fix: keep drag transform snapshots current

[pupuking723]

Fixes #2055

Summary

• Compute the next drag transform for dragmove event snapshots from the pending move coordinates.
• Refresh the cached operation transform after the move is committed, so later snapshots such as dragend do not depend on the Feedback plugin reading dragOperation.transform.
• Add a manager-level regression test for modified transforms when no feedback plugin is involved.
• Add a patch changeset for @dnd-kit/abstract.

Testing

• npx bun@1.3.11 test packages/abstract/tests/manager-modifiers.test.ts
• npx bun@1.3.11 run --cwd packages/abstract build
• git diff --check

Note: I also tried running ESLint directly on the changed files, but it failed before linting with an ESLint/Ajv initialization error (Cannot set properties of undefined (setting 'defaultMeta')).
