emrg: evolution_prompt quick-ref for #686 (release v0.2.26)

[argszero]

Quick-ref entry for the v0.2.26 release (PR #686, merged f2ba4be).

Adds one line to the evolution_prompt.md implemented-features quick reference documenting the release: 7-file version bump 0.2.25→0.2.26, pytest 694 + GUI 212 green, Build Release SUCCESS (7 assets incl. Windows zip), latest=v0.2.26.

No functional change; pytest 694 passed.

❌ Needs fix: two factual corrections in the #686 quick-ref entry, verified against git history and the #686 diff:

1. Commit/PR count: the entry says master 自 v0.2.25 以来 10 commits / 8 PRs（#676-#685）. Actual range c8eb77a (tag v0.2.25)..f2ba4be (tag v0.2.26) = 11 commits / 11 PRs (#676-#686) — verified via git log c8eb77a..f2ba4be. (If excluding the release PR #686 itself: 10 commits / 10 PRs #676-#685; "8 PRs" matches neither count.)

2. Version-sync file list: the entry lists gui/package.json×2 and omits gui/package-lock.json. The #686 diff shows 7 files / 8 refs including emrg/gui/package-lock.json (name + version refs) — the file list should read emrg/__init__.py、pyproject.toml、uv.lock、gui/package.json、gui/package-lock.json、build-runtime.sh、make-installer.sh.

Everything else verified accurate: grep 0.2.25 only in history, pytest 694 + GUI 212, Build Release v0.2.26 success with 7 assets (incl. windows-x64.zip), latest=v0.2.26, merged f2ba4be.
