gui_toolkit 0.102.0

Added

• toolbox package (tk_toolbox, docs/toolbox.md): what the tools of a project share. run (the output shown or appended to a log; a working directory, an environment, a time limit, echo), capture (the standard output and the exit code, the standard error shown on failure), env_with, exit_code and succeeded (a Windows exit code read as the program's signed 32-bit code), sha256_hex and sha256_file, download_pinned (curl with retries, GitHub's API when a release download fails, a file whose SHA-256 is wrong removed), download_through_api, release_asset_id and system_program. tools/tk uses it; its own copies of these procedures are gone.
• paint package (tk_paint, docs/paint.md): a vector rasterizer on the CPU for pictures made ahead of time, pure Odin and deterministic: an RGBA canvas with a transform, paths (lines, quadratic and cubic Béziers, arcs, rounded rectangles, ellipses, polygons), fill (non-zero, even-odd) and stroke / widen (width, miter, bevel and round joins, flat, square and round caps) with antialiasing, solid colours and linear / radial gradients that pad or repeat, set_clip, draw_canvas / resize (cubic for downscaling, nearest for magnifying), png_encode / png_decode, ico_encode with PNG or DIB entries (dib_encode). tk make_logo and tk make_icon draw with it on Windows and Linux; GDI+ and tools/tk/gdiplus_windows.odin are gone.
• desktop package (tk_desktop, docs/desktop.md): the integration of a program with the user's desktop (Start menu and desktop shortcuts, the PATH with a console launcher, the freedesktop.org entry and icons, a link in ~/.local/bin, and for a browser its registration and URL schemes), its watcher, its command line, and the installed copy (manifest, Settings > Apps record, uninstall, NixOS runtime). Every name and mark is a field of the program's Identity; every place is an injectable root. Moved from Wren and made generic. process package (tk_process, docs/process.md): command_line_args (UTF-8 on Windows), console_write / console_error (a Windows program with a window writes to its parent's console), executable_path, parent_dir.
• tk site_docs: the documents of docs/ as a "Docs" section of the website, with its own Markdown to HTML converter (tools/tk/site_docs.odin). The Pages workflow runs it.
• cdp and site packages (src/cdp, src/site): a client of the DevTools protocol for tools (a window or a browser, input, waits, pictures, screencasts, scripts, timelines compared with another run) and the steps of a project website (CHANGELOG.md to a changelog page, news and classic pages, what a page says when shared, Markdown to HTML, the pages checked in a real browser), generic: opencode native uses both. docs/cdp.md, docs/site.md.

Changed

• The Node tools are tk commands: tk cdp (was tools/cdp.mjs), tk screenshots, tk theme_shots, tk timeline_test (was tests/e2e/timeline.mjs), tk doc_check (same flags: --root, --extra), tk site_build, site_changelog, site_meta, site_card, site_check. The CI and the Pages workflow run only Odin; Node is no longer needed.

Fixed

• tk site_check checks the site as it is published (the Docs pages and the 404 too) and waits for what each step leads to instead of fixed delays (opencode native's check, now shared): the old check hung when the viewer did not open. tk theme_shots reads the palettes from src/ui/theme_default.odin (tools/theme_shots.mjs still read ui/, gone since the packages moved to src/).
