Subject: [PATCH] Fix Latexify deprecation warnings in ODEProblemLibrary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit fixes deprecation warnings that occur when running tests with
`--depwarn=error` by updating all `latexify()` calls to use the new
`mult_symbol=""` parameter instead of the deprecated `cdot=false`.

## Issue Fixed
- **Latexify deprecation**: Changed from deprecated `cdot=false` to `mult_symbol=""`
- Affected 9 `latexify()` calls in `strange_attractors.jl` documentation strings

## Error Message
```
ERROR: Latexify received the deprecated keyword argument cdot = false and
converted it to mult_symbol = "". Pass the latter directly to remove this warning.
```

## Changes Made
- Updated all `$(latexify(system))` calls to `$(latexify(system; mult_symbol=""))`
- Fixed calls for: thomas, lorenz, aizawa, dadras, chen, rossler,
  rabinovich_fabrikant, sprott, and hindmarsh_rose attractors

## Verification
- ODEProblemLibrary tests now pass with `--depwarn=error`
- All strange attractor documentation maintains proper LaTeX formatting
- No functional changes to the mathematical representations
