Release 0.1.1

[nimbrel]

Version 0.1.1 in Cargo, pyproject and __version__, and the CHANGELOG's Unreleased section dated.

0.1.1 collects #1–#5:

• TSan attribution: a mutator refilling another library's buffer is a harness race; bare debug-info file names are no longer taken for crate files; races outside the extension are located at the plain access; threads and PyO3 frames are named.
• stress locates panics per thread and names panics inside dependencies.
• ci runs the tests the project configures, overrides strip, installs [build-system].requires, keeps raw logs per run, catches sessions that stop early, and notes when a module re-enables the GIL.
• Default suppressions for oneshot, crossbeam-epoch 0.9.18 and older, and glibc thread-local teardown.
• The TSan finding key keeps each access's line, so races under one inlined name are no longer merged.
