feat(manifest): add Go import aliases

[akonwi]

Summary

• add [go.imports] manifest mappings for stable Go package aliases
• expand aliases as package-path prefixes in root projects and Ard dependencies
• reserve the Ard project name for project-local FFI shorthand
• invalidate LSP analyses when path dependency manifests change
• document alias behavior and go.mod ownership

Example

[go.imports]
vaxis = "go.rockorager.dev/vaxis"

use go:vaxis
use go:vaxis/widgets

Testing

• cd compiler && go test ./... -count=1
• cd compiler && gopls check manifest/manifest.go manifest/manifest_test.go checker/module_resolver.go checker/go_packages_resolver_test.go go/project_go_import_alias_test.go lsp/analysis/engine.go lsp/analysis/engine_test.go
• cd website && npm run build
• checked Cooper directly and through cooper/examples as a path dependency using a temporary manifest alias
