* ci: add Pi+DeepSeek-V4 review and slash command dispatcher
Auto-reviews now fan out to Claude (Opus), Codex (gpt-5.4), and Pi
(DeepSeek-V4-Pro) on PR open/ready. PR comments support /review (all
three), /codex, /pi, /claude with optional extra context appended to
the prompt. All review workflows now substitute EE code before review
and gate the auto-trigger path on org membership of the PR author.

* ci: fix command parser whitespace, align checkout v5, broaden PR perms
- Trim leading/trailing whitespace from comment first line so /review
with leading space parses correctly (caught by Pi review)
- Standardize EE checkout step on actions/checkout@v5 across all three
review workflows (caught by Pi review)
- Bump pull-requests permission to write to satisfy GitHub's PR
comment endpoint when issues=write alone is rejected
