feat(manager/ant): add property resolution and .properties file support

[RahulGautamSingh]

Changes

• Resolve same-file <property name="..." value="..." /> references in version attributes
• Load external .properties files via <property file="..." />
• Implement first-definition-wins semantics matching Ant's property immutability
• Detect and skip circular and unresolvable property references
• Support chained property resolution (property values referencing other properties)
• Add updateDependency function for both XML <property> value attributes and .properties file values
• Track sharedVariableName and redirect fileReplacePosition to the property source file
• Group dependencies by their property source file, with editFile set for cross-file updates

Why updateDependency instead of auto-replace

The default auto-replace function calls extractPackageFile (single-file extraction without property resolution) to confirm the update succeeded. For property-backed dependencies, this always fails because extractPackageFile sees the raw ${placeholder} instead of the resolved value.

Context
