I think it is mostly correct, not so sure how to handle `BLOB`. One
thing that caught my attention is that sqlite seems to have a
optimization for trivial cases, saving some bytecodes, for instance:
I'm looking that right now.

Closes#767
## The purpose of this PR
- Do not create a new `io` and instead use `io` which is used when
creating `LimboDatabase`.
- Run the loop of `step` function on the rust side(better for
performance as we don't have to switch between java <-> rust)
## Changes
- Java
- handle invalid cases
- remove @Disabled annotation from tests
- Rust
- add loops in the step function
## Reference
- https://github.com/tursodatabase/limbo/issues/615Closes#761
Take the logical OR of the values in register P1 and P2 and store the answer in register P3. If either P1 or P2 is nonzero (true) then the result is 1 (true) even if the other input is NULL. A NULL and false or two NULLs give a NULL output.
Take the logical AND of the values in registers P1 and P2 and write the result into register P3. If either P1 or P2 is 0 (false) then the result is 0 even if the other input is NULL. A NULL and true or two NULLs give a NULL output.
## What?
- centralized Rust integration and regression tests
- no new tests added
- no tests removed
- only refactored tests into modules and common utils
## Why?
- @penberg and I have a discussion [here](https://github.com/tursodataba
se/limbo/pull/694#discussion_r1921949665) about centralizing the
integration/ regression tests so that they are not scattered around.
- this is a PR to do that and some refactor of the existing tests to
make the structure easier to navigate + add new tests in the future.

What? adding PRAGMA statements in COMPAT doc.
Why?
- each pragma is quite independent of each other.
- make it clear for contribution.
- maybe lower the bar of contributing.

Change explanation is in the code comment for `Insn::Eq`:
```
/// Jump if either of the operands is null. Used for "jump when false" logic.
/// Eg. "SELECT * FROM users WHERE id = NULL" becomes:
/// <JUMP TO NEXT ROW IF id != NULL>
/// Without the jump_if_null flag it would not jump because the logical comparison "id != NULL" is never true.
/// This flag indicates that if either is null we should still jump.
jump_if_null: bool,
```
Closes#754
Excerpt from SQLite bytecode documentation for e.g. `Lt`:
> If the SQLITE_JUMPIFNULL bit of P5 is set and either reg(P1) or
reg(P3) is NULL then the take the jump. If the SQLITE_JUMPIFNULL bit is
clear then fall through if either operand is NULL.
I didn't want to start putting these flags into a bitmask so I just
added a separate boolean. Probably for sqlite `EXPLAIN` compatibility we
should, IF we want to be exactly compatible (which we aren't anyway atm)
Closes#755
Currently, we are using the same `Parser` instance across multiple
queries (9cc9577c91). But during this
error the parser is not finalized, so parser stack is not reset, thereby
triggering the assertion at https://github.com/tursodatabase/limbo/blob/
15f7928551435458e2991dde3a76ce71e8a32057/vendored/sqlite3-
parser/third_party/lemon/lempar.rs#L663
This PR fixes the panic by calling `sqlite3ParserFinalize()` in the case
of error.
