Margins v0.4.2

Margins 0.4.2 makes recall and capture workflows feel native from anywhere in
an Obsidian vault.

• margins recall now mirrors enzyme catalyze: interactive terminals show
  the activated-bridge and surfaced-note tree, while pipes and agent capture
  retain the compatible JSON envelope.
• margins, margins new, margins setup, and margins recall discover the
  containing vault when invoked from nested folders such as inbox/.
• A completed margins new session now points users through workspace setup
  before Claude distillation when recall has not been initialized yet.
• Direct fallback results remain visible in the interactive recall tree even
  when no catalyst bridge is available.

Official binaries include the complete recording and recall composition. The
public open-core source remains available for audit and extension; capture and
workspace contents remain local to the installed application.
