chore(perf): realign version to 9.0.0 to match .NET/MAUI versioning

Change version from 1.0.0 to 9.0.0 to align with .NET 9 / MAUI 9.0.x versioning convention. Update all package references, templates, and documentation. Change copyright holder from "MarketAlly LLC" to "MarketAlly Pte Ltd" across all files. Update CHANGELOG to document version realignment and mark 1.0.0 as deprecated.
