fn-23-zgk.1 Add slugify and update epic creation

Description

Add a stdlib-only slugify() function and integrate it into epic creation.

Size: M Files: plugins/flow-next/scripts/flowctl.py

Approach

1. Add slugify() function after line 582 (after generate_epic_suffix):

   • Use Django pattern (unicodedata + re, no deps)
   • Max 40 chars (leaves room for fn-XXX- prefix in 63 char limit)
   • Return None if result is empty (for fallback)

2. Update cmd_epic_create() at line 2664-2665:

   • Call slugify(args.title)
   • Fallback to generate_epic_suffix() if slugify returns None/empty
   • Keep existing random suffix as fallback for edge cases

Key context

Django's slugify pattern (no external deps):

import re, unicodedata
text = unicodedata.normalize("NFKD", text).encode("ascii", "ignore").decode("ascii")
text = re.sub(r"[^\w\s-]", "", text.lower())
text = re.sub(r"[-\s]+", "-", text).strip("-_")

Edge cases requiring fallback to random:

• Empty title: --title ""
• Only special chars: --title "!@#$"
• Unicode-only: --title "中文" (with ascii encoding)

Acceptance

• slugify("Add OAuth Login") returns "add-oauth-login"
• slugify("Fix bug #123!") returns "fix-bug-123"
• slugify("Multiple spaces") returns "multiple-spaces"
• slugify("") returns None (empty)
• slugify("!@#$%") returns None (no alphanumeric)
• Long titles truncate at word boundary within 40 chars
• flowctl epic create --title "Add OAuth" produces fn-N-add-oauth
• flowctl epic create --title "" falls back to 3-char random
• Existing tests still pass

Done summary

Added slugify() function using Django pattern (stdlib only) and updated epic creation to use slugified titles as suffixes with random fallback. Updated regex patterns in both plugin and vendored copies for parity.
