v0.1.8 — Lint explainers, typo correction, friendlier toggle help

Three UX improvements that make the CLI more discoverable when you don't quite remember the right name or rule.

✨ New

• beacon lint --explain <rule> — verbose docs for any of the 11 lint rules: severity, why the rule exists, allowed patterns, example violations (bad → good), and how to fix.

  beacon lint --explain                  # list all rules grouped by severity
  beacon lint --explain kebab-case       # explain a specific rule

• Typo correction for unknown commands and add-ons — Levenshtein-based "did you mean?" suggestions (max 3 edits).

  $ beacon linnt
  ✗ Error: Unknown command "linnt".
    → Did you mean lint?
  
  $ beacon enable opperations
  ✗ Error: Unknown add-on category: "opperations". Did you mean "operations"?

• beacon enable / beacon disable with no add-on — now print the list of available add-on categories with one-line descriptions instead of cac's terse missing required arg error.

🧰 Internal

• New module src/ui/suggest.ts (classic Levenshtein DP + closestMatch helper) reused by both the lint --explain typo handler and the enable/disable validator.
• 13 new unit tests for suggest.ts. Test suite now at 180 passing across 30 files.
