v0.17.3

Added

• Volt.Builder accepts importer-scoped package directories through :package_scopes.
• Volt.NPM.install!/2 exposes isolated, npm_ex-backed package acquisition for frameworks and plugins.
• Volt.Priv.render!/4 applies literal bindings and AST splices while preserving TypeScript for a subsequent Volt build.

Fixed

• Preserve importer package scopes while resolving transitive package imports.
• Invalidate cached Volt.Priv templates and compiled modules when their source changes.
• Type-check the private test-entry splice placeholder without changing rendered output.

Changed

• Require Elixir 1.18 and Erlang/OTP 27, and verify those minimum versions in CI.
