Description 566 -> 249 chars, body 644 -> 398 words, Gotchas 12 -> 2. The
eight organisational hard rules move to references/hard-rules.md.
Its load trigger enumerates operations rather than rule topics: the first
draft keyed on 'commit message form', which left the atomicity and
working-state rules unreachable when a caller supplied a conventional
message. Also promotes the destructive-op confirmation ahead of the
orchestrator invocation, which it previously followed.
## Why
The git plugin only covered a partial slice of common git workflows.
This adds the remaining skill set (branches, commits, history, remotes,
submodules, workflow, worktrees) plus a git-orchestrate agent so the
plugin can handle end-to-end git automation instead of a handful of
commands.
## Implementation Notes
Each new skill was validated against its research docs and org
conventions after initial authoring, which surfaced hallucinated
version pins, factual errors, and completeness gaps that were
corrected in the same pass rather than left for follow-up.
## Impact
Bumps the git plugin to 1.3.0.
