fix(core): handle ${} in getRoutePath and escaped tags in getRouteAsArray

getRoutePath: skip past ${...} block and continue processing remaining
suffix so later {param} segments are still converted.

getRouteAsArray: add (?<!\) to split/match regexes so jsesc-escaped
${...} is treated as literal text, preventing standalone backslash
from breaking single-quote wrapping.
