Arkos IDE 0.3.1

• Settings steps the window's preset; review fixes for 8a
• README: the menu, About, Settings, Timo Purple
• Settings shows the bare ready version, follows the theme, writes untouched preset values as they are, resolves the preset as the Root does, and lists a missing theme
• About refreshes when asked again; the daemon row drops the binary name; the themes row makes its folder
• The Settings window: appearance, themes with import, text, startup, updates
• One rebind for both config paths; a missing launch state is a wiring bug; the fingerprint precedes the load
• The About window: build, update and install details, and the attribution
• Theme docs name the surfaces the test checks; the theme dispatch keeps its own comment; the import test holds its temp dir
• One menu, two actions, a window registry, and the quit rules for About and Settings
• build_date's dead-code allow is plain; a huge install marker counts as missing
• Timo Purple ships; the theme schema is documented; arkos theme list and validate
• Config edits keep comments; an install marker; the build date
• frame.py: the hero's captions a quarter smaller
• frame.py: the hero's captions back on the stills, the backs showing enough to carry them
• frame.py: the hero's captions in a band under the stills, sized for the README's width
• frame.py: the hero's captions at twice the size
• The README's pictures: the composed hero and the three scenes
• arkos-shoot: ends what a session left running in the demo (a smoke-test server outlived its shell)
• windows.swift: floating windows are listed too (the shoot's window is one now)
• The shoot's window floats above the others: a covered window is not drawn
• arkos-shoot: the demo may search the web; the multi tasker's shot keys on the subagents' fan-out
• frame.py: the hero's captions sit on each still's bottom edge, the backs show more
• arkos-shoot: three scenes and a composed hero, run as an app of its own
• arkos-shoot: the bundle is signed with the Developer ID, not a self-signed one
• The README's picture: a real session, from scripts/shoot.sh
• Plan 8a amended after review: binding order, a window registry, close rules, whole preset writes, Timo Purple values
• Releases signed with a Developer ID and notarized, from the workflow or a Mac
• Plan: the menubar, About, Settings and Timo Purple (milestone 8a); spec marked approved
• identity.sh: macOS's own openssl, whose PKCS12 security import can read
• arkos-shoot: a signing identity so the Accessibility grant survives rebuilds
• Spec: the menubar, About, Settings and the Timo Purple theme (milestone 8a)
