fix(workflows): strip inline comments from VERSION; preserve operator; fix e2e output path

- shared-release: strip inline Makefile comments (e.g. '# comment') from
  the VERSION value before semver validation to avoid false parse failures
- shared-release: preserve the original assignment operator (?=, :=, =)
  when rewriting VERSION in the Makefile instead of normalising to '='
- e2e/action: output E2E_REPORT_PATH (.json report) instead of
  CONTROLLER_LOGS_PATH (.txt logs) to match the declared output description
