the lunchcat org and lunchcat.dev are inactive, so point the repo
link at github.com/vmfunc/sif and drop the dead lunchcat.dev support
link.
- Makefile: repo url -> vmfunc/sif; drop the lunchcat.dev line
- README + .all-contributorsrc: contributor links and projectOwner ->
vmfunc
- config: drop "lunchcat" from the -api flag help text
copyright and attribution to lunchcat are kept for continuity
(license headers, LICENSE, man page) per the issue.
fixes#50
- add internal/version: resolve from the release ldflag, else the go build
info (module tag / vcs revision), else "dev"
- show the version on the boot banner and for `sif version`
- Makefile now stamps `make` builds via git describe (matching the release ci),
so local/go-install builds report a real version instead of "dev"
- patchnotes.ShowOnce skips pseudo/dev versions so non-release builds dont make
a doomed github call
- document sif version / sif patchnote / SIF_NO_PATCHNOTES in the readme + usage
adds man/sif.1 covering the targets/scans/options/modules flags, the
patchnote and version commands, env vars (incl SIF_NO_PATCHNOTES), and a
few examples. the install/uninstall make targets now drop it in
$(PREFIX)/share/man/man1.
