feat(tui): /version slash command for wizard + protocol version visibility

[kelsonpw]

Summary

Salvaged from #725 by cherry-picking its unique commit onto a fresh branch from main. The original PR was stacked on the closed feat/v2-tui-redesign (#696); its git history carried ~35 commits of v2 orchestration scaffolding that couldn't be rebased onto main's parallel orchestration implementation.

Original commits preserved: 8cf86032

Skipped: f6b09583 — this followup wraps process.exit in src/utils/wizard-abort.ts, which is on the salvage-policy "do not touch" list (load-bearing). The vitest unhandled-rejection bug it patches can be re-addressed in a dedicated PR if it surfaces on CI.

Notes:

• The /version commit also touched the slash-command registry to add /status and /help (from later v3 PRs). Only /version was kept — /status belongs to the orchestration overlay work and /help is salvaged separately in PR feat(tui): register /help command and accept Tab in slash palette #739.

Test plan

• tsc clean
• eslint clean
• pnpm build clean
• CI will run vitest + Bugbot

Note

Low Risk
Low risk: changes are isolated to TUI command registration/dispatch and add read-only version formatting with test coverage, without affecting auth, data writes, or run orchestration.

Overview
Adds a new read-only /version slash command to the TUI that surfaces wizard version, agent-mode wire protocol version, and Node/platform runtime info via getVersionText().

Wires /version into ConsoleView command dispatch (shown via setCommandFeedback) and extends unit/render tests to ensure the command stays registered and remains available mid-run.

Cursor Bugbot has reviewed your changes and found 1 potential issue.

Bugbot Autofix prepared a fix for the issue found in the latest run.

• ✅ Fixed: Version text renders as single blob, not separate lines
  • Split the getVersionText() return value with .split('\n') so setCommandFeedback receives a string[] array, giving each version line its own <Box> with proper indent prefix, matching how /diagnostics passes multi-line feedback.
