ci: add pr bot for auto-labeling + rewrite release workflow for semver tags

pr-bot labels PRs by area (scan, nuclei, modules, ci, deps, etc) and size (xs/s/m/l/xl), posts a summary comment with file stats breakdown. release workflow now triggers on v* tags instead of every push to main - extracts version from tag, injects via ldflags, auto-generates changelog from commits since last release, includes install instructions in the release body. prerelease detection for rc/beta tags.
