bug(repl): help text missing --json flag documentation #152
Description
Current Behavior
The REPL help text does not mention the `--json` inline flag. Users have no way to discover this flag from within the REPL.
Expected Behavior
The `--json` flag should be listed in the REPL help text alongside the other inline flags.
Context
Discoverability: users should be able to learn about available flags from the help text.
Technical Details
Relevant Code
`src/repl.rs` -- `print_help()`
The inline flags section lists `--include-dynamic`, `--top`, `--top-modules`, and `--ignore` but not `--json`.
