refactor: rename subcommand structs (#15309)

Came from [this
discussion](https://discord.com/channels/601130461678272522/1348791953784836147/1349699872059691038)
on discord with @fdncred

# Description
Small refactoring where I rename commands from "SubCommand" to its
proper name. Motivations: better clarity (although subjective), better
searchable, consistency.

The only commands I didn't touch were "split list" and "ansi gradient"
because of name clashes.

# User-Facing Changes
None

# Tests + Formatting
cargo fmt and clippy OK

# After Submitting
nothing required
