v0.5.118 — Ambient tmux recovery and follow-up delivery

What's changed

• #326 — Smooth Leader startup from tmux: adaptively isolate inherited foreign or unavailable ambient pane context into a workspace-owned managed launch. Explicit external/attach authority checks remain strict; unrelated panes are not adopted or rewritten.
• #328 — Cursor follow-up delivery: recognize the current Add a follow-up viewport after startup banners leave scrollback, including expanded multiline editors, so follow-up messages reach the normal Enter submission path.
• #331 / #321 — Restore unconditional legacy input: remove regressive pre-paste idle admission and restore v0.5.113 paste-and-submit behavior instead of indefinitely deferring messages while waiting for an idle composer.
• Align the installer, Rust workspace and all three native platform packages at 0.5.118.

Validation scope

Independent finite basic-function smoke covers three provider catalogs and a real Pi Leader/Pi Worker startup, message delivery, natural worker-originated CLI inbox reply and scoped shutdown. The fixture's preliminary role/response-channel calibration is retained in its report. This is not an unrestricted provider/model/state matrix.

Official CI verifies workspace tests, controlled macOS root/contract fixtures, Clippy and scoped formatting; the tagged publishing workflow rebuilds all three native platforms before npm publication.
