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.

+
+### Tuned — Wink probability lowered from 30% to 5%
+The wink Easter-egg added in v0.1.1 fired at 30% per page render
+when Buddy's mood was ≥ 75. Default mood is 80, so most admin
+visits hit the gate and ~30% of those flipped to wink. Stacked
+across the main admin page + dashboard widget visible on the same
+screen, Buddy ended up looking like he had one eye closed all the
+time — "stuck" rather than "playful".
+
+Dropped to 5%. Same wink visuals when it fires; just rare enough
+to feel magical instead of constant. Refresh ~20 times when mood
+is high and you'll catch one.
+
+### Changed
+- **`inc/state.php`**: `buddy_mood_label()` probability gate
+  `mt_rand( 1, 100 ) <= 30` changed to `<= 5`. Docstring updated
+  to reflect new ~5% rate.
+- **Plugin version bumped**: header + `BUDDY_VERSION` constant
+  0.1.1 → 0.1.2.
+- **About page** version-history card leads with v0.1.2; v0.1.1
+  demoted.
+
+### Not changed
+- Wink visuals (`inc/sprite.php`) — same closed-eye arc, smirk,
+  rosy cheeks when it fires. Just rarer.
+- All other behavior identical to v0.1.1.
