* docs(readme): four-surface hero grid with per-surface install shortcuts
Replace the single TUI screenshot and the scattered optimize, compare and
old menubar shots with one 2x2 grid under the badges: Desktop, Web,
Terminal, and macOS Menubar, each with its one-line way in (direct
download badges for the desktop builds, npx codeburn web, npx codeburn,
codeburn menubar). New screenshots downscaled to 1600px so the README
stays light.
* docs(readme): star and sponsor ask up top, consistency pass
Adds a one-line ask under the badges: star the repo if CodeBurn showed
you something the bill never did, sponsor to keep 36 integrations
honest. Caption line under the hero grid.
Consistency fixes from a full read: the sponsor section said 30
integrations while everything else says 36; dx is the Dioxus CLI, not a
package runner, so the install line now says pnpm dlx; the by-agent
command row was overstuffed for a table cell; Opus 4.6 in the signals
table aged into Opus 4.8; the License section ran MIT and the affiliation
note into one paragraph; two stray em dashes and a double blank line.
