2eebcee522 Fix DevServer HMR sourcemap offset issues (#22739) 
## 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

437e15bae5 Replace catch bun.outOfMemory() with safer alternatives (#22141) 
Replace `catch bun.outOfMemory()`, which can accidentally catch
non-OOM-related errors, with either `bun.handleOom` or a manual `catch
|err| switch (err)`.

2ed5b0ffad Switch to bun.Ordinal for LineColumnOffset (#21658) 
### 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.
