Topic: Specialization panic blocking basic-cli (#10485)

Heads-up: today's nightly (1c1cecc) panics roc check on a List(OsStr) with two or more string literals — it's turning basic-cli's main and every open PR red (via examples/command.roc). Filed #10523.

Bisected to #10485 (checked-type-performance): good f5556d8 (yesterday's nightly) → bad c6dfe61b, which is the #10485 merge sitting directly on f5556d8. Minimal repro is in the issue — names : List(OsStr) = ["a", "b"] is enough to panic, while ["a"] checks clean.

Not urgent for me, just flagging since it blocks the whole repo until a fixed nightly lands.
