What

Release v0.9.19: version bump, releases/v0.9.19.md, and the docs changelog. Merging publishes to npm.

Why

Ships the two changes on main since v0.9.18: a video that looks right in preview and renders blank when a set interrupts a running tween (#7283), and a cloud render that stopped when a project used a font with no file on this computer (#7287).

No visible change

Version bump and changelog only. Each change was captured in its own PR.

Test plan

• bun run release:prepare 0.9.19 passed on current main, and the release notes name both changes. The compare link names v0.9.18.
• The branch is one commit on top of current main, and the local tag was not pushed.
• CI on this PR, including the packed package size budgets.
• Desktop walked with this PR's packed packages in place of its pins.

Requesting changes at 67e1fdaa: the release notes no longer match what this PR would ship.

Blocker: main moved after this branch was cut. #7287 (b56e2c03, "fix(cli): a font missing from this computer no longer stops a cloud render, and is named") landed on main after 6abc62a1. This branch is 1 behind main. Merged as it is, v0.9.19 would publish #7287 to npm, but releases/v0.9.19.md and docs/changelog.mdx list only #7283, and the PR body still calls #7283 "the only change on main since v0.9.18". The CI run on this head also never built #7287.

Fix: rebase onto current main, re-run bun run release:prepare 0.9.19 so the notes cover both #7283 and #7287 (and add the CLI tag), then update the PR body. The alternative is to state on purpose that #7287 is held back, which this merge path can't do.

Verified at this head (no other issues):

• All 19 version fields go from 0.9.18 to 0.9.19, and no other version string changes.
• The release notes and changelog entry match #7283, and the compare link names v0.9.18.
• All 11 Actions workflows on 67e1fdaa succeeded, including regression, Windows render, and preview-regression.
• The "fails without the fix" rule is met where the fix lives: #7283's body names the test "lands every frame where preview does when one worker renders in order" (expects [30, 1], gets [30, 0] without the fix). This PR is a version bump and doesn't need its own line.

Not blocking: The "Desktop walked with packed packages" item is still unchecked. Also, the fix only covers a set that interrupts a tween still running on the same property, so it isn't every local export.

Approving at 767d7d18. The blocker from my last review is fixed.

• The branch is one commit on top of current main (b56e2c03): 1 ahead, 0 behind.
• v0.9.18...main holds exactly #7283 and #7287. releases/v0.9.19.md and docs/changelog.mdx name both, with matching commit links. The changelog adds the CLI tag, and the compare link names v0.9.18.
• All 19 version fields go from 0.9.18 to 0.9.19, and nothing else in the diff changes.
• CI on this head passed: CI, regression, Windows render verification, preview-regression, PR captures, Docs, CodeQL, Lambda arm64 image, and both player perf runs. The cancelled runs were older duplicates on the same SHA, and later runs of the same workflows passed.
• The "fails without the fix" rule is met where the fixes live (#7283 and #7287). This PR is a version bump.

Not blocking: "Desktop walked with packed packages" is still unchecked in the test plan.
