b519509349 core/io: Add internal in-memory MemoryIO to all IO layers 
Honestly I don't have 100% sure if this is a good idea, the reasoning is that in any IO we'll want to do memory only operations like creating tables etc, so may want a common way to access it

fc50609491 Fix io_uring WAL write corruption by ensuring buffer lifetime 
Ensure the Arc<RefCell<Buffer>> in UringFile::pwrite remains alive until
the io_uring write completes by referencing it in the completion callback.
This prevents WAL file corruption where the correct buffer data was
overwritten with stale memory (e.g., 00 18 27 xx instead of 37 7f 06 82).

Validation:
- Tested with limbo -v io_uring and WAL operations.
- Verified with xxd and wal-browser.

01671d1d1e Merge 'Performance improvements for Unix I/O backend' from Preston Thorpe 
This PR reworks the unix I/O backend, removing runtime reference
counting/borrow checking and optimizing away the hashmap in favor of a
static array, with an unlikely fallback vec.
The only reason the fallback vec is there is because unlike the
`io_uring` module, we cannot simply index into the array with the fd  as
the OS could theoretically give us a fd up to I believe 1024 so keeping
an array of that size for a few elements is unnecessary.

Closes #940

0638550be7 Merge 'Remove unnecessary reference counting from completion I/O callbacks' from Preston Thorpe 
I am on a bit of a mission to revisit a lot of the ref counting, this
was an easy first win.
It seems to be a linear path of function calls or hashmaps which can own
the completions directly, no cloning needed.
