feat(FN-2308): add selectable scope to agent company imports

- Update AgentImportModal preview to preselect all agents and skills, support per-item toggles plus select-all/clear controls, and keep directory preview enabled when parsed files exist.
- Send selectedAgents and selectedSkills from paste, directory, and browse import flows, with dynamic import CTA labels and guardrails when nothing is selected.
- Extend /agents/import to accept selection filters, allow skill-only imports, and parse downloaded company archives directly without shell tar extraction.
- Expand dashboard import tests to cover directory parsing, subset selection, browse-mode skill visibility, and related UI/style assertions.
- Restore full-suite CLI test reliability by adding workspace alias mappings in vitest config and retrying slow cross-platform binary help probes.
