v0.19.0

bv v0.19.0

Features

• --robot-triage --brief (#183): compact triage output mode for agents that
  only need the headline recommendations, not the full analysis payload.
• Comments in Pages export (#187): the static Pages export now renders bead
  comment threads, so exported boards carry the full discussion context.

Fixes

• Robot-surface agreement / agent-safety (#184): --robot-file-hotspots,
  --robot-file-beads, and --robot-impact disagreed for the same path
  (3 vs 0 vs "safe to proceed"). File-touching bead counts are now unified
  across all three surfaces — no more false "safe to proceed" verdicts
  steering agents into files with open beads.
• Theme override completion: reliable --theme light|dark selection for
  light terminals (bv-128).
• Fail-closed robot-next claims: --robot-next claimability no longer
  fails open (bd-ifoh3.3).
• Export memory (#182): history blobs stream with bounded memory; caches
  enabled off-robot.
• Gitignore hygiene (#179): prefers .git/info/exclude and adds a
  BV_NO_GITIGNORE opt-out.
• Viewer: routes host-rewritten clean paths and guards double WASM init on
  direct graph entry.
