uploads-v0.9.0

Minor Changes

• d67c093: uploads put now stamps the four gh.* metadata pairs whenever it has a
  GitHub target, so screenshots hosted on the default screenshots/… path get an
  "Attached to" link on their /f/ page. On by default: with --pr/--issue
  the explicit target is used (previously the stable key was written without
  metadata); otherwise put resolves the current branch's PR (or classifies a
  numeric --ref as pull vs issue) via gh. Disable with --no-auto,
  --no-git, or UPLOADS_NO_AUTO_META=1. Resolution is best-effort — a missing
  gh, no PR, or an API error uploads normally without metadata.

Patch Changes

• 528d895: Metadata discoverability polish: uploads find / list --meta now print each
  match's matched metadata inline in human output (as LIST_HELP already
  promised, previously only in --json); uploads meta get on an object with no
  metadata prints a (no metadata) note to stderr instead of nothing; and
  uploads attach prints a find these later: uploads find gh.ref=… hint so its
  auto-written gh.* metadata is discoverable. README now lists the stdio MCP
  set_metadata/find_files tools and the put/attach metadata param.
