v1.9.0-rc.3

Changes since v1.9.0-rc.2

• fix(notes): keep the note stylesheet in the production bundle
• feat(editor): turn on roundness, shadow and motion blur by default
• fix(cursor): make the Windows cursor sampler DPI-aware
• fix(hud): stop being born click-through, wait for the renderer to ask
• test(hud): pin that click-through is asked for, never born with
• docs(hud): replace the guessed exposure window with a measured one
• fix(agent): stop cutting the transcript at the 800th word
• docs(agent): the transcript tool no longer caps, so stop saying it does
• fix(ci): scope RC release notes to the previous RC
• feat(agent): add addTrims and addZooms, so a cut stops costing a round trip
• fix(agent): let a malformed batch entry fall alone, like every other one
• fix(media): watch the background path refresh instead of firing it into the void
• test(media): inject the failed registry write instead of chmod-ing the temp dir
• perf(test): run Vitest in node, and jsdom only where a DOM is needed
• docs(agents): run the tests you touched, not the whole suite each step
• fix(ci-scripts): clear the thread-validation timeout when fetch rejects
• fix(renderer): handle the detached promises that can actually reject
