HTML Challenge UX polish, UI scale, preview hardening#43

Release v0.7.4
Frontend - Drop fixed 1280x720 preview stage; iframe fills frame-shell directly so pages reflow at the actual rendered viewport like a resized browser. - Inject in-iframe scripts: localStorage/sessionStorage shim (so sandboxed pages that read storage on init don't abort), CSS reset with zero-specificity :where() rules, scrollbar styling, body/html bg detector that posts the computed colour back so the frame shell can match the page theme, and a content-bounds zoom-to-fit helper for pages with overflow:hidden bodies and oversized canvases. - Add UI scale (85/90/95/100%) via CSS `zoom` on `.app-shell`, with matching layout-box oversize so the app keeps filling the viewport at scale<1 and a `zoom: 1/scale` cancellation on the preview shell so iframes stay pixel-aligned. - Slot card: name + meta badges share a single row with ellipsis on long names, Thinking becomes a select that lives in the same row as Temp / Seed / Randomize, all controls share a 110x32 footprint. - Stream pane: fixed-height clamp(280px, 38vh, 520px) so streaming output scrolls inside its own box; auto-scrolls when at tail. - Setup panel: dropped duplicate "HTML Challenge" header + folder-path subtitle, moved Run / Cancel / Use Prompt and New Challenge + history search into a single top action row, search input wider. - History dropdown: per-row trash icon (fades in on hover) replaces standalone Delete button. Confirms via window.confirm. - Per-slot Change Model button on every manifested slot. Confirming the picker auto-retries the slot with an explicit override payload so manifest filename + metadata + rendered HTML stay consistent. - Random seed per slot (`int32` range), Randomize button on each card. Backend - Apply `mx.random.seed` before DFLASH/DDTree branches so seeds aren't silently dropped under speculative decoding. - Soft-delete challenges into a sibling `.trash/` directory instead of `shutil.rmtree`; restorable from disk, no third-party trash dep. - After a slot rerun, unlink the previous filename when the new model slug differs (path-traversal guarded) so folders don't accumulate orphan HTML files keyed to old model names. Tests - Updated `test_html_challenge_accepts_per_model_thinking_settings` for the slimmed payload (kept `seed`, dropped `topP` / `diversityStyle` / `diversityMode` which were UI-only and removed).
