feat(cmake): add release packaging with symbol separation

Add CLICE_RELEASE option that enables LTO and produces two archives:
- clice.tar.gz: stripped binary + clang resource dir + config
- clice-symbol.tar.gz: debug symbols for crash analysis

Platform-specific symbol handling: objcopy on Linux, dsymutil on macOS,
PDB on Windows.
