fix: sound meta signature and Justfile syntax

[SuaveIV]

I've updated the sound meta command to be less restrictive about its pipeline input. Previously, it only accepted Nothing or Binary, which caused it to crash when strings were piped in (like when looping over files with each). It now accepts Any input, which brings it in line with the other commands and fixes the reported pipe issues.

I also noticed the Binary type was still listed in the signature even though the code explicitly rejects it for now, so I've removed that to keep the API accurate.

The Justfile had a couple of Nushell syntax errors in the release recipe that I've cleared up:

• Replaced the POSIX if/then/fi construct with a Nushell if block.
• Fixed a variable declaration that was using @$ instead of let.

Finally, I fixed a small copy-paste error in the sound meta help text where it was still saying "file to play" instead of "file to read."

In `@Justfile`:
- Around line 67-75: The release recipe is broken for Nushell because the block
closure is immediately followed by another command and the `let version` is
scoped to a subshell; fix by placing the entire flow inside a single Nushell
command block or use proper continuations so commands run in the same shell
context: ensure `cargo smart-release --update-crates-index --execute
--changelog-without commit-statistics --no-tag` runs after the if-block
(separated by `;` or newline), and compute `let version = (cargo pkgid | str
replace -r '.*#' '' | str replace -r '.*:' '')` in the same block so the `git
tag $"v($version)" -m $"Release v($version)"` and subsequent `git push origin
main` / `git push origin $"v($version)"` can access that variable (update the
recipe containing the if-check, the cargo smart-release invocation, `let
version`, and the git tag/push lines).
