Commit Message

fix: reject ULIDs outside the 128-bit range (#1660)

## Reject out-of-range ULID strings

The `ulid` tag currently accepts 26-character Base32 strings starting
with `8` or a letter, although the [ULID
specification](https://github.com/ulid/spec#overflow-errors-when-parsing-base32-strings)
limits the largest value to `7ZZZZZZZZZZZZZZZZZZZZZZZZZ`. Restrict the
first character to `0`–`7` and retain the existing case-insensitive
Crockford alphabet for the remaining characters.

The regression exercises `Validate.Var` and `Validate.Struct` across the
first-character alphabet, minimum/maximum values, case variants, length
boundaries and excluded letters. It fails against the original
implementation and passes with the change. Full `go test -race -count=1
-cover ./...`, `go vet ./...`, golangci-lint v2.13.1, formatting and
diff checks passed locally on Go 1.26.4/macOS; other Go versions and
platforms were not run locally.

- [x] Tests exist or have been written that cover this particular
change.
