Add -f/--full option to force full project compile from CommandRunner compile

[Copilot]

Compilation currently favors incremental/single-source behavior by default, with no explicit way to request a full rebuild. This change introduces an opt-in full compile flag while preserving existing default behavior.

• CLI behavior

  • CommandRunner compile now accepts -f / --full.
  • Updated usage/help text to document:
    • CommandRunner compile <filename> [-f|--full]

• Compile mode split

  • Default mode (unchanged): compiles only the provided source file’s unit/types.
  • Full mode (-f/--full): recursively scans src/main for .cod files and compiles discovered types into the project container.

• Full compile semantics

  • Aggregates compile results across all discovered files.
  • Skips synthetic default units (no stable container entry path).
  • Emits concise full-compile summary + failure count warning when applicable.

# Existing behavior (unchanged)
java -cp Coderive.jar cod.runner.CommandRunner compile src/main/foo/Bar.cod

# New: force full compile
java -cp Coderive.jar cod.runner.CommandRunner compile src/main/foo/Bar.cod -f
# or
java -cp Coderive.jar cod.runner.CommandRunner compile src/main/foo/Bar.cod --full
