Release v4.118.0

Added

• Added a screens release acceptance matrix to the Screenplay documentation. It maps each criterion of the screens-release issues to merged source, released versions and executed proof, and lists the browser runtime blockers that remain open. See Screens release acceptance. (part of #168) (part of #173)
• Added run-public-acceptance.sh, which runs the browser, MCP transcript and Studio acceptance harnesses with one command against the installed CLI and the Stage image that CLI defaults to. It fails when the CLI or Stage version differs from the expected one. (part of #173)

Changed

• The browser acceptance harness now runs the CLI's default Stage image instead of a pinned 4.49.2, records the CLI and Stage versions it actually ran, and removes its Stage container afterward. (part of #173)
• The browser acceptance harness reaches the work item list through the authored navigation before checking native create, finds a renamed row by its current title, and matches field labels such as "Comment Id". The full native create, rename and add-comment flow now runs end to end. A --self-test mode checks these helpers, and run-public-acceptance.sh runs it first. (part of #173)
• The canonical corpus now pins the AddComment identifier expectation to the authored model: commentId is a client-supplied, non-generated identifier, so a native form must collect it. (part of #168)
