Merge branch 'develop' into baseui_statusmessage

* Implement Meshtastic reply bot module with ping and status features

Adds a reply bot module that listens for /ping, /hello, and /test commands received via direct messages or broadcasts on the primary channel. The module always replies via direct message to the sender only, reporting hop count, RSSI, and SNR. Per-sender cooldowns are enforced to reduce network spam, and the module can be excluded at build time via a compile flag. Updates include the new module source files and required build configuration changes.

* Update ReplyBotModule.cpp

Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>

* Update src/modules/ReplyBotModule.h

Match the existing MESHTASTIC_EXCLUDE_* guard pattern so the module is excluded by default.

+ * message (DM) or a broadcast on the primary channel.  When a supported command is
+ * received the bot responds with a short status message that includes the hop count
+ * (minimum number of relays), RSSI and SNR of the received packet.  To avoid spamming
+ * the network it enforces a per‑sender cooldown between responses.  By default the
+ * module is enabled; define MESHTASTIC_EXCLUDE_REPLYBOT at build time to exclude it
+ * entirely.  See the official firmware documentation for guidance on adding modules.
