feat(tools): L10 ludic-fmt enforces a project's style

lint lines in package.ludic - one_statement, max_file_lines, max_function_lines,
max_comment_lines, max_header_lines, paths, baseline - checked by ludic-fmt --check
<files> and ludic-fmt --lint (the project), at the line; a baseline ratchet lets a
rule arrive in a codebase that breaks it (--init-baseline), lowered as it is fixed.
check-impl reads the alias declarations too (it had been blind to every namespace
L6 moved out of the compiler), and eight methods get their pages; a test holds the
formatter to keeping type arguments together (L5).
