Mimic v0.2.4 — Public Beta

Mimic v0.2.4

Changes since v0.2.3:

• Keep internal snapshot preparation contexts and pages out of browser automation discovery. Creating and closing application contexts now produces a stable public context list while the runtime prepares its cache.
• Wait for internal snapshot preparation and page cleanup during shutdown, preventing overlapping preparation from retaining resources or using a closed realm.
• Complete accepted page, context and browser close commands even when the automation client immediately disconnects, while still cancelling ordinary session work on disconnect.
• Add PNG screenshots through the standard CDP Page.captureScreenshot command. They reflect the current DOM after script interactions, but visual accuracy is not guaranteed; the separate renderer does not represent Mimic's script-visible layout. See approximate screenshots for the supported scope.
• Improve approximate painting of SVG, CSS grid sidebars, styled controls and literal ::before/::after text. The screenshot renderer now uses a maintained, static-only go-webengine fork without its browser, JavaScript or module-bundling packages.
• Preserve resource timing order when separate fetch starts resolve to the same exposed startTime.

Mimic remains a public beta for Windows and Linux amd64. Browser automation support follows the documented CDP scope. Full source changes: v0.2.3...v0.2.4.
