jrklaus8 starts wiring Mike into Canadian case law

jrklaus8's fork builds the scaffolding for Mike to search and cite Canadian sources: federal legislation from Justice Canada, and case law from CanLII, the free public database of Canadian court decisions. Citations to Canadian legislation now get their own card in the document panel, flagged with a maple leaf, and the chat can reach out to a case-law search tool to pull a decision by its citation.

The catch, which jrklaus8 is upfront about: the search and lookup currently return a couple of hardcoded sample cases, not live results. The code itself flags that real CanLII credentials are needed before this does anything for a practising lawyer. There's some cosmetic polish too - a frosted-glass landing panel and animated chat bubbles - but the real story is the Canadian-research ambition, not the styling.
