Remove the VIBE BI block-art header and marketing branding that was
added to all 17 assets in v3.10.3. Restore each SVG to its original
content focused on the feature it illustrates (chat demo, DAX
debugging, architecture flow, etc.) without the promotional overlay.
## Claude Code integration now fully opt-in (Fix 3)
- `pbi connect` no longer writes to ~/.claude/ automatically
- New `pbi-cli` entry point: `pbi-cli skills install/uninstall/list`
- `pbi-cli skills install` shows exact paths before writing and requires y/N confirmation
- `pbi connect` prints a one-line tip if skills are not yet installed
- `pbi skills` subgroup removed from the `pbi` entry point
## DLL licensing compliance (Fix 1)
- pyproject.toml updated to PEP 639 SPDX dual expression:
MIT AND LicenseRef-Microsoft-AS-Client-Libraries
- license-files declaration: LICENSE, THIRD_PARTY_LICENSES.md, NOTICE
- THIRD_PARTY_LICENSES.md: full verbatim MS Analysis Services Client Libraries EULA
- NOTICE: short-form attribution for wheel redistribution
- src/pbi_cli/dlls/README.md: in-directory sentinel for the MS DLLs
- setuptools requirement bumped to >=77.0 for PEP 639 support
## SECURITY.md rewrite (Fix 2)
- Supported versions table updated to 3.10.x
- Architecture section: no MCP server, no subprocess, direct pythonnet interop
- Global Configuration Modifications section updated to reflect opt-in model
- Bundled Binaries section references THIRD_PARTY_LICENSES.md
## Documentation
- README.md, README.pypi.md: corrected 3-step setup flow
- CHANGELOG.md: [3.10.3] entry
- CONTRIBUTING.md: pbi skills -> pbi-cli skills
- All 7 semantic model SKILL.md files: prerequisites updated to 3-step flow
