* Initial plan

* Fix FindCompileCommands to handle absolute paths in c_build_dir_names

Use ale#path#GetAbsPath to resolve build directory paths, which correctly
handles both absolute and relative paths. When the dirname is absolute,
derive the project root from the parent of the build directory.

* Improve comment clarity in FindCompileCommands

* Add defensive ale#Set for c_build_dir_names in FindCompileCommands

Mirror the existing s:CanParseMakefile pattern to ensure the
g:ale_c_build_dir_names variable always exists when ale#Var is
called, even if test Save/Restore cycles delete it.
