$(cat <<'EOF' refactor: revert franc, improve code quality, and cleanup unused files

- Revert language detection from franc back to lande
- Add label deduplication checks in moderation functions
- Improve type safety with explicit type assertions
- Simplify check iteration logic across handle/post/profile checks
- Remove unused monitor.ts and processJetstream.ts files
- Remove test files and vitest config
- Remove temporary PLAN.md and PRD.md files
- Add duration support for post labels
- Fix import ordering and formatting issues
- Add modTool metadata to moderation events

-# Implementation Plan: Replace lande with franc
-
-## Overview
-Replace the `lande` library with `franc` for language detection in the `getLanguage` function located in `src/utils.ts`.
-
-## Current State Analysis
-- **Current Library**: `lande` v1.0.10
-- **Function Location**: `src/utils.ts:67-92`
-- **Current Implementation**:
-  - Uses dynamic import: `const lande = (await import("lande")).default;`
-  - Returns a probability map sorted by likelihood
-  - Returns the language code with highest probability
-  - Defaults to "eng" for empty or invalid input
-
-## Implementation Steps
-
-### 1. Research & Dependencies
-- **franc** is a natural language detection library similar to `lande`
-- Supports 187 languages (ISO 639-3 codes)
-- Smaller footprint and better maintained than `lande`
-- Returns ISO 639-3 codes (3-letter codes like "eng", "fra", "spa")
-
-### 2. Code Changes Required
-
-#### Step 2.1: Update package.json
-- Remove: `"lande": "^1.0.10"`
-- Add: `"franc": "^6.2.0"` (latest stable version)
-
-#### Step 2.2: Modify getLanguage function
-```typescript
-// Before (lines 82-92)
-const lande = (await import("lande")).default;
-let langsProbabilityMap = lande(profileText);
-langsProbabilityMap.sort(...);
-return langsProbabilityMap[0][0];
-
-// After
-const { franc } = await import("franc");
-const detectedLang = franc(profileText);
-return detectedLang === "und" ? "eng" : detectedLang;
-```
-
-### 3. Key Differences & Considerations
-
-#### API Differences:
-- **lande**: Returns array of `[language, probability]` tuples
-- **franc**: Returns single language code or "und" (undetermined)
-
-#### Return Values:
-- Both libraries use ISO 639-3 codes (3-letter codes)
-- franc returns "und" for undetermined text (we'll map to "eng" default)
-
-### 4. Testing Strategy
-1. Test with empty string → should return "eng"
-2. Test with invalid input (null/undefined) → should return "eng"
-3. Test with English text → should return "eng"
-4. Test with other language samples → verify correct detection
-5. Test with mixed language text → verify reasonable detection
-
-### 5. Rollback Plan
-If issues arise:
-1. Keep the original `lande` code commented
-2. Can quickly revert by uncommenting old code and reinstalling `lande`
-
-## Implementation Order
-1. ✅ Analyze current implementation
-2. ✅ Research franc library compatibility
-3. 📝 Create this implementation plan
-4. Update package.json to replace lande with franc
-5. Modify getLanguage function in src/utils.ts
-6. Run lint and format checks
-7. Test the changes manually or with existing tests
-
-## Risk Assessment
-- **Low Risk**: Direct replacement with similar functionality
-- **Compatibility**: Both libraries use ISO 639-3 codes
-- **Performance**: franc is generally faster and lighter
-- **Maintenance**: franc is more actively maintained

 # How to build checks for skywatch-automod
 
 ## Introduction
-
 Constants.ts defines three types of types of checks: `HANDLE_CHECKS`, `POST_CHECKS`, and `PROFILE_CHECKS`.
 
 For each check, users need to define a set of regular expressions that will be used to match against the content of the post, handle, or profile. A maximal example of a check is as follows:
···
 ```typescript
 export const HANDLE_CHECKS: Checks[] = [
   {
-    language: "[eng]", // Language of the check. If the check language does not match the content language, the check will be skipped. Assign null or remove field to apply to all languages.
     label: "example",
     comment: "Example found in handle",
     description: true, // Optional, only used in handle checks
     displayName: true, // Optional, only used in handle checks
-    reportAcct: false, // if true, the check will only report the content against the account, not label.
