Spec Add

$spec-add                                                     # Interactive wizard (all prompts)
$spec-add --interactive                                       # Explicit interactive wizard
$spec-add "Use async/await instead of callbacks"              # Direct mode (auto-detect type)
$spec-add -y "No direct DB access" --type constraint          # Auto-confirm, skip confirmation
$spec-add --scope global --dimension personal                 # Create global personal spec (interactive)
$spec-add --dimension specs --category exploration            # Project spec in exploration category (interactive)
$spec-add "Cache invalidation requires event sourcing" --type learning --category architecture

Input Parsing:
   |- Parse: rule text (positional argument, optional if --interactive)
   |- Parse: --type (convention|constraint|learning)
   |- Parse: --category (subcategory)
   |- Parse: --dimension (specs|personal)
   |- Parse: --scope (global|project)
   |- Parse: --interactive (flag)
   +- Parse: -y / --yes (flag)

Step 1: Parse Input

Step 2: Determine Mode
   |- If --interactive OR no rule text -> Full Interactive Wizard (Path A)
   +- If rule text provided -> Direct Mode (Path B)

Path A: Interactive Wizard
   |- Step A1: Ask dimension (if not specified)
   |- Step A2: Ask scope (if personal + scope not specified)
   |- Step A3: Ask category (if not specified)
   |- Step A4: Ask type (convention|constraint|learning)
   |- Step A5: Ask content (rule text)
   +- Continue to Step 3

Path B: Direct Mode
   |- Step B1: Auto-detect type (if not specified) using detectType()
   |- Step B2: Auto-detect category (if not specified) using detectCategory()
   |- Step B3: Default dimension to 'specs' if not specified
   +- Continue to Step 3

Step 3: Determine Target File
   |- specs dimension -> .ccw/specs/coding-conventions.md or architecture-constraints.md
   +- personal dimension -> ~/.ccw/personal/ or .ccw/personal/

Step 4: Validate and Write Spec
   |- Ensure target directory and file exist
   |- Check for duplicates
   |- Append rule to appropriate section
   +- Run ccw spec rebuild

Step 5: Display Confirmation
   +- If -y/--yes: Minimal output
   +- Otherwise: Full confirmation with location details
