feat(workspace): claudemesh me search + dashboard parity

ships v0.4.0 phase 5 — final aggregating verb. v0.4.0 substrate
is complete after this.

api: GET /v1/me/search?q=... matches against topic names +
sender display names + v1 message snippets (base64 decode then
ilike). v2 ciphertext matches only on topic/sender — server has
no topic keys. 30-day window on messages, capped at 50 hits per
category.

cli (1.14.0): claudemesh me search <query> renders topic + msg
sections with inline yellow highlighting. min 2 chars; --json
returns the raw response.

web: /dashboard/search adds an autofocused input + mark
highlighting on every match site (topic name, sender, snippet).
sidebar gets a search entry between activity and invites.

roadmap: phase 5 marked shipped, v0.5.0 default-aggregation
behavior added as the natural next track.
