chore: release v0.8.45

[miga-heygen]

Release v0.8.45. Generated by npm run release:prepare 0.8.45 off main at 77a45f6, with the release notes and changelog entry written by hand.

18 files: 17 version manifests, releases/v0.8.45.md, and the prepended docs/changelog.mdx entry. Zero source changes.

Replaces #4024, whose head predated the two motion blur fixes that must be in this release (#4025 and #4026).

What the notes say, and why

• Motion blur ships as two separate mechanisms for two different jobs, described as alternatives rather than layers. Applying both blurs the same motion twice.
• The catalog component (fix(registry): make motion-blur match After Effects shutter-based blur #4008) keeps its After Effects claim, because matching After Effects is its purpose and the numbers are measured: 24.19 dB to 32.51 dB mean over 72 frames against a real export.
• The engine path is described by what it does, the shutter integral over the whole composition, with no After Effects comparison attached to it. It is a different picture on purpose.
• Cost is stated: one capture per sample, and roughly 600 ms of blend per 1080p frame at 16 samples on top of the 16 captures.
• A "Known limits" section carries the video-motion limit, the refused capture modes and layered route, the PNG-only capture, and the wide uncentered shutter overshoot, which is marked unproven rather than described as safe.

Credit

The static-window dedup guard (#4025) and the explicit unsupported-mode error (#4026) are designs from #4013 by Dante-dan, credited in the notes.

Reviewed at d0ab83f. Own-account, all required checks green, zero source changes.

18 files: 17 version manifests 0.8.44 to 0.8.45 (grepped, all 17 confirmed), releases/v0.8.45.md, docs/changelog.mdx prepend. First-parent log from base 77a45f6 confirms exactly the PRs the changelog cites: #4026, #4017, #4025, #4020, #4022, #4008, #4014, #4019, all real commits, all hashes verified to exist. Content matches Home's brief: two motion blur mechanisms presented as alternatives with a cost/tradeoff section, catalog component keeps the AE comparison with measured dB (24.19 to 32.51 avg, 17.07 to 27.57 worst), engine path has no AE comparison, 600ms/1080p-frame cost at 16 samples stated, known-limits section present, #4013/Dante-dan credited on both fixes.

Verdict: APPROVE
Reasoning: generated release content, zero source diff, every cited commit and number verified against the real log, not the PR body's word.

APPROVE at d0ab83f0 — v0.8.45 release PR verified as genuine no-source-diff

Reviewed at head d0ab83f01deefe7db4a84a8173590856de428e34, base 77a45f6080daedd12ab67a3d1c9d165b8ae003b3 (matches Miga's cited main SHA 77a45f60).

Load-bearing check: no code diff.

18 files, +97/-16, single commit d0ab83f0 (chore: release v0.8.45, authored by miguel-heygen). Every non-notes file is a pure version-string bump 0.8.44 → 0.8.45:

• 3 plugin manifests: .claude-plugin/plugin.json, .codex-plugin/plugin.json, .cursor-plugin/plugin.json — each +1/-1 (version line only)
• 13 package.json files (aws-lambda, cli, core, engine, gcp-cloud-run, lint, parsers, player, producer, sdk, shader-transitions, studio-server, studio) — each +1/-1
• 2 release-notes files: releases/v0.8.45.md (+40, new file) and docs/changelog.mdx (+41, append)

Verified programmatically: 16 lines of - "version": "0.8.44", paired with 16 of + "version": "0.8.45", — one pair per manifest, no additional non-version lines in any package.json or plugin.json (awk filter for ^[+-][^+-] excluding notes files + version-key returned empty). No engine/producer/cli source files touched. Zero code smuggled.

CI at this head: 58 SUCCESS + 6 SKIPPED + 1 pending. Zero FAILURE. Matches Miga's "58 checks green, 6 skipped, none failing."

Approvals so far: Miga COMMENTED at 02:54:22Z (gate-marks); miguel-heygen APPROVED at 02:57:01Z. Aggregate reviewDecision: APPROVED. My stamp adds an independent second eye on the release, verified against Miga's brief and the diff shape.

Given Miguel authorized the merge in Slack at 22:11 EDT and the diff is a genuine version-bumps-only release generated by the release script off main 77a45f60, this is safe to land v0.8.45.
