[eric] .swarm portable share/bundle feature + dashboard/chat UI polish

[ciregenz]

What this lands

.swarm portable share/bundle feature

A portable .swarm container for sharing OpenSwarm entities, with import treated as a proposal (no silent execution).

• .swarm bundle engine + skill export/import endpoints
• App export/import (workspace tree, .env regen) with code-safety review
• Dashboard export/import (closure of agents + apps + modes, two dependency classes)
• Workflow export/import (lazy store, schedule-off + PII-strip on import)
• Share buttons across Skills detail, app card/editor, and the dashboard header
• Drag-drop + file-picker import flow with a preflight/commit modal and an import review/trust warning; drop-to-import uses a GPU-safe pixel digest, modal only for code/action bundles
• Security tests: secret redaction, zip-slip / zip-bomb guards, skill round-trip

Dashboard + chat UI polish (this session)

• Dashboard header glyph is now derived from the title: a curated lucide icon by whole-word keyword (plural-aware), with a tinted-monogram fallback so a no-match title gets an honest initial instead of a misleading icon. New DashboardGlyph module.
• Thinking-verb lists deduped into one shared thinkingLabels.ts (the streaming pill and the per-message bubble had drifted into two copies), plus a batch of quirkier verbs with correct past tense for the finished-bubble case.

Notes

• Frontend typechecks clean.
• Base brought current via merge of origin/eric/dev (no conflicts).
• Draft on purpose: the .swarm import security path warrants a review pass before merge. Flip to ready when you're happy with it.
