v0.8.8

A session can now ask someone in a Feishu chat a question and get the answer
later, and the main session hands long work to jobs so the next person who
writes to it is not kept waiting.

Upgrading means reinstalling core (0.8.8) and the Feishu channel (0.8.8), then
restarting the daemon and every Feishu instance. Protocol (0.8.6) and the ACP
channel (0.8.3) are unchanged. The bundled agent SDK moves to ^0.3.318
(Claude Code 2.1.318); pi moves to 1.5.0.

Behaviour changes to know about:

• The main session dispatches long work. Work that would keep main busy
  for minutes — a build, a multi-step change, research — goes to a job that
  notifies main with the result; quick work stays in main. For a request from
  a forwarded chat, main leaves the message's received mark in place until the
  result is back, then answers it with send --reply-to. The first turn after
  the upgrade pays the one-time cost of a role-text change.
• Subagent effort (Claude Code 2.1.317). A subagent running on a model
  other than its session's uses that model's own effort setting or its
  default, not the session's. CLAUDE_CODE_SUBAGENT_EFFORT sets it.
• pi 1.5.0 tightened its system prompt. The tools section pi sessions keep
  in override mode now ends with "Additional tools may be available."

Features

• Ask a chat with a question card. duoduo channel feishu ask --chat <chat_id> --who <@name|owner|anyone|ou_…> --question "<text>" --context "<text>|-" posts a card with buttons (--option, once per choice), a
  multi-select (--multi), a text field (--text <label>), or a mix. The
  first valid answer replaces the card for everyone with the question, every
  option offered (the chosen ones marked) and, in a group, who answered. The
  answer returns to the asking session as a notification carrying its
  --context, so the session ends its turn after asking. A card for the
  owner, or for a name that matches nobody or several people, goes to the
  owner's direct messages with a line naming the session and the chat. Cards
  expire after 14 days, or sooner with --expires. Only a chat's forward
  target or the chat's own session can ask there; ask from a terminal is
  refused. ask --help explains the rest. Card text follows
  FEISHU_LOCALE (Chinese or English).

Security

• Dependency advisories cleared. follow-redirects moves to 1.16.2
  (GHSA-mrwp-f3q8-3g9p, high; reached through the Feishu SDK's HTTP client).
  pi 1.5.0 pins undici 8.12.3, so the undici 8.10.2 copy noted in v0.8.7 is
  gone.

Updates

• Agent SDK 0.3.318 (Claude Code 2.1.318). See the behaviour changes above.
• pi 1.5.0. Tool arguments are validated by pi's own schema library; the
  new sibling package @earendil-works/pi-schema is pinned with the rest.
