v0.3.3

Ships the 0.3.2 marketplace run-through fixes — all 8 issues resolved.

OCR-033 (#67) — sm hardened as the single install chokepoint (semantic_model.cli readiness + cwd path isolation + PEP-668 --break-system-packages tier); promote_credentials.py + setup_desktop_mcp.py migrated to the _agami_lib resolver + sm install delegation. Fixes real-DB credential promotion and /agami-serve on marketplace installs.

OCR-034 (#68) — sample "watch it build" (6B) codifies its carve-outs and opens the model-explorer; the preflight no longer invents a main profile on first run; agami-query guardrail against hand-rolled model dumps.
