fix(resolution): prevent duplicate org in trace ID resolution (#1289)

The `looksLikeSlug` function in `src/lib/hex-id-recovery.ts` was
incorrectly returning `true` for full target paths (e.g.,
`org/project/id`) because it only checked for alphanumeric characters
and dashes, not the presence of slashes.

This caused `buildSlugHint` to prepend the organization slug to an input
that already contained it, resulting in an invalid trace ID with a
duplicated organization segment (e.g., `org/org/project/id`). This
malformed ID then led to a `ResolutionError`.

This fix adds an early return to `looksLikeSlug` if the input string
contains a `/` character. This ensures that full paths are correctly
identified as not being bare slugs, preventing the erroneous prepending
of the organization slug and resolving the `ResolutionError`.
