* Lenient semver comparison for the marketplace's `minAppVersion` gate.

|
|
* Parses "major.minor.patch" (any segment may be missing — treated as 0)
|
|
* and ignores pre-release / build metadata. Returns negative, zero or
|
|
* positive in the same shape as Array.prototype.sort comparators.
|
|
*
|
|
* We intentionally do NOT pull in a full semver dependency: plugins
|
|
* declare minimum app versions as simple "X.Y.Z" strings and we only
|
|
* need a >= check.
