Summary

Enhances the interactive Support Case Wizard (myf5 cases create) and case commenting (myf5 cases comment) with a robust multiline text buffer, in-buffer commands (undo, preview, external editor, clear, back), and seamless bidirectional step navigation across all wizard steps.

Key Changes

1. Multiline Text Buffer (promptMultilineBuffer):

   • Accidental-Enter Protection: Pressing Enter on an empty line in multiline mode prompts with inline guidance rather than accepting premature or default input. Input is completed with a single period (.) on a line or :done.
   • Line-Numbered Prompting: Displays [1] > , [2] > , etc. for clear orientation.
   • Interactive Commands:
     • :u / :undo: Pops and removes the last entered line from the buffer.
     • :p / :show / :list: Displays the current buffer contents formatted with line numbers.
     • :e / :edit: Spawns the user's preferred external editor ($EDITOR, nano, vim, or notepad) with current buffer contents, seamlessly re-reading edits on exit.
     • :c / :clear: Clears the multiline buffer.
     • :b / :back / :cancel: Exits buffer and returns to the previous field or wizard step.
     • :h / :help / ?: Displays buffer command help.

2. Bidirectional Step & Field Navigation:

   • Refactored RunCaseWizard into a state machine loop tracking step and startField.
   • Returning from Step 4 (Contact Details) lands directly on Step 3 field 4 (Description), rather than resetting the step.
   • Returning from Step 3 (Case Details) lands on Step 2 field 4 (Entitlement).
   • Typing b in Step 5 (Review & Submission) returns to Step 4 to allow editing contact details.

3. Interactive Multiline Commenting:

   • When myf5 cases comment <case-number> is invoked without a note argument in an interactive terminal, launches the multiline buffer for composing notes.
   • Displays a formatted preview of the note and requires explicit confirmation (Submit this comment to case <case-number>? [y/N]) before making any API request.

4. TTY Auto-Detection for Case Creation:

   • Running myf5 cases create without flags in a terminal detects interactive TTY and prompts No case parameters specified. Launch interactive Support Case Wizard? [Y/n]: . Non-interactive calls cleanly print usage.

5. Testing & Security:

   • Added comprehensive tests for multiline buffer commands (:u, :p, :c, :b, :done), bidirectional step transitions, non-TTY execution, and comment usage.
   • Zero secrets logged or accepted in command-line arguments.
   • Dry-run and offline safety verified: zero live case creation or comment submission in tests.
   • Passes all linters, go test -v -race ./..., and OAS validator.
