Add a --brief flag that lists cheatsheets with only title and tags,
omitting the file path column. Can be used standalone (-b) or combined
with --list (-lb), and composes with existing filters (-t, -p).

Previously cheat only checked the current working directory for a .cheat
subdirectory. Now it walks upward through ancestor directories, stopping
at the first .cheat directory found. This mirrors how git discovers .git
directories, so users can place .cheat at their project root and have it
work from any subdirectory.

Move `doc/adr/` to `adr/` for discoverability. Remove the generic
ADR README — `ls adr/` serves the same purpose.
