id: one line grammar for SSH command mode, the id world join pump and CLI verbs (--command-mode) #546

What and why

The line grammar should mirror the id world subcommands (chat, records, stats, logs, caps, quit), so the same sentence works as an SSH command, a piped script line and a CLI one-off. The id world join stdin pump should gain the same grammar and an explicit --command-mode flag. The same sentence should work as an SSH command, a piped script line and a CLI one-off. Today the three surfaces each know a different subset.

Current status

Partial. SSH command mode supports only /help, /quit, /records, /documents, /document, /input (pkgs/id/src/world_ssh.rs:620-668 world_command), with no /stats, /logs or /caps. The join pump knows only /quit and /input (pkgs/id/src/commands/world.rs:1005-1006). There is no command-mode flag in pkgs/id/src/cli.rs.

Acceptance criteria

• A short plan fixes the grammar, mirroring the id world subcommands (chat, records, stats, logs, caps, quit)
• SSH command mode supports /stats, /logs and /caps
• The id world join stdin pump parses the same grammar, behind an explicit --command-mode flag
• One shared parser, with tests that the same line yields the same action on SSH, the pump and the CLI
