Move HOOK_VERSION into the githook package and export it as githook.HookVersion, so tailscale/corp can reference it via the shared-code bump instead of having to bump HOOK_VERSION by hand. New launcher.sh composes the wanted version from 2 sources: the shared HOOK_VERSION and an optional repo local version, misc/git_hook/HOOK_VERSION, for repo-specific config bumps.

# ts-git-hook launcher (installed at .git/hooks/ts-git-hook).
|
|
#
|
|
# Written by misc/install-git-hooks.go from the canonical copy embedded
|
|
# in tailscale.com/misc/git_hook/githook. On every invocation it:
|
|
#
|
|
# 1. Compares the binary's reported version against the shared
|
|
# githook HOOK_VERSION (resolved via `go list -m tailscale.com`)
|
|
# plus the repo-local HOOK_VERSION.
|
|
# 2. If stale or missing: rebuilds ts-git-hook-bin and runs
|
|
# `ts-git-hook-bin install`.
|
|
# 3. Execs the binary with the hook's args.
