docs: sync to current state of the world

claude.md scratchpad rewritten — folds in pronouns option,
extra MCP servers + flakeInputs forwarding, ask_operator
on sub-agents, dashboard compose box with @-mentions, new-
session button, cwd=/state for claude turns, meta-mutex +
stale-lock cleanup.

readme picks up the operator pronouns option example,
the dashboard compose box description, the new slash
commands list, the deployed-sha chip, the per-agent UI
gains new-session.

docs/web-ui.md gains:
- a fuller MESS4GE FL0W description that calls out the
  compose box, sticky @-mention recipient, /op-send, and
  the manager-name swap
- /op-send in the dashboard endpoint table
- new-session button + /new-session slash command in the
  per-agent surface
- compact endpoint now notes 'same session shape as a normal
  turn'

docs/turn-loop.md:
- new-session one-shot, cwd=/state with CLAUDE.md auto-load
  walking upward, operator-pronouns substitution
- sub-agent tool list grows ask_operator
- new 'Extra MCP servers (per-agent)' section documenting
  hyperhive.extraMcpServers + the flakeInputs forwarding
  pattern
