Attune Harness 1.0.1

Attune Harness 1.0.1 release notes

1.0.1 fixes documentation links on the PyPI project page. PyPI renders the
package README outside GitHub, so repository-relative links in 1.0.0 led to
404 pages. The README now links to release-specific GitHub documentation, and
the link check catches this class of error before a future release.

The runtime files, dependency pins and v1 compatibility contract are unchanged
from 1.0.0. Use an isolated environment:

pipx install 'attune-harness[all]==1.0.1'

See the 1.0.0 release notes for the stable scope,
qualification evidence and limits. This patch does not add model or platform
qualification. The originally planned fourteen days of candidate observation,
named non-programmer walkthrough, ordinary host and memory observations, and
migration trial remain unverified.
