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fails if any README.md is out of date, pointing the user at the same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.

When the repo is checked out as a nested worktree, a go.work in the
outer tree hijacks module resolution, which makes the rebuild fails
with "main module does not contain package." Set GOWORK=off for the
build since the hook is self-contained.
Bumps HOOK_VERSION so existing installs pick up the fix.

(#19440)
Pull the hook logic into a reusable githook library package so
tailscale/corp can share it via a thin wrapper main instead of
keeping a forked copy in sync.
The install flow also changes: a wrapper scripts now build the
binary and reinstall the git hooks. Pulling new shared code no
longer requires re-running the installer.

Add misc/install-git-hooks.go and misc/git_hook/ to the OSS repo,
adapted from the corp repo. The primary motivation is Change-Id
generation in commit messages, which provides a persistent identifier
for a change across cherry-picks between branches.
The installer uses "git rev-parse --git-common-dir" instead of go-git
to find the hooks directory, avoiding a new direct dependency while
still supporting worktrees.
Hooks included:
- commit-msg: adds Change-Id trailer
- pre-commit: blocks NOCOMMIT / DO NOT SUBMIT markers
- pre-push: blocks local-directory replace directives in go.mod
- post-checkout: warns when the hook binary is outdated
Also update docs/commit-messages.md to reflect that Change-Id is no
longer optional in the OSS repo.
