PaperPilot v1.4.5

Added

• Release infrastructure refinement: scripts/release_everywhere.sh now supports end-to-end local validation + dry-run with clean push/PyPI gating.
• CLI/docs alignment clean-up: release helper examples now use version placeholders and avoid stale manual version pinning in docs.
• Publishing workflow polish: stable dry-run behavior and deterministic changelog extraction for GitHub release notes.

Changed

• Updated version tracking to keep pyproject.toml and literature_agent/__init__.py in sync during one-command release flows.
• Improved release safety: skip-push / no-pypi / dry-run semantics are now consistently applied across publishing stages.
