## Summary
- Fix off-by-one error in `preprocessUpdateRequests` where the bounds
check used `>` instead of `>=` when validating package IDs from the
resolution buffer
- When `old_resolution == packages.len`, the check `> packages.len`
passes but `resolutions_of_yore[old_resolution]` is out of bounds since
valid indices are `0` to `packages.len-1`
- This causes an internal assertion failure during `bun install` with
update requests
## The Bug
```zig
// BEFORE (buggy) - at lockfile.zig:484 and :522
if (old_resolution > old.packages.len) continue;
const res = resolutions_of_yore[old_resolution]; // OOB when old_resolution == packages.len
// AFTER (fixed)
if (old_resolution >= old.packages.len) continue;
const res = resolutions_of_yore[old_resolution]; // Now safe
```
