feat: unwrap Provider namespace + improved automation script#22690
Merged
Conversation
…king
Convert `export namespace Provider { ... }` (1709 lines, 20+ AI SDK imports)
to flat named exports with `export * as Provider` barrel.
This is the highest-value conversion — Provider was the worst tree-shake
offender, forcing cli/error.ts to pull in all AI SDK packages just for
error type checks.
Also upgrades the unwrap-namespace script to automatically handle:
- Self-references (NsName.Export → Export)
- Import path rewrites across src/, test/, script/
- Sibling imports within the same directory
36 import rewrites + 1 sibling fix, all automatic.
251 provider tests pass, full typecheck clean.
