chore(sdk): bump go-flashduty and regenerate CLI surface

Picks up go-flashduty 4d5816a (PR #31), which regenerates the SDK from the
corrected monit OpenAPI spec (flashduty-docs #190).

monit contract — the reason for this bump:
  monit-webapi d0d1ef4 turned /monit/tools/invoke and /monit/tools/catalog
  into sparse-field responses (omit instead of null) and flattened the
  single-tool result envelope. The CLI's generated response-help still
  documented the old nested/nullable shape, telling callers to expect
  "data": null and "error": null placeholders that the server no longer
  sends. Now aligned: data/summary/truncated/tool_version/error/target/
  target_kinds/next_cursor/output_shape are all documented as present-only.

Carried along — unrelated SDK work already merged upstream that this regen
necessarily picks up (the dep bump and the regen must be one commit or CI's
cligen drift check fails):

  New commands
    flashduty licenses ...
    flashduty session-replay ...

  Breaking flag changes
    a2a-agent create/update: --description removed, --instructions now
      required (the API deprecated description in favour of instructions)
    session list/info: entry_kind enum value scheduled -> automation

  New flags
    a2a-agent: --allow-insecure-oauth-http, --allow-insecure-tls-skip-verify,
      --environment-id, --environment-kind, --query
    a2a-agent list: --scope enum all|personal|team -> all|account|team
    automation create: --cron-expr no longer marked required

Cards regenerated via `make gen-cards`; monit-agent.md / monit.md are
unchanged here because PR #91 already landed those fixes.

make check green: gofmt+gci clean, golangci-lint 0 issues, go test -race all
packages ok, build ok.
