Fix BATS test suite after v2 YAML package manager refactor

- Load v2 configs from plonk.yaml in all operations (install, uninstall, upgrade, apply)
- Fix config merging to preserve user-defined managers alongside defaults
- Add idempotency patterns to all 8 default package managers
- Handle idempotent success messages (already installed/up-to-date) in GenericManager
- Add require_command helper to test_helper.bash
- Add install/uninstall tests for pipx, pnpm, and conda (full 8 manager coverage)
- Add bounds check in GenericManager.Install to prevent panic on empty commands
- Update safe-packages.list with cargo:bat, uv:httpx, conda:jq
- Remove flaky/environment-specific test assertions
- Remove custom manager BATS tests (covered by unit tests)
- Fix conda tests to use conda:jq (available in defaults channel)

All unit tests pass. BATS suite now has 125+ passing tests.
