Migrate MySQL parser from tidb to sqlc-dev/marino (#4414)

* Migrate MySQL parser from tidb to sqlc-dev/marino

Marino is a sqlc-maintained hard fork of pingcap/parser with a flatter
package layout. The previous test_driver concrete types (ValueExpr,
ParamMarkerExpr) are merged into the ast package as ValueExprBase and
ParamMarkerExprBase.

- Swap github.com/pingcap/tidb/pkg/parser for github.com/sqlc-dev/marino
- Drop pingcap/uber/lumberjack transitive deps no longer needed
- Update dolphin imports to marino's flatter layout (no pkg/parser/...)
- Replace driver.ValueExpr/ParamMarkerExpr type assertions with
  pcast.ValueExprBase/ParamMarkerExprBase
- Replace n.TexprNode.Type with promoted n.Type (marino's exprNode is
  unexported, but Type is promoted via field embedding)

* Pin sqlc-dev/marino to v0.1.0

 # Dolphin Engine (MySQL) - Claude Code Guide
 
-The dolphin engine handles MySQL parsing and AST conversion using the TiDB parser.
+The dolphin engine handles MySQL parsing and AST conversion using the Marino parser
+(a sqlc-maintained fork of the TiDB / pingcap parser).
 
 ## Architecture
 
 ### Parser Flow
 ```
-SQL String → TiDB Parser → TiDB AST → sqlc AST → Analysis/Codegen
+SQL String → Marino Parser → Marino AST → sqlc AST → Analysis/Codegen
 ```
 
 ### Key Files
-- `convert.go` - Converts TiDB AST nodes to sqlc AST nodes
+- `convert.go` - Converts Marino AST nodes to sqlc AST nodes
 - `format.go` - MySQL-specific formatting (identifiers, types, parameters)
 - `parse.go` - Entry point for parsing MySQL SQL
 
-## TiDB Parser
+## Marino Parser
 
-The TiDB parser (`github.com/pingcap/tidb/pkg/parser`) is used for MySQL parsing:
+The Marino parser (`github.com/sqlc-dev/marino`) is used for MySQL parsing. It is a
+hard fork of `github.com/pingcap/tidb/pkg/parser` with a flatter package layout
+(no `pkg/parser/...` prefix) and the former `test_driver` types merged into the
+`ast` package as `ValueExprBase` / `ParamMarkerExprBase`.
 
 ```go
 import (
-    pcast "github.com/pingcap/tidb/pkg/parser/ast"
-    "github.com/pingcap/tidb/pkg/parser/mysql"
-    "github.com/pingcap/tidb/pkg/parser/types"
+    pcast "github.com/sqlc-dev/marino/ast"
+    "github.com/sqlc-dev/marino/mysql"
+    "github.com/sqlc-dev/marino/types"
 )
 ```
 
-### Common TiDB Types
+### Common Marino Types
 - `pcast.SelectStmt`, `pcast.InsertStmt`, etc. - Statement types
 - `pcast.ColumnNameExpr` - Column reference
 - `pcast.FuncCallExpr` - Function call
