Constants the operator/test reader benefits from centralising.
Tests stay verbatim (the .golangci.yaml goconst tune skips them);
extraction here applies only where the same literal acts as
shared vocabulary across files.
cmd/headscale/cli/strings.go (new)
Cobra subcommand verbs and aliases shared by every list / show
/ new / delete / expire command across api_key, nodes, policy,
preauthkeys, users — plus the Result / Created / Expiration
column headers used in printOutput maps.
hscontrol/templates/design.go
cssBorderHS, cssBreakWord, cssCenter, cssOverflowWrap — shared
styles applied across design.go, ping.go, register_confirm.go.
spaceS already existed; switch raw "0.5rem" literals to it.
integration/hsic/hsic.go
binHeadscale, flagOutput, acceptJSON — names invoked across
hsic.go and config.go.
integration/tsic/tsic.go
tailscaleBin — used across docker exec call sites.
