Version string maintained in two places

[dbravender]

Priority: Low

Description

var version = "0.7.0" is hardcoded in main.go:16. The release pipeline overrides it via -ldflags, but local builds and --version during development show whatever is in source. This means the version needs to be bumped in both the source file and the git tag.

Suggested fix

Default to "dev" in source and only set the real version via ldflags — one source of truth:

var version = "dev"
