chore: ignore workflow swc caches

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed

Backport PR opened against stable: #2650. (backport job run)

[NathanColosimo]

Summary

• Add local /.swc ignores for workflow-building packages and workbenches.
• Keeps generated SWC/plugin cache directories out of dirty worktrees when builds run from each project directory.

yes this duplicates .swc, there are more complex fixes, but it has no effect and means no one needs to look at it every time it is regenerated multiple times per day

Testing

• pnpm build
• pnpm --filter './workbench/*' build
• pnpm changeset status --since=main → no changeset needed
