The Claude adapter dropped the compact_boundary system frame, so a /compact turn ended with no transcript content and the ring kept the pre-compaction size until the next reply. Emit a "Context compacted." note (as Codex does) and ContextUsage from post_tokens (as Pi does). Fixes zeronsh#801

Fixes #801.
Problem
In a Claude Code chat,
/compactcompacts the session, but Zeron shows nothing. The turn ends with no transcript content, and the context ring keeps the old size until the next reply. The Claude normalizer drops thecompact_boundarysystem frame. A/compactturn also has no assistant frame, which is the only place the Claude adapter setsContextUsage.tokens.Change
On
system/compact_boundary, the Claude normalizer now emits:TextDelta("Context compacted."), thenAssistantMessageCompleted, so the note is its own message and any text after an auto-compaction starts fresh. This matches Codex'scontextCompactionnote.ContextUsage { tokens: compact_metadata.post_tokens }when the CLI sends it. This matches Pi'scompaction_end.No protocol or UI change.

claude/normalize.rs. This change sits in theFrame::Systemarm, so any conflict should be small.Need help on this PR? Tag
