts
tool params via `any`, but instead we can explicitly change them to
`Record<string, unknown)`, so on the way back out they can more safely
be cast back to their correct type when known.
One consequence of this is that I had to redesign the way we
special-case the Convert tool, which previously was a different shape
than all the other param types. Now it's just got optional parameters on
it, which isn't quite as type-safe as before, but it does mean all tools
are a consistent shape now, which I think is worth the tradeoff.
# Description of Changes
Adds all the missing translations that I could find (they're all dynamic
ones that the existing test can't detect are required) and adds a new
test to find as many unused translations as possible. The test has an
ignore list for translations that are used, but dynamically so the test
can't find them (most of the settings UI translations are built up
dynamically like that).
This PR is scoped to just include en-GB translation changes, since
that's the main supported language. We'll need to do a translation PR to
trim all the dead keys from the other languages, and add the missing
ones.
