### How did you verify your code works?
Run the code bellow and will be way harder the encounter the same
problem (I got it 1 times after 10 tries the same effect as Bun.sleep
mentioned before)
```ts
const sql = new Bun.SQL("postgres://localhost");
using conn1 = await sql.reserve();
using conn2 = await sql.reserve();
await sql`DROP TABLE IF EXISTS test1`;
await sql`CREATE TABLE IF NOT EXISTS test1 (
id INTEGER PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
uuid UUID NOT NULL
)`;
await sql`INSERT INTO test1 (uuid) VALUES (gen_random_uuid())`;
type Row = {
id: number;
uuid: string;
};
for (let i = 0; i < 100_000; i++) {
const [original]: Array<Row> = await conn1`SELECT id, uuid FROM test1 LIMIT 1`;
const [updated]: Array<Row> =
await conn1`UPDATE test1 SET uuid = gen_random_uuid() WHERE id = ${original.id} RETURNING id, uuid`;
const [retrieved]: Array<Row> = await conn2`SELECT id, uuid FROM test1 WHERE id = ${original.id}`;
if (retrieved.uuid !== updated.uuid) {
console.log("Expected retrieved and updated to match", retrieved, updated, i);
break;
}
}
```

### What does this PR do?
Fix handling BIT(1) and BIT(N) on binary protocol and text protocol, now
behavior is consistent

### What does this PR do?
- Instead of storing `len` in `BoundedArray` as a `usize`, store it as
either a `u8` or ` u16` depending on the `buffer_capacity`
- Copy-paste `BoundedArray` from the standard library into Bun's
codebase as it was removed in
https://github.com/ziglang/zig/pull/24699/files#diff-cbd8cbbc17583cb9ea5cc0f711ce0ad447b446e62ea5ddbe29274696dce89e4f
and we will probably continue using it

### What does this PR do?
Change tinyint/bool type from mysql to number instead of bool to match
mariadb and mysql2 behavior since tinyint/bool can be bigger than 1 in
mysql

Replace `catch bun.outOfMemory()`, which can accidentally catch
non-OOM-related errors, with either `bun.handleOom` or a manual `catch
|err| switch (err)`.

### What does this PR do?
optimize advance method
after this optimizations
100k req the query bellow in 1 connection takes 792ms instead of 6s
```sql
SELECT CAST(1 AS UNSIGNED) AS x
```
1mi req of the query bellow with 10 connections takes 57.41s - 62.5s
instead of 162.50s, mysql2 takes 1516.94s for comparison
```sql
SELECT * FROM users_bun_bench LIMIT 100
```

* Move `DebugThreadLock` to `bun.safety`
* Enable in `ci_assert` builds, but store stack traces only in debug
builds
* Reduce size of struct by making optional field non-optional
* Add `initLockedIfNonComptime` as a workaround for not being able to
call `initLocked` in comptime contexts
* Add `lockOrAssert` method to acquire the lock if unlocked, or else
assert that the current thread acquired the lock
* Add stack traces to `CriticalSection` and `AllocPtr` in debug builds
* Make `MimallocArena.init` infallible
* Make `MimallocArena.heap` non-nullable
* Rename `RefCount.active_counts` to `raw_count` and provide read-only
`get` method
* Add `bun.safety.alloc.assertEq` to assert that two allocators are
equal (avoiding comparison of undefined `ptr`s)

### What does this PR do?
Fix: https://github.com/oven-sh/bun/issues/21351
Relevant changes:
Fix advance to properly cleanup success and failed queries that could be
still be in the queue
Always ref before executing
Use stronger atomics for ref/deref and hasPendingActivity
Fallback when thisValue is freed/null/zero and check if vm is being
shutdown
The bug in --hot in `resolveRopeIfNeeded` Issue is not meant to be fixed
in this PR this is a fix for the postgres regression
Added assertions so this bug is easier to catch on CI

## Summary
Fixes the "index out of bounds: index 0, len 0" crash that occurs during
large batch PostgreSQL inserts, particularly on Windows systems.
The issue occurred when PostgreSQL DataRow messages contained data but
the `statement.fields` array was empty (len=0), causing crashes in
`DataCell.Putter.putImpl()`. This typically happens during large batch
operations where there may be race conditions or timing issues between
RowDescription and DataRow message processing.
## Changes
- **Add bounds checking** in `DataCell.Putter.putImpl()` before
accessing `fields` and `list` arrays
(src/sql/postgres/DataCell.zig:1043-1050)
- **Graceful degradation** - return `false` to ignore extra fields
instead of crashing
- **Debug logging** to help diagnose field metadata issues
- **Comprehensive regression tests** covering batch inserts, empty
results, and concurrent operations
## Test Plan
- [x] Added regression tests in `test/regression/issue/21311.test.ts`
- [x] Tests pass with the fix: All 3 tests pass with 212 expect() calls
- [x] Existing PostgreSQL tests still work (no regressions)
The fix prevents the crash while maintaining safe operation, allowing
PostgreSQL batch operations to continue working reliably.
## Root Cause
The crash occurred when:
1. `statement.fields` array was empty (len=0) due to timing issues
2. PostgreSQL DataRow messages contained actual data
3. Code tried to access `this.list[index]` and `this.fields[index]`
without bounds checking
This was particularly problematic on Windows during batch operations due
to potential differences in:
- Network stack message ordering
- Memory allocation behavior
- Threading/concurrency during batch operations
- Statement preparation timing
