Replace `tool/update-deps` with a Ruby source scanner so dependency updates no longer require GNU make, a configured build, or compiler preprocessor output. Keep compact source mappings and scanner declarations in dependency files, and expand complete rules into the build directory. Avoid the temporary fixture headers required by the compiler-driven prototype. Use the generated rules from GNU make, BSD make, and NMake builds. Support out-of-tree and read-only source trees, and retain expanded dependencies shipped in release archives when baseruby is unavailable.
