Don't offer adding a trailer in a rebase or a cherry-pick or reverts

[Soph]

Did a long rebase today, and a few commits in between had no trailer, so our hooks offered to add a trailer. This shouldn't be done in context of rebase, revert or cherry-pick

---

Note

Prevents adding Entire-Checkpoint trailers when Git is replaying commits.

• Introduces isGitSequenceOperation() to detect rebase-merge, rebase-apply, CHERRY_PICK_HEAD, and REVERT_HEAD using GetGitDir() (supports worktrees)
• Updates PrepareCommitMsg to no-op with debug logging during these sequence operations
• Adds tests for detection in clean repos, rebase-merge, rebase-apply, cherry-pick, revert, and worktrees in hooks_test.go

Pull request overview

This PR prevents the CLI from offering to add Entire-Checkpoint trailers during git sequence operations (rebase, cherry-pick, revert). These operations replay existing commits and shouldn't be linked to agent sessions. The implementation adds a detection function that checks for git state files/directories and returns early from PrepareCommitMsg() when such operations are in progress.

Changes:

• Added isGitSequenceOperation() function to detect rebase/cherry-pick/revert state
• Modified PrepareCommitMsg() to skip trailer addition during sequence operations
• Added comprehensive unit tests covering all sequence operation types and worktree scenarios
