style: enable Biome formatter and format the codebase - #54
Merged
Conversation
Enable Biome's formatter (tabs, lineWidth 100) and apply it across the project. Pure formatting pass — no logic changes — normalizing the previously inconsistent mix of tabs and spaces between files. Scripts now use `biome check` (lint + format) so the formatter is enforced both in CI (`bun run lint`) and the pre-commit hook. 100 files reformatted. Verified: tsc exits 0, 246 tests pass. A follow-up commit registers this hash in .git-blame-ignore-revs so git blame skips the bulk reformat.
Register the bulk-formatting commit in .git-blame-ignore-revs so `git blame` and GitHub's blame view skip it and keep attributing each line to its real author instead of the reformat. Enable it locally with: git config blame.ignoreRevsFile .git-blame-ignore-revs

Summary
project — a pure formatting pass, no logic changes.
biome check(lint + format) so formatting is enforcedin CI and the pre-commit hook.
.git-blame-ignore-revsso the bulk reformat doesn't pollute blame.Why now
The project never had a formatter, so indentation was inconsistent
between files (some tabs, some spaces). Biome was already in place
from the linter migration, so enabling its formatter closes that gap.
Scope — this is large but mechanical
100 files reformatted (96 source + 4 config), +3928 / −3274. Every
change is whitespace/style only. Reviewing line-by-line is unnecessary;
the safety net is the verification below, and
git blameis protected.Blame protection
The formatting commit hash is registered in
