WorthIR v1.1.1

WorthIR v1.1.1 aligns the tagged source with the downloadable source archives and installed wheel.

English source and release tag: 8817ead

Simplified Chinese counterpart: c805bfe

Changes:

• preserves LF line endings and Unix execution permissions for the worthir launcher;
• tests the built wheel from outside the repository on CI;
• uses worthir in installed-mode guidance from demo-custom, build-custom, build-trec, and init;
• keeps generated task directories free of packaging cache files.

The v1.1.0 release remains available unchanged.
