feat: add $derive.type to convert derived values to non-string types

A $derive.pattern extracts a regular expression capture, so its result was
always a string. Since $filter compares strictly by type, such a value could
never match a numeric or boolean field: "2024" does not equal 2024, and the
ordering operators require both sides to be numbers. Configurations had to
carry a shadow string field and fall back to `contains` to work around it.

$derive now accepts an optional `type` (string, int, float, bool, auto) that
converts the extracted value. The conversion runs before deduplication, so
values of different kinds no longer collide into duplicate path segments, and
$filter substitution already preserves the JSON type of an exact `{var}`
token, so filter.rs needs no change.

Omitting `type` performs no conversion and keeps the pre-0.0.4 behavior.
Values that fail to convert are skipped and reported with the existing
non-derivable warning rather than aborting the build.

`auto` is deliberately conservative: it converts only booleans and integers
that round-trip losslessly, so identifier-like strings such as "007" keep
their leading zeros in the generated path.
