chore: simplify and clean up build and release processes

- Update `GOFMT` command to include `-s` and `-w` flags
- Remove redundant `DIST` and `DIST_DIRS` definitions
- Remove unused variables and dependencies
- Remove `.PHONY` targets and associated release tasks
- Simplify `clean` target by removing `$(DIST)` directory from the removal list
