macOS: keybinding hint shows 'meta+w' instead of 'Option+w' (⌥W)

Summary

When the workflow trigger fires, the UI displays a dismissal hint as meta+w. On macOS, the meta key does not exist — meta is a Linux/X11 convention (Windows/Super key). The correct Mac label is Option (⌥), so the hint should read ⌥W or Option+W.

Steps to reproduce

1. Type a message that contains the word "workflow" (e.g. a bug report mentioning the feature)
2. Observe the notification banner: Dynamic workflow requested for this turn · meta+w to ignore

Expected behavior

• The hint should display ⌥W or Option+W on macOS, not meta+w
• Ideally: platform-adaptive labels (Cmd/Ctrl, Option/Alt, etc.)

Actual behavior

meta+w to ignore — the meta key is not labeled on any Mac keyboard, leaving the user unable to find the key without prior knowledge of the Linux key alias.

Related UX issue

The "workflow" trigger fires on any message containing the word "workflow", including casual mentions, bug reports, or questions. In this case, the user was filing a bug report that mentioned the word — not requesting a workflow. The trigger should likely require more explicit intent (e.g. a slash command or clearer phrasing) rather than a bare keyword match.
