fix: add sort and limit to /my command for consistency with /bounty

- Add same sort_key logic as /bounty (due date first, then created_at)
- Add default limit of 5 with "Showing X of Y" message
- Add "all" flag to show expired bounties
- Add delete button for consistency with /bounty

Fixes #94

+# Part I: Repository Audit
+
+## 1.1 Current Architecture
+
+JIGAIDO follows **hexagonal architecture** with clear separation:

+
+## 1.3 Bugs & Issues Found
+
+### Bug 1: Admin Promotion Logic Edge Case
+**Location**: `core/services.py` - `add_admin()`
+
+**Issue**: The first admin can self-promote, but if the Telegram group creator joins later, they won't be recognized as admin since they're not in `admin_usernames`.
+
+**Code**:
+```python
+# core/services.py:44-49
+has_no_admins = room_data is None or not room_data.admin_usernames
+is_self_promotion = requesting_username == username
+
+if not self.is_admin(room_id, requesting_username):
+    if not (has_no_admins and is_self_promotion):
+        raise PermissionError("Only admins can add admins.")
+```
+
+**Recommendation**: Document this behavior or enhance to auto-detect Telegram group creator.
+
+---
+
+### Bug 2: Hard Delete Method in Storage
+**Location**: `adapters/storage/json_file.py:113-119`
+
+**Issue**: `delete_bounty()` in storage does hard delete, while `BountyService.delete_bounty()` does soft delete. The storage method is unused but confusing.
+
+**Code**:
+```python
+def delete_bounty(self, room_id: int, bounty_id: int) -> None:
+    """Delete a bounty from a room."""
+    room_data = self.load(room_id)
+    if room_data is None:
+        return
+    room_data.bounties = [b for b in room_data.bounties if b.id != bounty_id]
+    self.save(room_data)
+```
+
+**Recommendation**: Remove or mark as deprecated.
+
+---
+
+### Issue 3: Spec vs Code Inconsistency
+**Location**: `SPEC.md` vs `commands.py`
+
+**Issue**: SPEC.md says anyone can `/add` in groups, but code requires admin.
+
+| Command | SPEC.md | Code |
+|---------|---------|------|
+| `/add` | anyone | admin only |
+| `/edit` | creator only | admin only |
+| `/delete` | creator only | admin only |
+
+**Recommendation**: Update SPEC.md to reflect actual implementation.
+
+---
+
+### Issue 4: No Input Sanitization
+**Location**: `commands.py` - `parse_args()`
+
+**Issue**: Links without proper scheme (e.g., `github.com/user/repo`) are accepted as-is.
+
+**Recommendation**: Consider normalizing URL scheme or validating format.
+
+---
+
+### Issue 5: No Rate Limiting
+**Location**: `/add` command
+
+**Issue**: No limit on:
+- Number of bounties per room
+- Text length
+- Request rate
+
+**Recommendation**: Add rate limiting for production use.
+
+---
+
+## 1.4 Test Status
+
+```bash
+$ PYTHONPATH=. python -m pytest tests/
+======================== 98 passed, 1 warning ========================
+```
+
+**Note**: Tests require `PYTHONPATH=.` to run. Consider adding `pytest.ini` or `pyproject.toml`.
+
+---
+
+# Part II: Category Feature Specification
+
+## 2.1 Overview
+
+Add category support to JIGAIDO to allow filtering and organizing bounties.
+
+**Goals**:
+- Admin-only category management (create, delete)
+- Multiple categories per bounty (no duplicates)
+- Filter bounties by category
+- Show categories on `/show` command
+- Backward compatibility (existing bounties work without categories)
+
+## 2.2 Data Model
+
+### Category
+```python
+@dataclass
+class Category:
+    """A category for organizing bounties in a room."""
+    id: str           # slug: lowercase alphabetic only, e.g., "bug", "feature"
+    name: str         # display name: e.g., "Bug", "Feature"
+    created_at: int
+    deleted_at: int | None = None  # soft delete
+```
+
+**Constraints**:
+- `id` (slug): lowercase alphabetic only, no symbols, e.g., `^[a-z]+$`
+- `name`: human-readable display
+- Unique within room (slug must be unique)
+- Soft delete preserves data
+
+### Bounty (Modified)
+```python
+@dataclass
+class Bounty:
+    # ... existing fields ...
+    id: int
+    text: str | None
+    link: str | None
+    due_date_ts: int | None
+    created_at: int
+    created_by_user_id: int
+    deleted_at: int | None = None
+    created_by_username: str | None = None
+    category_ids: list[str] = field(default_factory=list)  # NEW
+```
+
+### RoomData (Modified)
+```python
+@dataclass
+class RoomData:
+    room_id: int
+    bounties: list[Bounty]
+    next_id: int
+    timezone: str | None = None
+    admin_usernames: list[str] | None = None
+    categories: list[Category] = field(default_factory=list)  # NEW
+```
+
+## 2.3 Category Scope
+
+- **Per room**: Same as bounties, each room (group/DM) has independent categories
+- **Admin only**: Only admins can create/delete categories
+- **User access**: Regular users can only filter by category
+
+## 2.4 Service Layer API
+
+All methods require admin permission unless specified otherwise.
+
+### Category Management
+
+```python
+class BountyService:
+    # ... existing methods ...

+
+### Bounty Listing with Category Filter
+
+```python
+    def list_bounties(
+        self,
+        room_id: int,
+        category_slugs: list[str] | None = None,
+        include_expired: bool = False
+    ) -> list[Bounty]:
+        """List bounties with optional category filtering.
+
+        Args:
+            room_id: Room identifier
+            category_slugs: If provided, filter by ANY of these categories (OR)
+            include_expired: If True, include bounties past due date
+
+        Returns:
+            List of non-deleted bounties, sorted by due date
+        """
+        ...
+```
+
+## 2.5 Filtering Logic
+
+- **Single category**: `/bounty -c bug` → bounties with "bug"
+- **Multiple categories (OR)**: `/bounty -c bug,feature` → bounties with "bug" OR "feature"
+- **No filter**: `/bounty` → all bounties (current behavior)
+
+## 2.6 Command Syntax
+
+### Category Management
+```
+/category                      - list categories
+/category add <slug> <name>    - create category (admin)
+/category delete <slug>        - soft delete category (admin)
+```
+
+### Bounty with Category
+```
+/add <text> [link] [date] -cat <slug>     - add with category
+/add <text> [link] [date] -cat <slug1>,<slug2> - add with multiple categories
+
+/update <id> -cat <slug>        - add category to bounty
+/update <id> -cat <slug1>,<slug2> - set categories (replace all)
+/update <id> -cat -             - clear all categories
+/update <id> -remove-cat <slug> - remove specific category
+```
+
+### Bounty Listing with Filter
+```
+/bounty                        - all bounties (current)
+/bounty -c <slug>              - filter by category
+/bounty -c <slug1>,<slug2>    - filter by multiple categories (OR)
+/bounty all                    - show expired (current)
+/bounty all -c <slug>          - show expired + filter by category
+```
+
+### Show Bounty
+```
+/show <id>                     - show bounty details with categories
+```
+
+## 2.7 Display Format
+
+### `/category` output
+```
+Categories:
+- bug → Bug Report
+- feature → Feature Request
+- docs → Documentation
+```
+
+### `/show <id>` output (with categories)
+```
+[#1] Fix login bug
+🔗 https://github.com/...
+📅 15 April 2026 14:30 (Asia/Jakarta)
+📂 Categories: bug | feature
+👤 @username
+📌 Created: 2026-04-01 10:00
+```
+
+### `/bounty -c bug` output
+```
+Filtering with 🐛 bug category:
+Showing 3 of 10 bounties:
+[#5] ...
+[#1] ...
+[#3] ...
+```
+
+### `/bounty -c bug,feature` output
+```
+Filtering with 🐛 bug, ✨ feature categories:
+Showing 5 of 10 bounties:
+[#5] ...
+[#1] ...
+```
+
+## 2.8 Edge Cases
+
+| Scenario | Behavior |
+|----------|----------|
+| Delete category | Soft delete - existing bounties keep category in data, but filter won't find it |
+| Filter by deleted category | Show "No bounties with this category" or error |
+| Add duplicate category to bounty | No-op, return False |
+| Add invalid slug (uppercase/symbols) | Reject with validation error |
+| Category slug conflict | Reject with "Category already exists" |
+| Bounty without categories | `category_ids = []` (backward compatible) |
+
+## 2.9 Test Cases to Add

+
+# Part IV: Open Questions
+
+1. **Category icon/emoji**: Should categories have optional emoji? (Not in initial spec, can add later)
+2. **Category reactivation**: Should soft-deleted categories be reactable? (Not in initial spec)
+3. **Bulk category operations**: Should we support `/category add bulk`? (Not in initial spec)
