Pull request overview

Bumps the project to v0.4.0 while reorganizing and documenting the public module surface (notably moving literals to a top-level module), plus expanding examples/tests to cover the newer conversion/algorithms APIs.

Changes:

• Bump project version to 0.4.0 in both xmake and CMake.
• Rename/export literals as mcpplibs.primitives.literals and update imports/tests/docs accordingly.
• Add new examples (ex06_conversion, ex07_algorithms) and wire literals tests into the basic test suites.
