chore(claude): simplify commit skill to always use plain strings

[rekmarks]

Every time I ask Claude to commit, it errors one time due to using a HEREDOC, because it can't remember that it's sandboxed. No more.

Summary

• Remove conditional HEREDOC usage from commit skill
• Always use plain strings for commit messages

---

Note

Low Risk
Documentation-only change that updates the commit workflow guidance; no runtime behavior or production code is affected.

Overview
Simplifies the commit skill instructions in .claude/skills/commit/SKILL.md to always use a plain-string commit message, removing the prior conditional guidance to use a HEREDOC in non-sandboxed environments.
