Create the app icon and finalize versioning

App identity for both editions: the three-lane glyph
(rectangle.split.3x1.fill) over a gentle gradient - teal for base
Lanework, dark graphite for Lanework Pro - rendered as 1024 masters and
packaged down the full macOS ladder into each target's own iconset,
replacing the borrowed pathfinder icon.

The About window arrives via IndieAbout (0.2.x): icon, copyright,
version/build/date read from the Info.plist that update_build_info.sh
already stamps on every build (CFBundleVersion 160 = git commit count,
BuildDate, BuildHash - verified in the built product), the version line
opening the bundled CHANGELOG.md, and the new ISC LICENSE.md one
document link away. Both files are authored to the Apple
inline-Markdown subset (no # headings, single-line paragraphs) and
bundle into both editions.

CHANGELOG.md replaces its placeholder with the real 2.0 first-release
notes - one sentence per user-facing feature.

The About box is also an edition seam: base's EditionAbout carries the
one-line Pro signpost 12-editions.md allots ("Lanework Pro adds
git-backed board history and sync."), and the Pro target compiles its
own signpost-less twin instead of that file - the no-#if file-level
doctrine applied to a string. README gains the identity bullet.

1649 green on both schemes; verify-editions.sh 26/26.
