feat(cli): colitur rubrics prints the day's Mass formulary

Separate from day for the reason readings is: a formulary name contains
spaces and day's row is space-separated with a variable-length tail.

Modelled on readings' own structure (year parsing, --overlay plumbing,
error handling): --overlay is accepted, since an overlay can change
which celebration is observed and hence which Mass is said. --lang,
--raw and --sigla-* are refused rather than silently ignored -- this
row resolves no display name and no citation for any of them to
affect.

Output is TAB-separated (date, formulary slug, source), not space or
" | " like the two existing reports: a resolved formulary NAME is a
column a later task may add, and it can carry both spaces and
punctuation a citation never does, ruling out either separator already
in use.

day and readings verified byte-identical (sha256) against a v0.10.1
build across 1583/1900/2026/2038/9999. Man page documents rubrics
beside readings and renders through groff with no errors.
