Fixes from the latest Linux retest (v3.1.6, 614dbab).

Fixed

• Seamless loop and Spotify Canvas export failed with ffmpeg exit code 234 ... xfade ... current rate of 1/0 is invalid. After trim and setpts the two branches had no frame rate and xfade needs one. loopPlan now adds fps=<fps> after each setpts=PTS-STARTPTS. Checked with a real ffmpeg 7.1 run through buildArgs (320x180, 2 s, 30 fps): before the change exit 234; after it exit 0, 60 frames, yuv420p, 30 fps, 2.000 s.
• Floor Reflection / Reflection Length did not appear until the panel re-rendered. The Placement segment now has rebuild: true, and Reflection Length no longer waits for the reflection slider to be above 0 (sliders do not rebuild the panel).
• Blend "Screen" showed "Display" in the English UI. It now has its own i18n key (the Turkish text is unchanged); the display section keeps "Display".
• Audio bridge window stayed on "Starting" when no pairing secret was set (bridge-only mode reported no problem because the saved config has send: false). It now shows "Secret missing".
• Studio list: a cut-off preset name shows in full as a tooltip.

Layout import (#4), by design, no code change: a layout file with a text element adds a second visualizer-type layer, because text is a sub-type of the visualizer layer. A fresh scene ends up with [background, visualizer(bars), visualizer(text)]; importing the same file again updates those layers (updated 2, added 0). Covered by a test.

Skipped: sv_list_modes labels stay Turkish. The mode catalog labels live in the renderer sources and the English dictionary is not available in the main process, so it is not a cheap change; the ids are language independent.

Tests: npm test 3582 tests, 0 fail (3 skipped on this machine, environment dependent). New tests cover the loop graph, the Screen label, the Placement rebuild, the layout import and the bridge status. README.md, README.tr.md and ROADMAP.md counts set to 3582; CHANGELOG entry added.

CaYaDraft — pull request

Summary
This pull request fixes a seamless loop and Spotify Canvas export failure caused by missing frame rate information after trim and setpts operations, resolving an ffmpeg exit code 234 error. It also addresses four UI issues: the Floor Reflection panel now rebuilds immediately upon slider changes, the Blend "Screen" option correctly displays as "Screen" instead of "Display", the Audio bridge window shows "Secret missing" when no pairing secret is set, and cut-off preset names display full tooltips on hover.
