Adds a CI check to keep opted-in directories' README.md files in sync
with their package godoc. For now tsnet (and its sub-packages under
tsnet/example) is the only opted-in tree. The list of directories
lives in misc/genreadme/genreadme.go as defaultRoots, so CI and humans
both just run `./tool/go run ./misc/genreadme` with no arguments.
The check piggybacks on the existing go_generate job in test.yml and
fails if any README.md is out of date, pointing the user at the same
command.
Along the way:
- tempfork/pkgdoc now emits Markdown instead of plain text: headings
become level-2 with no {#hdr-...} anchors, and [Symbol] doc links
resolve to pkg.go.dev URLs, including for symbols in the current
package (which the default Printer would otherwise emit as bare
#Name fragments with no backing anchor in a README). Parsing no
longer uses parser.ImportsOnly, so doc.Package knows the package's
symbols and can resolve [Symbol] links at all.
- genreadme also emits a pkg.go.dev Go Reference badge at the top of
a library package's README; suppressed for package main.
- tsnet/tsnet.go's package godoc is expanded in idiomatic godoc
syntax — [Type], [Type.Method], reference-style [link]: URL
definitions — rather than Markdown-flavored [text](url) or
backtick-quoted identifiers, so that both pkg.go.dev and the
generated README.md render cleanly from a single source.

tsnet-services
The tsnet-services example demonstrates how to use tsnet with Services.
To run this example yourself:
- Add access controls which (i) define a new ACL tag, (ii) allow the demo node to host the Service, and (iii) allow peers on the tailnet to reach the Service. A sample ACL policy is provided below.
- Generate an auth key using the Tailscale admin panel. When doing so, add your new tag to your key (Service hosts must be tagged nodes).
- Define a Service. For the purposes of this demo, it must be defined to listen on TCP port 443. Note that you only need to follow Step 1 in the linked document.
- Run the demo on the command line (step 4 command shown below).
Command for step 4:
TS_AUTHKEY=<yourkey> go run tsnet-services.go -service <service-name>
The following is a sample ACL policy for step 1:
"tagOwners": {
"tag:tsnet-demo-host": ["autogroup:member"],
},
"autoApprovers": {
"services": {
"svc:tsnet-demo": ["tag:tsnet-demo-host"],
},
},
"grants": [
"src": ["*"],
"dst": ["svc:tsnet-demo"],
"ip": ["*"],
],
