John Kerl 2f3e54d1f6 Remove os.Exit callsites below the entrypoint: phase 4 (plans/exit.md) (#2205) ... Phase 4 of plans/exit.md: the aux/terminal sub-entrypoints. pkg/auxents and pkg/terminals are now os.Exit-free; even the dispatchers return exit codes instead of exiting. - auxents.Dispatch returns (handled bool, exitCode int); entrypoint.Main -- the one sanctioned exit point -- exits with the code. - terminals.Dispatch returns an exit code; the climain caller wraps it in a lib.ExitRequest, which also retires the 'terminal did not exit the process' panic. - Usage functions (hex, unhex, lecat, termcvt, repl, script, regtest) no longer take an exitCode parameter and exit; call sites print usage and return the code explicitly. - Inner I/O helpers (hexDumpFile, unhexFile, lecatFile, termcvtFile) return errors; each sub-main prints 'mlr {verb}: ...' as before and returns 1. lecatFile formerly looped forever on a non-EOF read error; it now returns the error. - The regtest directory walk (Execute / executeSinglePath / executeSingleDirectory / hasCaseSubdirectories) plumbs errors up to RegTestMain; regression_test.go updated for the new Execute signature. Stderr messages and exit codes are unchanged across mlr aux-list, hex, unhex, lecat, termcvt, help, version, repl, script, and regtest surfaces (checked by hand); all 4779 regression cases pass; make lint is clean; docs rebuild with zero churn.
