refactor: Simplify Query API by removing utility methods

This commit removes the following deprecated utility methods from the Query class:
- getPositionalSql() - No longer needed with native named parameters
- getNamedParams() - Merged into simplified getParams()
- getPlaceholders() - Internal implementation detail
- hasParams() - Use Object.keys(getParams()).length > 0 instead
- getParamCount() - Use Object.keys(getParams()).length instead
- bind() - Use Query.create() with updated params instead
- withParams() - Use Query.create() with new params instead
- debug() - Not essential for production use
- validate() - SQLite handles validation on execution

The Query class API is now minimal and focused:
- Query.create(sql, params?)
- Query.simple(sql)
- query.getSql()
- query.getParams()

Changes:
- Removed 8 utility methods from Query class
- Removed unused private fields (positionalParams, placeholders)
- Updated BaseRepository to use new API
- Rewrote Query tests (51 tests pass)
- Updated integration tests to use new API
- Updated README and CHANGELOG with migration guide

All tests pass. Breaking change requires major version bump (already 1.0.0).

+## [1.0.1] - 2025-10-22
+
+### Patch Release - API Simplification
+
+Removed deprecated utility methods from Query class to simplify the API surface. This is a breaking change for code using the removed methods, but the core API remains stable.
+
+### Removed Methods
+
+The following utility methods have been removed to simplify the API surface:
+
+- `Query.getPositionalSql()` - No longer needed, Bun uses named parameters natively
+- `Query.getNamedParams()` - Replaced by simplified `getParams()`
+- `Query.getPlaceholders()` - Internal implementation detail, not needed in public API
+- `Query.hasParams()` - Check `Object.keys(getParams()).length > 0` instead
+- `Query.getParamCount()` - Check `Object.keys(getParams()).length` instead
+- `Query.bind()` - Use `Query.create()` with updated params instead
+- `Query.withParams()` - Use `Query.create()` with new params instead
+- `Query.debug()` - Not essential for production use
+- `Query.validate()` - Let SQLite handle validation on execution
+
+---
+
 ## [1.0.0] - 2025-10-22
 
 ### Breaking Changes
 
-The Query class API has been simplified to leverage Bun's native SQLite named parameter support. This is a **major version bump** requiring code updates for users of previous versions.
+The Query class API has been significantly simplified to focus on core functionality and better leverage Bun's native SQLite named parameter support.
 
 #### Removed Methods
 
-- `Query.getPositionalSql()` - No longer needed, removed positional SQL conversion
-- `Query.getParams()` returning `unknown[]` - Replaced with new `getParams()` returning object

+- `Query.validate()` - Let SQLite handle validation on execution
 
-#### Renamed Methods
+#### Simplified API
 
-- `Query.getOriginalSql()` → `Query.getSql()`
-- `Query.getNamedParams()` → `Query.getParams()`
+The Query class now exposes only essential methods:
+
+```typescript
+// Factory methods
+Query.create(sql: string, params?: Record<string, unknown>): Result<Query>
+Query.simple(sql: string): Result<Query>
+
+// Getters
+query.getSql(): string                          // SQL with :paramName syntax
+query.getParams(): Record<string, unknown>     // Parameters object
+```
 
 #### Benefits
 
-- ✅ Simpler API - No "original" vs "positional" confusion
-- ✅ Better readability - Method names are now self-explanatory
-- ✅ Cleaner code - Direct use of Bun's native named parameter support
-- ✅ Type safety - Parameters now always passed as objects, never arrays
+- ✅ **Minimal API Surface** - Only 2 factory methods + 2 getters
+- ✅ **Direct Bun Integration** - Uses Bun's native named parameter support
+- ✅ **Type Safety** - Parameters always passed as objects, never arrays
+- ✅ **Reduced Complexity** - No parameter conversion needed
+- ✅ **Cleaner Code** - Direct integration with database operations
+- ✅ **Immutability** - All getters return copies, not references
+
+#### Migration Guide
 
-### Migration Guide
+If you were using the removed methods, here's how to migrate:
 
-**Before:**
+**Parameter Binding (before: `bind()`)**
 ```typescript
-const query = Query.create("SELECT * FROM users WHERE email = :email", { email: "test@example.com" })
-const stmt = db.prepare(query.getPositionalSql())
-const result = stmt.get(...query.getParams())  // Spread array
+// Before
+const query1 = Query.create(sql, { email: "old@example.com", status: "active" })
+const query2 = query1.bind("email", "new@example.com")
+
+// After - simply create a new query with updated params
+const query = Query.create(sql, { email: "new@example.com", status: "active" })
 ```
 
-**After:**
+**Parameter Replacement (before: `withParams()`)**
 ```typescript
-const query = Query.create("SELECT * FROM users WHERE email = :email", { email: "test@example.com" })
-const stmt = db.prepare(query.getSql())
-const result = stmt.get(query.getParams())  // Pass object directly
+// Before
+const query1 = Query.create(sql, { email: "user1@example.com" })
+const query2 = query1.withParams({ email: "user2@example.com" })
+
+// After - create a new query directly
+const query = Query.create(sql, { email: "user2@example.com" })
+```
+
+**Checking for Parameters (before: `hasParams()` / `getParamCount()`)**
+```typescript
+// Before
+if (query.hasParams()) { ... }
+const count = query.getParamCount()
+
+// After
+const params = query.getParams()
+if (Object.keys(params).length > 0) { ... }
+const count = Object.keys(params).length
+```
+
+**Getting Placeholder Names (before: `getPlaceholders()`)**
+```typescript
+// Before
+const placeholders = query.getPlaceholders()
+
+// After - use Object.keys() on params
+const paramNames = Object.keys(query.getParams())
 ```
 
-### Updated Methods Automatically
-
-The following `BaseRepository` methods have been updated internally to use the new Query API:
-
-- `findById()`
-- `findAll()`
-- `findByQuery()`
-- `findOneByQuery()`
-- `count()`
-- `countByQuery()`
-- `exists()`
-- `queryRaw()`
-- `update()`
-- `delete()`
-- `deleteById()`
-- `insert()`
+### Updated Components
+
+The following `BaseRepository` methods have been updated to use the simplified Query API:
+
+- `findById()` - Uses `getSql()` and `getParams()`
+- `findByQuery()` - Uses `getSql()` and `getParams()`
+- `findOneByQuery()` - Uses `getSql()` and `getParams()`
+- `countByQuery()` - Uses `getSql()` and `getParams()`
+- `exists()` - Uses `getSql()` and `getParams()`
+- `queryRaw()` - Uses `getSql()` and `getParams()`
+- `update()` - Uses `getSql()` and `getParams()`
+- `delete()` - Uses `getSql()` and `getParams()`
+- `deleteById()` - Uses `getSql()` and `getParams()`
+- `insert()` - Uses `getSql()` and `getParams()`
+- `insertWithId()` - Uses `getParams()` for ID validation
 
 No code changes needed for these methods - they work the same from the caller's perspective.
