chore: sync generated bundle after modularization

[ByBrawe]

Summary

Final cleanup after the V1 source modularization slices.

• regenerate the committed single-file stable src/index.js from the now-modular src/source/ tree;
• keep the final PR diff limited to the generated bundle only;
• remove the temporary same-repo bundle-sync workflow before merge;
• preserve package version 0.5.32 and all user-visible behavior.

The source modularization itself was already validated on the immediately preceding exact source head (a8256b7f58057b54483f3b6335c0bbaf620bf60f) by CI, Single-file Bundle Gate on Linux/Windows, and V2 Lifecycle Contract. This final bundle-only PR does not match the Bundle/V2 path filters (src/source/** / src/source/runtime/**), so only normal CI is expected to run on the cleaned exact head.

Verification

Exact cleaned head f0d9b7a6290cdf4bec70f59a3ec7983972bc7d61:

• final diff: only src/index.js;
• CI: success, including Linux/Windows tests, OpenCode 1.4.0/latest compatibility, and real OpenCode Loop hosts on Linux/Windows;
• temporary sync workflow removed from the branch;
• generated bundle was produced from the modular source by the temporary build step before that workflow was removed.

No runtime state schema, command behavior, or package-version change.
