Merge branch 'develop' into ximinez/vault-test

The existing code added the git commit info (`GIT_COMMIT_HASH` and `GIT_BRANCH`) to every file, which was a problem for leveraging `ccache` to cache build objects. This change adds a separate C++ file from where these compile-time variables are propagated to wherever they are needed. A new CMake file is added to set the commit info if the `git` binary is available.

+## Clang-tidy
+
+All code must pass `clang-tidy` checks according to the settings in [`.clang-tidy`](./.clang-tidy).
+
+There is a Continuous Integration job that runs clang-tidy on pull requests. The CI will check:
+
+- All changed C++ files (`.cpp`, `.h`, `.ipp`) when only code files are modified
+- **All files in the repository** when the `.clang-tidy` configuration file is changed
+
+This ensures that configuration changes don't introduce new warnings across the codebase.
+
+### Running clang-tidy locally
+
+Before running clang-tidy, you must build the project to generate required files (particularly protobuf headers). Refer to [`BUILD.md`](./BUILD.md) for build instructions.
+
+Then run clang-tidy on your local changes:
+
+```
+run-clang-tidy -p build src tests
+```
+
+This will check all source files in the `src` and `tests` directories using the compile commands from your `build` directory.

+# Using Nix Development Shell for xrpld Development
+
+This guide explains how to use Nix to set up a reproducible development environment for xrpld. Using Nix eliminates the need to manually install utilities and ensures consistent tooling across different machines.
+
+## Benefits of Using Nix
+
+- **Reproducible environment**: Everyone gets the same versions of tools and compilers
+- **No system pollution**: Dependencies are isolated and don't affect your system packages
+- **Multiple compiler versions**: Easily switch between different GCC and Clang versions
+- **Quick setup**: Get started with a single command
+- **Works on Linux and macOS**: Consistent experience across platforms
+
+## Install Nix
+
+Please follow [the official installation instructions of nix package manager](https://nixos.org/download/) for your system.
+
+## Entering the Development Shell
+
+### Basic Usage
+
+From the root of the xrpld repository, enter the default development shell:
+
+```bash
+nix --experimental-features 'nix-command flakes' develop
+```
+
+This will:
+
+- Download and set up all required development tools (CMake, Ninja, Conan, etc.)
+- Configure the appropriate compiler for your platform:
+  - **macOS**: Apple Clang (default system compiler)
+  - **Linux**: GCC 15
+
+The first time you run this command, it will take a few minutes to download and build the environment. Subsequent runs will be much faster.
+
+> [!TIP]
+> To avoid typing `--experimental-features 'nix-command flakes'` every time, you can permanently enable flakes by creating `~/.config/nix/nix.conf`:
+>
+> ```bash
+> mkdir -p ~/.config/nix
+> echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
+> ```
+>
+> After this, you can simply use `nix develop` instead.
+
+> [!NOTE]
+> The examples below assume you've enabled flakes in your config. If you haven't, add `--experimental-features 'nix-command flakes'` after each `nix` command.
+
+### Choosing a different compiler
+
+A compiler can be chosen by providing its name with the `.#` prefix, e.g. `nix develop .#gcc15`.
+Use `nix flake show` to see all the available development shells.
+
+Use `nix develop .#no_compiler` to use the compiler from your system.
+
+### Example Usage
+
+```bash
+# Use GCC 14
+nix develop .#gcc14
+
+# Use Clang 19
+nix develop .#clang19
+
+# Use default for your platform
+nix develop
+```
+
+### Using a different shell
+
+`nix develop` opens bash by default. If you want to use another shell this could be done by adding `-c` flag. For example:
+
+```bash
+nix develop -c zsh
+```
+
+## Building xrpld with Nix
+
+Once inside the Nix development shell, follow the standard [build instructions](../../BUILD.md#steps). The Nix shell provides all necessary tools (CMake, Ninja, Conan, etc.).
+
+## Automatic Activation with direnv
+
+[direnv](https://direnv.net/) or [nix-direnv](https://github.com/nix-community/nix-direnv) can automatically activate the Nix development shell when you enter the repository directory.
+
+## Conan and Prebuilt Packages
+

+ * a different allocator is in use, this function is a no-op and the report will

+ * @param journal Journal for diagnostic logging.
+ * @return Report containing before/after metrics and the trim result.

+ * @note If an alternative allocator (jemalloc/tcmalloc) is linked or preloaded,
+ *       calling glibc's malloc_trim may have no effect on the active heap. The
+ *       call is harmless but typically does not reclaim memory under those
+ *       allocators.
+ *
+ * @note Only memory served from glibc's sbrk/arena heaps is eligible for trim.
+ *       Large allocations satisfied via mmap are usually returned on free
+ *       independently of trimming.
+ *
+ * @note Intended for use after operations that free significant memory (e.g.,
+ *       cache sweeps, ledger cleanup, online delete). Consider rate limiting.
