Fix stacked Ask AI Enter replays and light-mode code contrast

[yashovardhan]

Summary

• The Ask AI stale-question guard started a new catch-up poll on every intercepted Enter and never canceled the previous one, so a second Enter before the option caught up could replay submit more than once. Cleanup only removed the keydown listener, so a late interval could still fire after the workaround was torn down. The guard now keeps a single poll, replaces it on a later Enter, and clears it on abandon, catch-up, timeout, and cleanup.
• Ask AI answers render fenced code as <pre><code class="language-js">, which the site's Prism theme claims with !important and paints in the light gray it uses on the dark code blocks of doc pages. DocSearch backs its code blocks with the modal surface instead, so in light mode that gray landed on near-white (#c8ceda on #f5f5fa, roughly 1.3:1). Ask AI code blocks now take their color from --docsearch-text-color.

Measured after the change: light modal #36395a on #f5f5fa (~9:1), dark modal #e3e3e3 on #36395a. The sidepanel was already covered by existing light and dark overrides and is unchanged.

Test plan

• Open search, highlight Ask AI while the option still shows a previous query, press Enter twice quickly, and confirm the conversation is submitted once with the typed query.
• Repeat with a single Enter and confirm catch-up still waits, then submits.
• Type again or close the modal while a wait is in flight and confirm no stray submit.
• Navigate away (effect cleanup) while a wait is in flight and confirm no late replay.
• Ask a question that returns a code block in light mode and confirm the code is legible in both the search modal and the sidepanel.
• Repeat in dark mode and confirm no regression.

Note

Low Risk
Client-side DocSearch keyboard workaround and scoped CSS override; no auth, API, or data-path changes.

Overview
Fixes double Ask AI submits when Enter is pressed before the highlighted option catches up to the search input. The stale-question guard now keeps at most one catch-up poll: each new Enter clears any in-flight wait, and teardown clears the interval so a replay cannot fire after navigation or after the user already submitted.

Separately, Ask AI markdown code blocks in DocSearch (modal and sidepanel) now use --docsearch-text-color instead of the site Prism theme’s light gray, which was nearly illegible on the light modal surface.
