fix(ci): force-reinstall rust-std for target (win-arm64 E0463 fix)

[zackees]

soldr#1006 Lane 2 third attempt. v2.3.9 win-arm64 failed with E0463: can't find crate for 'core' despite rustup target add reporting "is up to date" — setup-soldr's thin-mode build cache trimmed the .rlib files while leaving rustup's manifest entry. Fix: remove + add forces actual file reinstall.

📝 Walkthrough

Walkthrough

The "Add Rust target" CI step is changed from a single rustup target add <triple> to a rustup target remove <triple> || true && rustup target add <triple> sequence, with inline comments documenting the rationale around stale cache states leaving rustup manifests inconsistent.

Changes

Rustup Target Installation Fix

Layer / File(s)	Summary
Remove-then-add Rust target step .github/workflows/template_native_build.yml	Replaces rustup target add with a remove (|| true) then add sequence; adds comments explaining that cached rustup manifests can claim a target is installed while rust-std artifacts are absent, notably for aarch64-pc-windows-msvc.

Poem

🐇 A target once cached left the stdlib astray,
So the rabbit said "remove it first, then add today!"
With || true as a shield against failure's sting,
Remove then re-add — let the compiler sing!
No phantom installs shall fool our CI ring! 🎉
