chore: release v0.1.2 — wink tuning entry

Documents the wink-probability tune-down (f661eab) as a proper
patch release. No code behaviour change in this commit — purely
version metadata, changelog, and user-facing about-page history.

CHANGES
- buddy.php: Version header + BUDDY_VERSION constant 0.1.1 → 0.1.2
- CHANGELOG.md: new [0.1.2] entry above [0.1.1], explains the
  tuning rationale + what's intentionally unchanged (wink visuals,
  trigger threshold mood >= 75)
- inc/about.php: version-history card leads with v0.1.2 (latest
  badge), v0.1.1 demoted to second slot

Why a patch release: the wink fires far less often now than it
did in v0.1.1. From a user's point of view that IS a behaviour
change worth a version. Following SemVer: PATCH bump because the
public API and feature set are unchanged; only the tuning of an
existing behaviour was adjusted.
