Cli parse refactor

[CodingInAVan]

Description

• Split launcher CLI parsing into focused modules:
  • cli_help.cpp for help text
  • cli_parse_internal.* for shared flag/value and numeric parsing
  • cli_trace_options.* for trace option registration and generated help
  • cli_subcommand_options.* for upload, monitor, and info registries
• Added reusable CliOptionManager<Args> with alias registration and duplicate-alias protection.
• Migrated upload, monitor, and info option dispatch to typed registries.
• Kept positional arguments, removed-option errors, and trace policy-heavy flags explicit.
• Generated trace’s simple option help from the same registry used for parsing.
• Hardened integer parsing against overflow while retaining supported leading-space and + forms.
• Added coverage for integer overflow, inline boolean values, and generated trace help.
