fix(build): allow metadata-only application builds

[zackarychapple]

What changed

• add Attributes::build_application_artifacts(bool), defaulting to true
• when disabled, retain configuration validation, ACL generation, global API scripts, target metadata, and optional codegen
• skip final-application work: Android project mutation, sidecar/resource/framework staging, and platform-specific executable link/deployment configuration
• preserve existing behavior for every caller that does not explicitly opt out

Why

A library-only package may need tauri_build::try_build for ACL/context metadata without owning an application executable. Running the existing application-artifact path from that package can emit invalid binary-only Cargo directives and create unordered duplicate writers for staged app payloads.

The real application package remains on the default-enabled path, so this changes no normal Tauri build pipeline.

Validation

• cargo +stable fmt --package tauri-build -- --check
• cargo +1.88.0 test -p tauri-build --all-features --locked — 10 unit tests plus doctest
• cargo +1.88.0 clippy -p tauri-build --all-targets --all-features --locked --no-deps -- -A clippy::uninlined-format-args -D warnings
• cargo +nightly-2026-05-05 check -p tauri-build --target x86_64-pc-windows-msvc --all-features --locked
• change-tag validation
• independent metadata-only fixture on a Windows target and macOS host
