sami7777 426e23d8be Add clang-format, clang-tidy, ASan/UBSan CI lanes
Format and tidy enforce only on lines changed in PRs (diff-only via
git-clang-format and clang-tidy-diff.py) — existing files keep their
current style until edited. Mass reformat deferred; .git-blame-ignore-revs
stub is in place for whenever that happens.

Sanitizer lane builds with -fsanitize=address,undefined and runs the
unit suite. continue-on-error: true initially so we can triage findings
without blocking PRs. UB categories pervasive in the Hash9 C cascade
(alignment, signed-integer-overflow, vptr) are suppressed pending
file-by-file fixes.

# Triangles code style.
# Conservative: do not reflow long lines, do not reorganize includes.
# This config is enforced *only on changed lines* via `git clang-format` in CI,
# so it shapes new/edited code without touching legacy files until they're touched.
