--resume, --from-pr and --worktree take an optional value in the Claude Code CLI (-r, --resume [value] in claude --help), but the extern declared them as string flags. A bare claude --resume, which is how you open the interactive session picker, therefore fails to parse:

Error: nu::parser::missing_flag_param
  x Missing flag argument.

Nushell flags can't have an optional value, so this declares the three as switches. An extern passes its arguments to the external command in the order they were typed, so a value after the switch still arrives where the CLI expects it:

claude --resume              => [--resume]
claude -r abc -p hi          => [--resume][abc][--print][hi]
claude -w feature            => [--worktree][feature]
claude --from-pr 123         => [--from-pr][123]
claude --remote-control desk => [--remote-control][desk]

(argv as received by a stub claude on PATH.) The one thing lost is the --resume=<id> spelling, which Nushell reads as a boolean on a switch; --resume <id> works.

Also:

• adds --remote-control, which was missing and takes an optional name in the same way
• refreshes the value lists against Claude Code 2.1.302: effort gains xhigh and max; permission-mode gains auto and manual and drops default, which the CLI no longer lists as a choice; models moves to the current aliases (fable, opus, sonnet, haiku) and model IDs

Tested on Nushell 0.116.1: toolkit.nu check pr on the file passes, and commandline complete returns the new lists for --effort, --permission-mode and --model.
