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

* Update src/modules/ReplyBotModule.h

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

+
+            IMPORTANT: Distinguish between:
+            - Device/firmware bugs (crashes, reboots, lockups, radio/GPS/display/power issues) - these need device logs
+            - Build/release/packaging issues (missing files, CI failures, download problems) - these do NOT need device logs
+            - Documentation or website issues - these do NOT need device logs
+
+            If this is a device/firmware bug, request device logs and explain how to get them:
+
+            Web Flasher logs:
+            - Go to https://flasher.meshtastic.org
+            - Connect the device via USB and click Connect
+            - Open the device console/log output, reproduce the problem, then copy/download and attach/paste the logs
+
+            Meshtastic CLI logs:
+            - Run: meshtastic --port <serial-port> --noproto
+            - Reproduce the problem, then copy/paste the terminal output
+
+            Also request key context if missing: device model/variant, firmware version, region, steps to reproduce, expected vs actual.
+
+            Respond ONLY with valid JSON (no markdown, no code fences):
+            {"complete": true, "comment": "", "label": "none"}
+            OR
+            {"complete": false, "comment": "Your helpful comment", "label": "needs-logs"}
+
+            Use "needs-logs" ONLY if this is a device/firmware bug AND no logs are attached.
+            Use "needs-info" if basic info like firmware version or steps to reproduce are missing.
+            Use "none" if the issue is complete, is a feature request, or is a build/CI/packaging issue.

+ * specific text commands ("/ping", "/hello" and "/test") delivered either via a direct
+ * 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.
