DM pairing + Telegram channel improvements (#17)

* feat: Implement DM pairing for channels - Introduced a new pairing system to manage direct messages from unknown senders. - Added `PairingStore` to handle pending requests and allowlist management. - Implemented CLI commands for listing and approving pairing requests. - Updated Telegram channel to utilize the new pairing logic, including workspace paths for storing pairing data. - Enhanced WASM channel integration to support pairing functionality. This feature enhances security by requiring approval for unknown senders before they can interact with the agent. * Enhance Telegram channel support with media captioning and DM pairing features - Added support for media captions in Telegram messages, allowing for richer content handling. - Updated message processing to utilize either text or caption, improving message flexibility. - Enhanced DM pairing functionality to include approval and listing capabilities for direct messages. - Updated feature parity documentation to reflect new capabilities and improvements in Telegram integration. * Update README and BUILDING_CHANNELS documentation for Telegram channel integration - Enhanced README with instructions for building and running the Telegram channel, including a note on running `./scripts/build-all.sh` for full releases. - Added detailed steps in BUILDING_CHANNELS.md for building and deploying the Telegram channel, emphasizing the need to run `./channels-src/telegram/build.sh` before building the main crate to ensure updated WASM is included. - Updated CLI module to expose a new command for pairing with store functionality. * Implement build script for Telegram channel WASM and enhance pairing error handling - Added a new `build.rs` script to automate the compilation of the Telegram channel's WASM binary from source, ensuring reproducible builds and emphasizing supply chain security by preventing committed binaries. - Updated `BUILDING_CHANNELS.md` to reflect the new build process and the importance of not committing compiled binaries. - Enhanced error handling in the pairing approval process to include rate limiting for failed attempts, improving security and user feedback. * Remove Telegram channel WASM binary file as part of the build process cleanup, ensuring no committed binaries are present in the repository.

+//! Build script: compile Telegram channel WASM from source.
+//!
+//! Do not commit compiled WASM binaries — they are a supply chain risk.
+//! This script builds telegram.wasm from channels-src/telegram before the main crate compiles.
+//!
+//! Reproducible build:
+//!   cargo build --release
+//! (build.rs invokes the channel build automatically)
+//!
+//! Prerequisites: rustup target add wasm32-wasip2, cargo install wasm-tools
