feat: add slash commands (/help, /files, /clear) to interactive Q&A mode

[Arthur742Ramos]

Summary

Interactive Q&A mode — bootcamp ask <repo> and bootcamp <repo> --interactive — previously only recognized exit/quit. It now supports a small set of slash commands that make the REPL more discoverable and useful:

Command	Aliases	Action
/help	/?	Show the command reference
/files		List the detected repository files
/clear		Clear the screen
/exit	/quit, exit, quit	End the session

Unknown slash commands (e.g. /bogus) are reported with a hint rather than being silently sent to the assistant as a prompt.

Implementation

The core is a pure, exported classifyInteractiveInput(raw) that returns a discriminated union — empty | exit | command | unknown-command | question — plus pure renderInteractiveHelp() and renderFileList(scan) renderers. All three are unit-testable without an LLM session. The REPL loop simply dispatches on the classification result, so the conversational path is unchanged for normal questions.

Testing

• 15 unit tests: every input kind, command aliases, case-insensitivity, trailing-arg capture, "question containing a slash is not a command", and the help/file-list renderers (including truncation and empty-scan cases).
• 1 E2E test: drives the real ask process through /help, /files, and an unknown command via stdin, asserting the rendered output and a clean exit.
• Full suite green: npm test → 1119 passing; typecheck + lint + build clean.
