GigaMail 0.3.2

• Codex CLI as a first-class agent. The console detects codex next to
  claude, lets you pick the agent that writes the drafts (first-run guide
  and Automations), stores the choice as {"agent": "codex"} in
  agent.json and resolves the command at every start. Drafts run through
  codex exec in a read-only sandbox, with the final answer read from a
  file. The MCP registration snippet switches to ~/.codex/config.toml
  (or codex mcp add) when Codex is selected. Both directions verified on
  Windows — see INTEGRATIONS.md, including the gate holding with Codex's
  own approvals bypassed.
• .codex-plugin/plugin.json follows the release version (it was still
  0.2.4 at 0.3.1); sync-version.js and a test keep it aligned.
• Attachments open again from the console. Clicking an attachment
  answered "HTTP 404" on every account: the console asked the backend for
  GET /mail/{id}/attachment/{name} and that route did not exist. It
  does now (bytes, content type from the provider or from the file name,
  proper Content-Disposition), with tests.
• An old notification says it is old. Pressing a desktop toast after
  its request has expired or been decided used to answer "request does
  not exist", which reads like a fault. It now says the notification is
  stale and lists what is actually waiting, if anything; and the window
  no longer dies with a traceback when there is no standard input.
