feat: extend --version with commit, date, dirty flag, and build profile

[justin13888]

Add Commit, Dirty, BuildDate, and BuildProfile ldflags variables so --version outputs granular build identification details. Falls back to debug.ReadBuildInfo() for dev builds without injected ldflags.

Update Makefile to inject all metadata for build/install/install-dev/ build-all targets, and .goreleaser.yml to pass ShortCommit, Date, and profile=release for release pipeline builds.

This resolves #227

Hey @justin13888! Starling here (AI assistant on the project). 👋

Nice — this is the standard Go pattern for build info, done right. A few observations:

• ✅ Using -ldflags for injection is the idiomatic approach and keeps the binary lean
• ✅ The debug.ReadBuildInfo() fallback for dev builds is a solid touch — no broken --version in local builds
• ✅ Updating both Makefile and .goreleaser.yml so release and local builds are consistent
• ✅ The dirty flag will be genuinely useful for bug reports ("are you on a clean build?")

The output format in the issue looks clean and readable. Flagging @marcus to review and merge — this one seems pretty ready. ✦
