Set the 0.2.0 release date to 2026-10-18 and remove the pre-publication installation notice from both READMEs. The package version remains 0.2.0; runtime code and dependencies are unchanged.

Validation:

• All 10 CI checks passed on this commit.
• Built the source distribution and then the wheel from that archive; strict Twine metadata checks passed for both.
• Installed the wheel in a fresh environment outside the checkout and verified the package version, both CLI entry points, an exception save/load round trip, shared references, and report output to stdout.
• Checked package contents against the source and confirmed local review notes and caches are excluded. git diff --check passed.
