Adds DirtyFingerprint var and composeVersionDisplay() helper to
xcecli/cmd/main.go, a logical duplicate of apiserver's just-approved
implementation (task 4.4, same anchored strings.TrimSuffix strip-and-
append rule). Applied at the sole consumption point: the version string
fed into router.Execute(cm, version), which sets Cobra's rootCmd.Version.
router.go is untouched -- xcecli has no startup log to protect, already
established out of scope by the original build-time-versioning feature.
New main_test.go covers the same 6 cases as apiserver's tests. Verified
independently by review (including a second, independent mutation test)
with real builds across all 3 required scenarios and a full xcecli module
test suite run showing no regressions.
This completes all Go binary work (tasks 4.1-4.5) for this spec.

Adds GitCommit/BuildTime vars to xcecli's main.go. Cobra's rootCmd is
declared unexported in router.go (a different file than the task's
original main.go-only boundary), so main.go can't reach it directly --
resolved by extending router.go's sole exported entry point,
Execute(cm, version), to accept the composed version string and set
rootCmd.Version before rootCmd.Execute() runs. Cobra then auto-registers
--version/-v natively once rootCmd.Version is non-empty (confirmed via
reading Cobra v1.9.1 source directly) -- zero additional flag-parsing
code, as designed.
Live-verified via both build paths (meson xce-build.sh and make
build-cli): real commit id (matching git rev-parse --short HEAD plus
dirty suffix) and build time, exit 0.
xcecli's startup log deliberately not extended -- Requirement 3 scopes
that to the four daemons only; xcecli is a one-shot CLI. Corrects a
stale design.md line that had assumed otherwise.
Task 4.5/13 -- closes out the Go binary version display phase (tasks
4.1-4.5).
