05d0475c6c Update to zig 0.15.2 (#24204) 
Fixes ENG-21287

Build times, from `bun run build && echo '//' >> src/main.zig && time
bun run build`

|Platform|0.14.1|0.15.2|Speedup|
|-|-|-|-|
|macos debug asan|126.90s|106.27s|1.19x|
|macos debug noasan|60.62s|50.85s|1.19x|
|linux debug asan|292.77s|241.45s|1.21x|
|linux debug noasan|146.58s|130.94s|1.12x|
|linux debug use_llvm=false|n/a|78.27s|1.87x|
|windows debug asan|177.13s|142.55s|1.24x|

Runtime performance:

- next build memory usage may have gone up by 5%. Otherwise seems the
same. Some code with writers may have gotten slower, especially one
instance of a counting writer and a few instances of unbuffered writers
that now have vtable overhead.
- File size reduced by 800kb (from 100.2mb to 99.4mb)

Improvements:

- `@export` hack is no longer needed for watch
- native x86_64 backend for linux builds faster. to use it, set use_llvm
false and no_link_obj false. also set `ASAN_OPTIONS=detect_leaks=0`
otherwise it will spam the output with tens of thousands of lines of
debug info errors. may need to use the zig lldb fork for debugging.
- zig test-obj, which we will be able to use for zig unit tests

Still an issue:

- false 'dependency loop' errors remain in watch mode
- watch mode crashes observed

Follow-up:

- [ ] search `comptime Writer: type` and `comptime W: type` and remove
- [ ] remove format_mode in our zig fork
- [ ] remove deprecated.zig autoFormatLabelFallback
- [ ] remove deprecated.zig autoFormatLabel
- [ ] remove deprecated.BufferedWriter and BufferedReader
- [ ] remove override_no_export_cpp_apis as it is no longer needed
- [ ] css Parser(W) -> Parser, and remove all the comptime writer: type
params
- [ ] remove deprecated writer fully

069a8d0b5d patch: make Header struct use one-based line indexing by default (#21995) 
### What does this PR do?

- Change Header struct start fields to default to 1 instead of 0
- Rename Header.zeroes to Header.empty with proper initialization
- Maintain @max(1, ...) validation in parsing to ensure one-based
indexing
- Preserve compatibility with existing patch file formats

9907c2e9fa fix(patch): add bounds checking to prevent segfault during patch application (#21939) 
## Summary

- Fixes segmentation fault when applying patches with out-of-bounds line
numbers
- Adds comprehensive bounds checking in patch application logic
- Includes regression tests to prevent future issues

## Problem

Previously, malformed patches with line numbers beyond file bounds could
cause segmentation faults by attempting to access memory beyond
allocated array bounds in `addManyAt()` and `replaceRange()` calls.

## Solution

Added bounds validation at four key points in `src/patch.zig`:

1. **Hunk start position validation** (line 283-286) - Ensures hunk
starts within file bounds
2. **Context line validation** (line 294-297) - Validates context lines
exist within bounds
3. **Insertion position validation** (line 302-305) - Checks insertion
position is valid
4. **Deletion range validation** (line 317-320) - Ensures deletion range
is within bounds

All bounds violations now return `EINVAL` error gracefully instead of
crashing.

## Test Coverage

Added comprehensive regression tests in
`test/regression/issue/patch-bounds-check.test.ts`:

- ✅ Out-of-bounds insertion attempts
- ✅ Out-of-bounds deletion attempts  
- ✅ Out-of-bounds context line validation
- ✅ Valid patch application (positive test case)

Tests verify that `bun install` completes gracefully when encountering
malformed patches, with no crashes or memory corruption.

## Test Results

```
bun test v1.2.21
✅ Bounds checking working: bun install completed gracefully despite malformed patch
✅ Bounds checking working: bun install completed gracefully despite deletion beyond bounds
✅ Bounds checking working: bun install completed gracefully despite context lines beyond bounds

 4 pass
 0 fail
 22 expect() calls
Ran 4 tests across 1 file. [4.70s]
```

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)`.
