redesign(ai): name-only Cloud model picker — drop the per-row debug detail

[ndemianc]

Why

A client just wants to pick "the latest shining Opus 5" — but every row in the Cloud model picker carried three technical fields: the raw id (anthropic/claude-opus-5), the context size, and a N× credits · NK ctx · ≈N turns left second line. Useful for debugging, noise for choosing. The two-line rows also made the list dense and the model name small.

After

Each model is a single, name-forward line — like the Cursor / Claude Code pickers the request pointed at.

🔒 Sonnet 5  anthropic/claude-sonnet-5          🔒 Sonnet 5   coming soon
   4× credits · 200K ctx · coming soon

The plan + remaining credits stay in the placeholder (LevelCode Cloud model · Plan: Max · $52.77 credits left), so the one number that actually matters isn't lost — only the per-row debug detail is gone.

What changed

• Dropped per-model description = id, the ctx / multiplier / turns detail line, and fmtTurns (now unused).
• matchOnDescription: false — typing filters by the model name only (no hidden id matching), so "opus" narrows to the Opus rows.
• Staged rows keep the one meaningful hint, coming soon, and carry _name — the "coming soon" toast used to read the model name out of description, which is now literally the string "coming soon".
• Net −13 lines.

On "increase the font size"

It's a native VS Code QuickPick, so its font follows the app's UI font and can't be set per-picker by the extension (same for the command palette). The single-line, name-forward rows are what deliver the big/clean read. A literally larger font would mean replacing the native picker with a custom webview (re-implementing filtering + keyboard nav + theming) — happy to do that as a separate change if the redesign here isn't enough.

Scope

Cloud picker only (pickCloudModel). The BYOK picker (pickModel) has the same id+detail pattern but a different audience — power users who often want the exact model id — so I left it. Say the word and I'll mirror this there too.

Pull request overview

This PR simplifies the LevelCode Cloud (gateway) model QuickPick UI to be name-forward, removing per-row debug metadata (model id/context/multiplier/≈turns) while keeping plan + remaining credits in the picker placeholder.

Changes:

• Removed the per-model secondary detail line and the now-unused fmtTurns helper; Cloud model rows are now label-only.
• Updated staged (“🔒”) rows to show a visible coming soon description and preserved the model name for the info toast via _name.
• Switched Cloud picker filtering to matchOnDescription: false so searching matches only what’s visible in the row label (the model name).
