Tribunal and judgment dialects join the tables, mined not invented

cite.neutral.tribunal: a closed 13-member enum of the multi-token
court codes A2AJ providers actually attest (Comp Trib / Trib conc /
CIRB LD families - 1.87M citation cells, 26 MB of judgment prose, and
3.5M CanLII ids mined; every generic widening measured 6-9 false
positives, the enum 0). Closes the last recall gap: CT/fr 94.6 ->
100.0, Competition Tribunal now 552/552. cite.statute.judgment(.fr):
the anchors' own STATUTE_CANADIAN(_FR)_RE extracted verbatim - the
judgment dialect the footnote lineage scores 0% on, perfectly
complementary (89% of dotted/'c.', 76% of dotted/'ch.'), span-parity
0 mismatches over 4,350 documents. Residual 23.8% documented by cause
(chap., EN-series+ch., S.R.C. et al) - source-side questions, not
table patches. Agent's null-group vector expectations trimmed: they
pass Python's groupdict but fail JS (undefined !== null); both
runtimes green, 16 tests.
