Discrawl v0.11.0

Changes

• Add optional turbovec semantic-search scoring via [search.embeddings].vector_backend, while keeping exact cosine as the default backend. Thanks @vincentkoc.
• Added the Homebrew install command to the discrawl.sh landing hero and agent docs index, with a one-row desktop layout and copy button.
• Update crawlkit through v0.12.0.
• Add read-only Cloudflare remote archive scaffolding with [remote] config,
  subscribe-cloud, GitHub-backed remote login with OAuth or token-env
  bootstrap, remote status, remote archives, and cloud-mode status --json
  output that does not open or create a local SQLite database.
• Route cloud-mode search and filtered messages reads to Worker named
  queries so subscribers can inspect live D1 data without local SQLite.
• Add discrawl cloud publish to export non-DM local SQLite rows into the
  Cloudflare remote archive ingest API without changing Git snapshot
  publishing.
• Mirror the non-DM local SQLite archive into the Worker-backed R2 object store
  during discrawl cloud publish, alongside the D1 row ingest used for live
  queries.
• Compress the sanitized SQLite mirror as a gzip chunk bundle with an explicit
  privacy/count manifest before uploading to R2.

Fixes

• Kept resumed sync --full backfills from moving channel latest-message checkpoints backward, avoiding duplicate head recrawls on large interrupted channels. Thanks @hannesrudolph.
• Made messages --sync fail fast with an omit---sync hint when a live tail process owns the sync lock, while plain messages reads continue without waiting. Thanks @jeanmonet.
