Merge branch 'cli-upgrade' into ship-42-43

1	+	//! `g1t upgrade`: the CLI updates itself to the newest release, and says
2	+	//! now and then, in a terminal, that a newer one is out.
3	+	//!
4	+	//! Releases are at `https://g1t.sh/downloads/cli/` (`G1T_DOWNLOAD_URL`
5	+	//! names another, as for the install scripts): `latest.json`, the newest
6	+	//! release's manifest, and `latest.json.sig`, its Ed25519 signature with
7	+	//! g1t's release key (scripts/cli-release.mjs). The CLI trusts a manifest
8	+	//! only when the signature checks out against the key built into it
9	+	//! (`G1T_RUNNER_RELEASE_KEY` when it was built), and installs a download
10	+	//! only when its SHA-256 is the manifest's. A build without the key, such
11	+	//! as one built from source, cannot upgrade itself and says how to.

	41	+	version other than the latest.
	42	+
	43	+	### Upgrade
	44	+
	45	+	From 0.3.4 on, `g1t upgrade` updates g1t to the newest release:
	46	+
	47	+	```sh
	48	+	g1t upgrade # download and install the newest release
	49	+	g1t upgrade --check # only say whether there is one
	50	+	```
	51	+
	52	+	It reads the newest release's manifest, `latest.json`, and checks its
	53	+	signature (`latest.json.sig`) against g1t's release key, which is built
	54	+	into every release. It then downloads the build for your system, checks
	55	+	its SHA-256 against the manifest, and puts it where the running `g1t` is.
	56	+	If anything does not check out, nothing changes. Releases come from
	57	+	`https://g1t.sh/downloads/cli`, or from `G1T_DOWNLOAD_URL` if you set it.
	58	+
	59	+	In a terminal, g1t looks for a newer release about once a day, in the
	60	+	background, and says so after a command when there is one. It never looks
	61	+	in CI or when its output is not a terminal. Set `G1T_NO_UPDATE_NOTIFIER=1`
	62	+	to turn it off.
	63	+
	64	+	A g1t built from source has no release key and cannot upgrade itself.
	65	+	Neither can versions before 0.3.4. Update those by running the install
	66	+	script again.
