#1069 Add a no-second-person rule to the lede-voice doctrine

[williamthorsen]

What

Agents composing changelog and release-notes entries are now instructed not to use the second person.

Why

Ledes across two repositories repeatedly slipped into second-person address, which reads as a product tour rather than a release note and leaves the referent ambiguous. The doctrine demonstrated the third-person register in every worked example but stated no rule, so a draft could address an unidentified reader and still pass a self-audit.

Details

🎉 Features

• A fourth rule in the lede-voice doctrine prohibiting second-person address, placed with the other per-sentence rules so it sits alongside the outcome, identifier, and redundancy tests. Stated in a single sentence, with no rationale or example pair — the doctrine's fifteen existing worked examples already model the register.
• Mirroring the rule into the shared voice checklist (which reaches the commit and merge-pr skills), adding a rule line to the changelog-writer audit-output template, and constraining the person of the summarize-change dispatch input are all deliberately deferred, so a later round can tell whether the doctrine alone sufficed.
