feat(hooks): hard-deny the AskUserQuestion popup machine-wide

The no-popup-menus rule in interaction.md was too easy to forget, so the popup kept slipping back into choice prompts. I added a PreToolUse hook on AskUserQuestion that denies the call outright and returns the rule as the reason, which routes choices back to inline numbered lists. Since ~/.claude/settings.json symlinks to this repo's .claude/settings.json, the hook is machine-wide and version-controlled across machines.

I documented it under the rule in interaction.md, including the consequence: the deny is unconditional, so the old "use the popup for this one" exception now needs the hook disabled via /hooks first.

 This rule applies to all three approval gates in the `commits.md` publish flow (commit message, PR description, PR review reply): print the draft inline, then offer numbered approve / changes / edit options inline. Do not switch to the popup form for the gate even though the prior protocol referenced it.
 
+**Enforcement:** a global `PreToolUse` hook (matcher `AskUserQuestion`) in `~/.claude/settings.json` hard-denies the popup and returns this rule as the reason — the prose alone proved too easy to forget. Because the deny is unconditional, the "use the popup for this one" exception above can't be honored in-turn; to get the popup, disable the hook via `/hooks` (or edit settings) first.

 ## No Reverse-Video Highlighting in Chat Output
 
 In conversational output to the user, do not use Markdown bold (`**...**`) or inline-code spans (backtick `` `...` ``). The user's terminal renders both as reverse video, which is hard to read on the display.
