fix: remove rootCmd.SetVersionTemplate(...) to reduce binary size

[narenaryan]

Description

v1.4.0 introduced a binary inflation problem (~1.5 MB bump per binary).

The fix is to remove rootCmd.SetVersionTemplate(...) Cobra template entirely and implement custom arg handling.

Confidence Score: 5/5

Safe to merge — the change is a targeted replacement of Cobra's version-template mechanism with an equivalent custom flag and handler.

Both the --version/-V flag path and the version subcommand call cliVersion() through the same fmt.Fprintln call, so the output is guaranteed identical. The test now validates all three entry points for both content and format. No existing behaviour is regressed; the only observable difference is the removal of the Cobra-generated version-flag line from --help output and the addition of -V as the short form.

No files require special attention.

Important Files Changed

Filename	Overview
main.go	Removes Cobra version template plumbing; adds a local BoolP flag + Run handler that mirrors the existing version subcommand. Logic is straightforward and correct.
main_test.go	Adds -V coverage, a HasPrefix assertion for the new output format, and a cross-invocation consistency check. Test structure is sound.
