Problem

The engine currently assumes 1962. Supporting 1954 and 1955 requires a rubric-system parameter carried through temporal fill, overlay, and precedence so behaviour varies by system without forking code.

Acceptance criteria

day() accepts a rubric-system selector with 1954/1955/1962 values
The selector is threaded through all three resolver phases
Unknown systems raise a typed error
Existing 1962 tests pass unchanged with the default selector

Notes

Keep the core rubric-generic; no system-specific branches in shared code.
