## Summary
This PR refactors the sourcemap module by extracting large structs from
`src/sourcemap/sourcemap.zig` into their own dedicated files, improving
code organization and maintainability.
## Changes
- **Extracted `ParsedSourceMap` struct** to
`src/sourcemap/ParsedSourceMap.zig`
- Made `SourceContentPtr` and related methods public
- Made `standaloneModuleGraphData` public for external access
- **Extracted `Chunk` struct** to `src/sourcemap/Chunk.zig`
- Added import for `appendMappingToBuffer` from parent module
- Includes all nested types: `VLQSourceMap`, `NewBuilder`, `Builder`
- **Extracted `Mapping` struct** to `src/sourcemap/Mapping.zig`
- Added necessary imports: `assert`, `ParseResult`, `debug`
- Includes nested types: `MappingWithoutName`, `List`, `Lookup`
- **Updated `src/sourcemap/sourcemap.zig`**
- Replaced struct definitions with imports:
`@import("./StructName.zig")`
- Maintained all public APIs
All structs now follow the `const StructName = @This()` pattern for
top-level declarations.
## Testing
- ✅ Compiled successfully with `bun bd`
- ✅ All existing functionality preserved
- ✅ No API changes - fully backwards compatible
## Before
- Single 2000+ line file with multiple large structs
- Difficult to navigate and maintain
## After
- Modular structure with separate files for each major struct
- Easier to find and modify specific functionality
- Better code organization

### What does this PR do?
Fixes a crash related to the dev server overwriting the uws user context
pointer when setting abort callback.
Adds support for `return new Response(<jsx />, { ... })` and `return
Response.render(...)` and `return Response.redirect(...)`:
- Created a `SSRResponse` class to handle this (see
`JSBakeResponse.{h,cpp}`)
- `SSRResponse` is designed to "fake" being a React component
- This is done in JSBakeResponse::create inside of
src/bun.js/bindings/JSBakeResponse.cpp
- And `src/js/builtins/BakeSSRResponse.ts` defines a `wrapComponent`
function which wraps
the passed in component (when doing `new Response(<jsx />, ...)`). It
does
this to throw an error (in redirect()/render() case) or return the
component.
- Created a `BakeAdditionsToGlobal` struct which contains some
properties
needed for this
- Added some of the properties we need to fake to BunBuiltinNames.h
(e.g.
`$$typeof`), the rationale behind this is that we couldn't use
`structure->addPropertyTransition` because JSBakeResponse is not a final
JSObject.
- When bake and server-side, bundler rewrites `Response ->
Bun.SSRResponse` (see `src/ast/P.zig` and `src/ast/visitExpr.zig`)
- Created a new WebCore body variant (`Render: struct { path: []const u8
}`)
- Created when `return Response.render(...)`
- When handled, it re-invokes dev server to render the new path
Enables server-side sourcemaps for the dev server:
- New source providers for server-side:
(`DevServerSourceProvider.{h,cpp}`)
- IncrementalGraph and SourceMapStore are updated to support this
There are numerous other stuff:
- allow `app` configuration from Bun.serve(...)
- fix errors stopping dev server
- fix use after free related to in
RequestContext.finishRunningErrorHandler
- Request.cookies
- Make `"use client";` components work
- Fix some bugs using `require(...)` in dev server
- Fix catch-all routes not working in the dev server
- Updates `findSourceMappingURL(...)` to use `std.mem.lastIndexOf(...)`
because
the sourcemap that should be used is the last one anyway

## Summary
Fixes sourcemap offset issues in DevServer HMR mode that were causing
incorrect line number mappings when debugging.
## Problem
When using DevServer with HMR enabled, sourcemap line numbers were
consistently off by one or more lines when shown in Chrome DevTools. In
some cases, they were off when shown in the terminal as well.
## Solution
### 1. Remove magic +2 offset
Removed an arbitrary "+2" that was added to `runtime.line_count` in
SourceMapStore.zig. The comment said "magic fairy in my dreams said it
would align the source maps" - this was causing positions to be
incorrectly offset.
### 2. Fix double-increment bug
ErrorReportRequest.zig was incorrectly adding 1 to line numbers that
were already 1-based from the browser, causing an off-by-one error.
### 3. Improve type safety
Converted all line/column handling to use `bun.Ordinal` type instead of
raw `i32`, ensuring consistent 0-based vs 1-based conversions throughout
the codebase.
## Test plan
- [x] Added comprehensive sourcemap tests for complex error scenarios
- [x] Tested with React applications in dev mode
- [x] Verified line numbers match correctly in browser dev tools
- [x] Existing sourcemap tests continue to pass

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?
It is easy to confuse `lines` and `columns` fields in `LineColumnOffset`
struct inside of `src/sourcemap/sourcemap.zig` as being either one or
zero based. The sourcemap spec says line and column offsets are zero
based. There was a place that was incorrectly assuming it was one based.
This PR switches it to use `bun.Ordinal` instead of bare `u32` integers
to prevent bugs and from this happening again.
