Replace Apache-2.0 with CMSD-1.0, a source-available license designed
for transparency and ANSSI CSPN certification compatibility while
preserving all commercial rights.
New files:
- LICENCE-CMSD-1.0.md: French authoritative version
- LICENSE-CMSD-1.0.en.md: English informative translation
- LICENSING.md: License documentation and SPDX guidance
Updated README.md with prominent license notice showing:
- What users CAN do (study, audit, research, cite)
- What users CANNOT do (production use, redistribution, derivatives)
