Resolve the zcode test cascade exposed by gsd-test: - model-catalog.json: add zcode runtimeTierDefaults (null tiers, matching the other profile-marker-only runtimes) so KNOWN_RUNTIMES stays parity with allRuntimes. - runtime-name-policy: add zcode to GLOBAL_CONFIG_HOME_FRAGMENTS (~/.zcode) so getGlobalConfigHomeFragment stops falling through to the .claude default. - installer-migration-install: add the zcode fresh-install contract (flat-skills, no settings, no package.json — same shape as trae). - golden-install-parity: capture the zcode fixture via a standalone generator script (not node --test — the gate stays gsd-test). - capability-matrix.md: regenerate so zcode appears as a first-party row. Fluidify the remaining count-pinned guards so adding a runtime no longer trips a hand-pinned snapshot: gemini-runtime-removed (flag count derives from the registry), non-claude-runtimes-registry-derivation (golden list derived from the registry).
