John Ericson eb7d7780b1 Rename doc/manual{src -> source}
This is needed to avoid this
https://github.com/mesonbuild/meson/issues/13774 when we go back to
making our subproject directory `src`.

## `manifest.json`
The manifest file records the provenance of the packages that are installed in a [profile](./profiles.md) managed by [`nix profile`](@docroot@/command-ref/new-cli/nix3-profile.md) (experimental).
Here is an example of what the file might look like after installing `zoom-us` from Nixpkgs:
```json
{
"version": 1,
"elements": [
{
"active": true,
"attrPath": "legacyPackages.x86_64-linux.zoom-us",
"originalUrl": "flake:nixpkgs",
"storePaths": [
"/nix/store/wbhg2ga8f3h87s9h5k0slxk0m81m4cxl-zoom-us-5.3.469451.0927"
],
"uri": "github:NixOS/nixpkgs/13d0c311e3ae923a00f734b43fd1d35b47d8943a"
},
]
}
```
Each object in the array `elements` denotes an installed package and
has the following fields:
* `originalUrl`: The [flake reference](@docroot@/command-ref/new-cli/nix3-flake.md) specified by
the user at the time of installation (e.g. `nixpkgs`). This is also
the flake reference that will be used by `nix profile upgrade`.
* `uri`: The locked flake reference to which `originalUrl` resolved.
* `attrPath`: The flake output attribute that provided this
package. Note that this is not necessarily the attribute that the
user specified, but the one resulting from applying the default
attribute paths and prefixes; for instance, `hello` might resolve to
`packages.x86_64-linux.hello` and the empty string to
`packages.x86_64-linux.default`.
* `storePath`: The paths in the Nix store containing the package.
* `active`: Whether the profile contains symlinks to the files of this
package. If set to false, the package is kept in the Nix store, but
is not "visible" in the profile's symlink tree.
