## Summary
- Fixes `bun pm pack` not respecting changes to `package.json` made by
prepack/prepare scripts
- Tracks whether lifecycle scripts (prepublishOnly, prepack, prepare)
ran
- If scripts ran, invalidates the cached package.json and re-reads from
disk before creating the tarball
Closes#24314
## Test plan
- Added regression test `test/regression/issue/24314.test.ts` that
verifies package.json modifications from prepack/prepare scripts are
included in the tarball
- All existing pack tests pass (69 tests)
