ehoandClaude Opus 5 07bb6277c0 refactor(backend): extract brief guards into Domain/Letters/BriefRules.cs (RB-30)
BriefStore's five guard decisions (Save, Submit, Send, and the shared
Approve/Reject review path) were pure functions of status tag, actor role,
and entity completeness, but each sat inside a lock-held, DB-opening
method. A spec could not exercise the decision without a booted host and
a real SQLite file.

Extract the guards into a pure Domain/Letters/BriefRules.cs. BriefStore
keeps its lock, its Db.Create(), its static shape, and every method
signature — only the if cascades move. Add BriefRuleTests.cs (29
assertions, ~120 ms, no host boot) covering every branch, including the
rejected-to-draft reopen on save, the required-filled gate on submit,
and the non-drafter and self-review denials. The existing host-booting
brief endpoint tests are unchanged and still pass, proving the
extraction preserved behaviour.
