ArtifactFS 1.0.0-rc.3

Release candidate for ArtifactFS 1.0.

This supersedes 1.0.0-rc.2. The rc.2 tag was cut before the PR branch's required Go 1.25 modernize fix landed; rc.3 points at the merged, build-passing main commit.

Changes since 1.0.0-rc.1:

• Update Go dependencies, including modernc.org/sqlite to v1.53.0, github.com/jacobsa/fuse to the 2026-06-03 revision, and github.com/urfave/cli to v1.22.17.
• Update the Cloudflare Sandbox SDK example dependencies, including @cloudflare/sandbox to 0.12.2, wrangler to 4.105.0, Workers types to 4.20260626.1, TypeScript to 6.0.3, and Node types to 26.0.1.
• Include the async hydration performance fixes and overlay/stat-cache fixes that landed after rc.1.
• Apply the Go 1.25 modernize updates required by CI for hydrator tests and benchmarks.

Potential breaking changes:

• ArtifactFS now requires Go 1.25+ to build. The updated modernc.org/sqlite stack declares Go 1.25, and the README has been updated to match.
• The sandbox example now tracks newer pre-1.0 @cloudflare/sandbox packages. Pre-1.0 minor releases can include API changes, so downstream examples copied from this package should re-run type checks.
• The example type environment moved to TypeScript 6 and @types/node 26. That can expose stricter type errors in copied or extended example code.

Verification:

• PR #25 Build & Test passed on the merged branch content.
• PR #25 CodeQL and Semgrep checks passed.
• Local verification before merge: go build ./cmd/artifact-fs, go vet ./..., go test ./..., and npm run typecheck in examples/cloudflare-sandbox-sdk.
