AlexandClaude Opus 4.7 2f646ee154 fix(husky): guard pre-commit against merge/rebase state
lint-staged uses git stash internally to isolate staged files for
linting. During a merge/rebase/cherry-pick/revert, that stash machinery
interacts catastrophically with MERGE_HEAD and friends — on any lint
failure it resets, silently wiping MERGE_HEAD and your conflict
resolutions. The user ends up in a loop where every merge attempt
leaves a clean tree with no merge commit.

This adds an early-exit guard for the four mid-operation states, and
also anchors the script to the repo root + scopes each lint-staged run
in a subshell so a subdir commit or per-package failure can't poison
the cwd for the next step.
