Adds DirtyFingerprint package var (default "") and a composeVersionDisplay()
helper implementing the same strip-and-append rule as the C daemons: strips
a trailing -dirty from GitCommit and appends -<fingerprint> when available,
via a genuine anchored strings.TrimSuffix, not a blind substring replace.
GitCommit's declaration and the logger.Info startup-log call site (with its
zap fields) are completely untouched.
New main_test.go covers 6 cases via table-driven tests. Verified independently
by review, including a self-constructed mutation test (distinct from the
implementer's own) proving the anchored-suffix regression test is genuinely
meaningful, a real build across all 5 ldflags scenarios, and a live daemon
startup-log capture confirming no leak into the log even on the same binary
whose -version output shows the fingerprint.

Declares GitCommit/BuildTime package vars (default "unknown", target of
task 4.1's -ldflags -X injection), a -version flag checked before
utils.PromptForTopDir()/InitLogger() (zero filesystem side effects), and
extends the existing "Initialize Logger done!" startup log line with
zap.String structured fields carrying both values, per design.md's
explicit mandate.
Live-verified end to end: -version output and the startup log's first
line are byte-identical, with a real commit id (matching
git rev-parse --short HEAD plus dirty suffix) and UTC timestamp -- the
first full round-trip proof in this spec (earlier Go tasks could only
verify via linked build-info metadata, since no consuming vars existed
yet).
Task 4.4/13 of build-time-versioning.

- add heartbeat.go with heartbeatIntervalSecs var, SetHeartbeatInterval, runHeartbeat (no build tag, CGO-free)
- add heartbeat_test.go with 5 tests covering interval validation and goroutine lifecycle
- add StartHeartbeat to clib.go (CGO impl calling xcecli_heartbeat)
- remove SetHeartbeatInterval stub from stub.go (now real code in heartbeat.go)
- remove TestSetHeartbeatInterval_StubNoOp from stub_funcs_test.go
- call SetHeartbeatInterval in OnClusterUpdated to track backend-pushed interval
- call backend.StartHeartbeat in cmd/main.go after backend registration
