chore(index): add tinyhttps 0.2.9

[Sunrisepeak]

Summary

• add mcpplibs.tinyhttps@0.2.9 to Linux, macOS, and Windows descriptors
• publish the exact GitHub tag archive to mcpp-res/tinyhttps@0.2.9
• add deterministic module API coverage and run it on all three CI workspace platforms

Package shape

• upstream mcpp project / external Form A module repository
• upstream tag 0.2.9 points to 965d805050d02fd6ed244473a6a68b6ace4bf032
• no index-level optional source feature is needed
• README already lists mcpplibs.tinyhttps in the Form A package table, so no duplicate catalog row was added

Artifact evidence

• GLOBAL downloaded independently twice
• GLOBAL SHA256: b17e0b15d2c205a2918708bcd3ac992384f1a38d03232c28f17190a1db081e54
• CN URL returned HTTP 200
• freshly downloaded CN asset is byte-identical to GLOBAL and has the same SHA256

Local verification

• all descriptor Lua syntax and mirror lint: passed
• all descriptors parsed by CI-pinned mcpp 0.0.87: passed
• tests/smoke_tinyhttps_module.sh: 1 passed; 0 failed
• workflow YAML, smoke shell syntax, and git diff --check: passed

The dedicated smoke reseeds the builtin mcpplibs index from this checkout before testing. This is required because mcpp intentionally treats that namespace as builtin and does not override it through a workspace path index.
