feat(runtime): write runtime diagnostics to stderr
Runtime check messages and the unhandled-exception message were printed
to stdout by the generated program, so `cpsc x.cps -r >out.txt` captured
them. They are now formatted with snprintf and written with write(2).
Test expectations and docs are updated accordingly.

With multiple input files, lexer, parser and code generation diagnostics include the source path after the line number. Failed source compilation does not write output; failed native linking does not replace an existing output file. Successful compilation overwrites an existing output file, but an output path that refers to any input source file (including a symbolic or hard link) is rejected. Runtime diagnostics of the compiled program (for example `[Fatal] line N: ...` and `Unhandled exception. Program terminated.`) are also written to stderr, so `OUTPUT` text alone appears on stdout. Missing input, including invoking `cpsc` without arguments, reports `cpsc: fatal error: no input files`. Ordinary lexical, syntax and semantic errors use `error:`; failures that prevent compilation, such as file I/O errors, use `fatal error:`. Compilation and argument failures end with one `compilation terminated.` line. Execution-stage failures do not print that line. |
