Merge branch 'master' into 'rnou/fix_verbs'

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres

to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## Unreleased

## [Unreleased]

### New

  - directory optimization with compression and reattemp ([!270](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/270))

    - Refactor sfind so it can use SLURM_ environment variables to ask to different servers.

    - Create a sample bash script to gather all the info (map->reduce)

    - Compress directory data with zstd.

    - Make a new config.hpp option for controlling the compression

    - If directory buffer is not enough it will reattempt with the exact size

### Changed 

### Fixed

## [0.9.5] - 2025-08

### New

  - Added cppcheck code checking capabilities ([!214](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/214))

  - Tests to cover proxy and (malleability) ([!222](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/222))

    - execve set reentrant_guard as true, so once it returns (vfork) the parent had syscall disabled.

    - debug should be still set to debug level on syscall for vfork.

    - In MN5 gkfs_libc.hpp needs to have the libc signatures.

  - Thread local storage produces some seg fault in Mogon-2 with syscall ([!266](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/266))

    - using pthread functions

- `LIBGKFS_METRICS_IP_PORT` - Enable flushing to a set ZeroMQ server (replaces `LIBGKFS_METRICS_PATH`).

- `LIBGKFS_PROXY_PID_FILE` - Path to the proxy pid file (when using the GekkoFS proxy).

- `LIBGKFS_NUM_REPL` - Number of replicas for data.

#### Directory optimizations

Set `true` the variable `use_dirents_compression` available at `include/config.hpp` to transfer directories compressed with zstd.

#### Caching

##### Dentry cache

Improves performance for `ls -l` type operations by caching file metadata for subsequent `stat()` operations during

    the :ref:`step-by-step installation<step_by_step_installation>` section

    before attempting a manual install.
