Copilot a4f98c2490 fix(‎database/gdb):Fix panic handling in DoCommit to prevent blocking on database driver panics (#4423) ...

When underlying database drivers panic during SQL operations, the
`DoCommit` function would propagate the panic unhandled, causing Insert
operations to block indefinitely instead of returning proper errors.
This was particularly problematic with ClickHouse when using `*big.Int`
values that exceed column type limits (e.g., int128).

## Problem

The issue manifested in the following scenario:
1. User inserts data with `*big.Int` value larger than ClickHouse int128
capacity
2. ClickHouse driver panics with `"math/big: buffer too small to fit
value"`
3. Panic propagates through the call stack: `big.nat.bytes` → ClickHouse
driver → `gdb.(*Core).DoCommit`
4. Insert operation blocks indefinitely, returning neither success nor
error

## Solution

Added comprehensive panic recovery to the `DoCommit` function in
`database/gdb/gdb_core_underlying.go`:

```go
// Panic recovery to handle panics from underlying database drivers
defer func() {
    if exception := recover(); exception != nil {
        if err == nil {
            if v, ok := exception.(error); ok && gerror.HasStack(v) {
                err = v
            } else {
                err = gerror.WrapCodef(gcode.CodeDbOperationError, 
                    gerror.NewCodef(gcode.CodeInternalPanic, "%+v", exception), 
                    FormatSqlWithArgs(in.Sql, in.Args))
            }
        }
    }
}()
```

## Benefits

- **Prevents blocking**: Insert operations now return errors instead of
hanging
- **Proper error context**: Errors include full SQL statement and
arguments for debugging
- **Graceful degradation**: Applications can handle driver panics
appropriately
- **Backward compatibility**: No breaking changes to existing
functionality
- **Universal coverage**: Protects against panics from any database
driver

## Testing

Added comprehensive tests covering:
- String panic values (e.g., "math/big: buffer too small")
- Error panic values with stack traces
- Various SQL operation types (Insert, Query, Prepare, etc.)
- Error message formatting and context preservation

All existing tests continue to pass, ensuring no regressions.

Fixes #4372.
