Standardize naming conventions (#12)

## Summary

Standardize naming conventions across the entire wizapp-stdlib codebase by replacing inconsistent prefixes and snake_case with a unified `wp` prefix + CamelCase scheme.

## Changes

### Naming convention applied

| Pattern | Before | After |
|---|---|---|
| Public functions | `wapp_module_function` | `wpModuleFunction` |
| Public types | `GenericXxx`, bare `Xxx` | `WpXxx` |
| Constants / enum values | `WAPP_XXX`, `SHELL_XXX` | `WP_XXX`, `WP_SHELL_XXX` |
| Internal functions | `_module_function` | `_moduleFunction` |
| Storage-class macros | `wapp_extern`, `wapp_intern` | `wp_extern`, `wp_intern` |

### Modules affected

All 20 modules were renamed: `arena`, `array`, `dbl_list`, `queue`, `str8`, `mem_allocator`, `mem_utils`, `mem_os`, `file`, `cpath`, `log`, `shell_commander`, `shell_termcolour`, `shell_utils`, `prng/xorshift`, `uuid`, `tester`, `aliases`, `assert`, `misc_utils`, `platform` — plus their test files.

### Backward compatibility

Added `src/oldnames.h` with `#define OLD_NAME NEW_NAME` for every renamed symbol, organized by module under Constants → Types → Functions sections. Existing code that includes this file will compile without changes.

+      do not modify the License. You may add Your own attribution
+      notices within Derivative Works that You distribute, alongside
+      or as an addendum to the NOTICE text from the Work, provided
+      that such additional attribution notices cannot be construed
+      as modifying the License.
+
+  You may add Your own copyright statement to Your modifications and

+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+  any Contribution intentionally submitted for inclusion in the Work
+  by You to the Licensor shall be under the terms and conditions of

+  PARTICULAR PURPOSE. You are solely responsible for determining the

+  risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+  whether in tort (including negligence), contract, or otherwise,
+  unless required by applicable law (such as deliberate and grossly
+  negligent acts) or agreed to in writing, shall any Contributor be
+  liable to You for damages, including any direct, indirect, special,
+  incidental, or consequential damages of any character arising as a
+  result of this License or out of the use or inability to use the
+  Work (including but not limited to damages for loss of goodwill,
+  work stoppage, computer failure or malfunction, or any and all
+  other commercial damages or losses), even if such Contributor
+  has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+  the Work or Derivative Works thereof, You may choose to offer,
+  and charge a fee for, acceptance of support, warranty, indemnity,
+  or other liability obligations and/or rights consistent with this
+  License. However, in accepting such obligations, You may act only
