🤖 fix: clarify workflow slash command hints

[ThomasK33]

Summary

Clarifies the Workflows sidebar empty-state copy and /workflow slash-command ghost hint so both describe explicit workflow script-path invocation without implying a special workspace workflow directory.

Background

The previous sidebar text pointed users at .mux/workflows/, but workspace-file workflows are not discovered from that folder. They are loaded by explicit .js path, while the Workflows tab only lists workflow-bearing skills with a conventional workflow.js entry. The slash-command ghost hint also repeated /workflow after the user had already typed it.

Implementation

• Added a canonical workflow slash-command argument hint: <script_path> [args].
• Reused that hint for the /workflow command usage, ghost text, and Workflows tab helper copy.
• Added a regression test that verifies the ghost hint shows only arguments after /workflow .

Validation

• bun test src/browser/utils/slashCommands/ghostHint.test.ts
• bun test src/browser/utils/slashCommands/parser.test.ts
• bun x prettier --check src/common/constants/slashCommandHints.ts src/browser/utils/slashCommands/registry.ts src/browser/utils/slashCommands/ghostHint.test.ts src/browser/features/RightSidebar/Workflows/WorkflowEmptyState.tsx
• make typecheck
• env MUX_ESLINT_CONCURRENCY=1 make lint
• env MUX_ESLINT_CONCURRENCY=1 make static-check
• Dogfooded in an isolated make dev-server-sandbox session with Agent Browser; captured screenshot and WebM evidence for the updated Workflows tab copy and slash-command hint.

Risks

Low. This changes display copy and shared command hint constants only; workflow resolution and execution behavior are unchanged.

Addressed Codex finding PRRT_kwDOPxxmWM6MPYUs:

• Updated the workflow ghost-hint regression test to assert the user-visible suffix directly (<script_path> [args]).
• Added an explicit guard that the returned hint does not include /workflow, preventing the duplicated command regression from returning.
• Re-ran bun test src/browser/utils/slashCommands/ghostHint.test.ts and env MUX_ESLINT_CONCURRENCY=1 make static-check successfully.
