kdeldycke/meta-package-manager: v6.6.0

• Breaking: [mpm] Rename the global --stats / --no-stats flag to --summary / --no-summary. Scripts passing the old flag must update.
• Breaking: [mpm] Move cyclonedx-python-lib and spdx-tools into a new [sbom] extra: mpm sbom now requires pip install meta-package-manager[sbom]. packageurl-python stays in the runtime install. The standalone binary distribution keeps shipping SBOM support: [tool.repomatic] nuitka.extras = ["sbom"] syncs the extra into the build venv and [tool.nuitka] include-package = ["cyclonedx", "spdx_tools"] forces Nuitka to bundle the try/except-guarded imports.
• [asdf] Add asdf package manager (installed, outdated, search, install, upgrade, upgrade_all, remove, sync) on Linux and macOS; requires asdf >=0.16.0.
• [mise] Add mise package manager (installed, outdated, search, install, upgrade, upgrade_all, remove, sync, cleanup), cross-platform; requires mise >=2025.5.10.
• [mpm] Add the --man (roff man page) and --accessible (no ANSI or Unicode, for screen readers) global options from click-extra, and attach an mpm-manpages.tar.gz asset to each release.
• [mpm] Add a --cooldown DURATION option and [mpm] cooldown config to refuse installing or upgrading package versions newer than a given release age, as a supply-chain mitigation; unsupported managers are skipped unless --allow-no-cooldown.
• [brew] Adapt to Homebrew 6.0.0: pass --yes to brew upgrade to suppress the new interactive prompt, and trust tap-qualified installs before installing to avoid tap trust is required aborts. Bumps minimum brew from 2.7.0 to 6.0.0.
• [zerobrew] Add upgrade and upgrade_all support via zb upgrade, and bump minimum zb from 0.2.0 to 0.3.0.
• [mpm] Make mpm sbom maximalist by default, collecting rich per-package metadata (license, supplier, homepage, checksums, dependency graph) into SPDX and CycloneDX exports, with --minimal for the bare inventory.
• [mpm] Attach canonical SPDX URLs to each identifier inside compound license expressions in CycloneDX 1.7 output (licenses[].expressionDetails[]).
• [mpm] Reduce default-verbosity noise on operational subcommands: captured stderr and implicit-selection Skip messages drop to DEBUG, with a one-line error summary at the end of any subcommand whose CLIs accumulated errors.
• [mpm] Fix pkg:cpan/…, pkg:guix/…, and pkg:nix/… pURL specifiers raising Unrecognized pURL type even though those managers are implemented.
