PR Review: build: Update swc_core to v63.1.0

This is a routine dependency bump updating swc_core from v61.0.1 to v63.1.0, along with all compatible swc crate versions. The changes are mechanical and well-structured.

Summary of Changes

• Cargo.toml (workspace): ~20 version bumps across swc crates
• Cargo.lock: Updated checksums and local package versions to match

Observations

Version gap (minor note)
The jump goes from v61.0.1 directly to v63.1.0, skipping v62.x. This is fine if v62.x was released and then quickly superseded, but worth confirming no intermediate compatibility shim is needed for consumers upgrading from v61.

Notable version jumps in dependencies

• swc_ecma_minifier: 49.0.0 → 51.1.0 (two major versions in one step)
• swc_ecma_transforms_base: 40.0.0 → 41.0.1
• swc_ecma_utils: 28.0.0 → 29.1.0
• swc_ecma_ast: 22.0.0 → 23.0.0

These jumps are expected for a core update but suggest non-trivial internal changes. If any downstream plugin behavior is affected by AST or transform changes, tests should catch it.

Changeset bot warning
The changeset bot flagged that no changeset was added. If these plugins are published to crates.io as part of this update, a changeset may be needed so consumers can detect the new compatibility range. If this is an internal/build-only update and publishing is handled separately, this is fine.

Socket Security: Passed — no supply chain concerns flagged.

Code Quality

The changes are correct and consistent: every version in Cargo.toml has a corresponding checksum update in Cargo.lock. No stale entries or mismatched versions detected.

CI Status

CI checks were still pending at review time. The review should not be merged until:

• Test - ubuntu-latest and Test - windows-latest pass
• Integration Test (ubuntu-latest) and Integration Test (macos-latest) pass
• Check (swc_ast_unknown) passes

Verdict

LGTM pending CI. This is a clean, automated dependency update. No logic changes, no security concerns, and the structure of the diff (only Cargo.toml + Cargo.lock) is exactly what's expected for a pure dependency bump.

Fixed CI

• Check CI status to identify failures
• Investigate root cause
• Fix packages/feature-flags/Cargo.toml version reference
• Commit and push changes

Root cause: The major version bump (from the previous commit) updated crates/swc_feature_flags to 3.0.0, but packages/feature-flags/Cargo.toml still had a hard-coded version = "2.0.0" in its path dependency. Cargo requires that the version in path dependencies matches the actual crate version.

Fix: Updated swc_feature_flags version in packages/feature-flags/Cargo.toml from 2.0.0 → 3.0.0.
