feat(plugin): /wt-switch-create — optional repo arg and -- task delimiter

[max-sixty]

The /wt-switch-create skill now accepts <branch> [<repo>] [-- <task>]. The optional second token names a different repository to create the worktree in (instead of the session's current one); the skill cds into that repo with a Bash call before invoking EnterWorktree (which has no repo parameter), then verifies the new worktree landed under the requested repo as a safety check.

The -- cleanly separates the task from the rest. Without one, the parser treats a path-shaped second token (absolute, ~-relative, .//../-relative, or an existing directory) as the repo and the remaining tokens as the task — anything else after the branch is task text, so the old shorthand /wt-switch-create my-branch fix the bug keeps working.

Examples in the skill:

/wt-switch-create my-feature -- fix the parser bug
/wt-switch-create my-feature ~/workspace/other-repo -- fix the parser bug
/wt-switch-create my-feature

Also tidied existing prose: the nesting + different-repo case now stops rather than silently running the task in the wrong repo, and the scope note mentions the repo arg.

The follow-up commit updates the public docs page (docs/content/claude-code.md) so the /wt-switch-create signature shown at worktrunk.dev matches the new grammar; skills/worktrunk/reference/claude-code.md re-synced via test_docs_are_in_sync.

No code or test changes.

The skill grammar reads cleanly and the new safety check for the nested-different-repo case is a nice catch.

One out-of-diff observation: docs/content/claude-code.md still describes the command as `/wt-switch-create <branch> [task...]`, which won't reflect the new optional repo arg or -- delimiter after this lands. Since that file is the primary source for skills/worktrunk/reference/claude-code.md via test_docs_are_in_sync, the published docs page will lag the skill. Happy to push a follow-up commit updating the public docs page if useful.

Thanks — pushed 1eec508 updating docs/content/claude-code.md (and the synced skills/worktrunk/reference/claude-code.md) to show the new <branch> [<repo>] [-- <task>] signature. PR description updated to mention the docs follow-up.
