fix: configure max message size for 4 MiB chunk transport

[mickvandijke]

Summary

• Bump saorsa-core to 0.12.0 which exposes max_message_size on CoreConfig
• Add configurable max_message_size to NodeConfig (default: 5 MiB via MAX_WIRE_MESSAGE_SIZE)
• Forward the setting to the QUIC transport layer so receive windows accommodate full-size (4 MiB) chunks plus serialization overhead
• Update e2e test to store and retrieve a max-size 4 MiB chunk, exercising QUIC stream flow-control limits end-to-end

Test plan

• cargo test passes (including the updated test_chunk_store_on_remote_node with 4 MiB payloads)
• cargo clippy --all-features -- -D clippy::panic -D clippy::unwrap_used -D clippy::expect_used clean
• Deploy to testnet and verify large chunk put/get works across nodes

Greptile Summary

Configures QUIC transport layer to handle maximum-size (4 MiB) chunk transfers by setting max_message_size to 5 MiB (accommodating serialization overhead). The change bumps saorsa-core to 0.12.0, adds the configurable max_message_size field to NodeConfig, forwards it to the transport layer, and updates the e2e test to exercise full-size chunk transfers across nodes.

Key changes:

• Dependency bump to saorsa-core 0.12.0 exposes max_message_size on CoreConfig
• New max_message_size configuration field (default: 5 MiB via MAX_WIRE_MESSAGE_SIZE)
• QUIC stream receive windows now accommodate 4 MiB chunks plus protocol overhead
• E2E test validates max-size chunk storage/retrieval across nodes under QUIC flow-control limits

Confidence Score: 5/5

• Safe to merge - clean implementation with comprehensive test coverage
• The PR makes focused, well-documented changes to support max-size chunk transfers. Code follows project standards (no unwrap/expect/panic in production code), includes clear documentation, and adds an e2e test that exercises the full 4 MiB payload path. The implementation correctly propagates the configuration from NodeConfig through to the QUIC transport layer.
• No files require special attention

Pull request overview

This PR configures the QUIC transport layer to properly handle maximum-size (4 MiB) data chunks by bumping the saorsa-core dependency and adding a configurable max_message_size setting. The change ensures that QUIC stream receive windows accommodate full-size chunks plus serialization overhead, preventing potential message truncation issues during transmission.

Changes:

• Bump saorsa-core from 0.11.1 to 0.12.0 which exposes max_message_size configuration option
• Add max_message_size field to NodeConfig with a default of 5 MiB (MAX_WIRE_MESSAGE_SIZE)
• Forward the setting from NodeConfig to saorsa-core's CoreNodeConfig in both production code and tests
• Update end-to-end test to use 4 MiB chunks instead of small chunks to exercise QUIC flow-control limits
