continuous
fix(memory): keep the frame pool from regrowing after every structura…

🚀 New Features

• Console toolbar: New toolbar with Clear, Find, Collapse, Pause/Resume, Text/Hex display mode, and Settings controls. Pause freezes the display only — data keeps flowing to the raw buffer and exports.
• Console search: Press Ctrl+F (Cmd+F on macOS) to search the console, with match count, wrap-around navigation, case toggle, and highlight-all (#344).
• Console duplicate collapsing: Consecutive identical lines merge into a single entry with a live repeat-count badge, devtools style. Display-only — copy and export keep the full stream (#285).
• Console scrollback: Configurable scrollback depth (100 to 100,000 lines) and an interactive scrollbar: drag to scrub, click to page, drag to the bottom to re-engage autoscroll.
• FFT window functions: Pick from 15 window functions per dataset (Rectangular to Parzen, default Blackman-Harris), applied to both the FFT plot and the waterfall.
• 3D plot auto-scale: New auto-scale toggle that tracks the data extent, plus reusable render buffers for smoother drawing.
• USB endpoint selection: Endpoints are now visible and selectable before connecting, interrupt endpoints stream alongside bulk, isochronous alt-settings are activated automatically, and your selection survives hot-plug rescans.
• Project editor navigation: Jump to datasets directly from the group view, with per-dataset icons on the navigation rows.
• Faster GPS maps: Map tiles now share one downloader with a 256 MB on-disk cache, transfer timeouts, and automatic retries.
• Signed Linux packages: AppImage, .deb, and .rpm packages are GPG-signed, with the public signing key attached to every release.
• API server: project.snapshot gains section selection and paging, meta.listCommands gains a compact names-only mode and no longer lists duplicates, and the MDF4 player commands regained their parameter hints.

🐛 Bug Fixes

• Plots: Area fills and stem baselines clamp at the zero line, so near-zero or all-negative signals no longer fill the wrong half of the plot; flat-zero signals hide the fill entirely, and an all-non-finite sample scan can no longer blow up the axis range.
• Windows & dialogs: Window shadows are now drawn by the OS/compositor instead of being painted in-app, fixing dialog sizing, screen-edge snapping, resize handles, and popup clipping.
• Bluetooth LE: Selecting the "Select Device" placeholder clears the previous selection, so the connect button can no longer link to a stale device.
• Waterfall: Persisted widget settings restore reliably during widget creation.
• Project editor: The Hide/Show context-menu label now tracks the item's real state on group folders and output widgets.
• Microsoft Store: The taskbar icon no longer renders on a blue accent-color plate (unplated icon assets and resources.pri are now shipped).
• Console: Empty lines no longer receive a dangling timestamp prefix.
• Scripting: The Lua os table in MQTT publisher scripts is restricted to side-effect-free time functions.
• Licensing: Fixed late/offline activation races, and GPL builds no longer compile any license-guard code paths.
• Stability: Two audit sweeps fixed ~160 defects across the API server, IO drivers (UART/USB/Audio), exporters (MDF4/CSV/console), MQTT publisher, and dashboard widgets; batch deletes now take a single recovery snapshot instead of one per item.

📚 Documentation

• New help pages: Windows Installation (MSI, portable ZIP, Microsoft Store) and Linux Installation (per-distribution steps and GPG signature verification).
• The frame parser reference now documents the editor's parse() validation probe and why length guards are required.
