Valentin Gagarin 2af9fd20c6 clarify definition of "installable"
the term was hard to discover, as its definition and explanation were in
a very long document lacking an overview section.
search did not help because it occurs so often.

- clarify wording in the definition
- add an overview of installable types
- add "installable" to glossary
- link to definition from occurrences of the term
- be more precise about where store derivation outputs are processed
- installable Nix expressions must evaluate to a derivation

# Examples
* Delete a specific store path:
```console
# nix store delete /nix/store/yb5q57zxv6hgqql42d5r8b5k5mcq6kay-hello-2.10
```
# Description
This command deletes the store paths specified by [*installables*](./nix.md#installables),
but only if it is safe to do so; that is, when the path is not
reachable from a root of the garbage collector. This means that you
can only delete paths that would also be deleted by `nix store
gc`. Thus, `nix store delete` is a more targeted version of `nix store
gc`.
With the option `--ignore-liveness`, reachability from the roots is
ignored. However, the path still won't be deleted if there are other
paths in the store that refer to it (i.e., depend on it).
