i couldn't really write a test for this, as it only happens when codegen + minifier are used together.

Regression should be prevented by the 262 suite in #8256 (failed CI run before i implemented this fix: https://github.com/oxc-project/oxc/actions/runs/12621310419/job/35168016825)

fix(codegen): source map builder panicked because it attempted to subtract with overflow in search_original_line_and_column (#8185)
See:
https://github.com/oxc-project/monitor-oxc/actions/runs/12531534720/job/34949348092
Related: #7926 

This line causes panic.

46fc1a8b7d/crates/oxc_codegen/src/sourcemap_builder.rs (L147-L148)

After investigation, I found that the root cause was the code removed
in this PR. I don’t understand what the code was used for, but it was
obviously wrong. Because `idx` is always smaller than `cap`

perf(sourcemap): improve perf of search_original_line_and_column (#7926)
this seems to show a decent speed up on perf.
the thinking behind this change is:
1. subsequent calls to `search_original_line_and_column` will **never**
look at back at lines it has already searched
2. binary search is faster in this case as typically `idx` is only
increased by a small amount

Given this, we can skip checking a bunch of lines (that will never
return true) improving performance.

This is a very hot path.

850dd43597 fix(codegen): missing , when generating type parameters with jsx (#7929)

3858221f45 refactor(global): sort imports (#7883)
Pure refactor. Re-order imports for clarity:

1. `std`
2. External crates
3. `oxc_*` crates
4. Current crate `use crate::...`
5. Super `use super::...`
6. Local modules

This order is from "furthest away" to "closest". This makes it clearer to see what is coming from where.

`cargo +nightly fmt` (#7877) did a lot of the work, but unfortunately `rustfmt` does not have an option to (a) put workspace crates in a separate block from external crates and (b) move `mod` statements to after `use` statements.
