v0.26.2

What's Changed

New Features

• feat(protocol): implement server/discover RPC (MCP SEP-2575) (#1354): Upgrades rmcp to v3.1.0 and replaces the previously commented-out placeholder with a real discover handler. Clients that support SEP-2575 can now call server/discover to retrieve supported protocol versions and capabilities without completing a full initialize handshake. Includes two new integration tests: stateless discovery before initialize, and discovery in an already-initialized session.

Bug Fixes

• fix(edit): remove CWD containment check from edit tools when no working_dir is set (#1353): Removes the implicit starts_with(cwd) guard from the edit_overwrite and edit_replace None-working_dir path. Absolute paths and ../ traversals that resolve outside the server's CWD are now accepted, consistent with the already-deployed Some-working_dir arm. Operators who require path confinement must pass working_dir explicitly. Four new integration tests cover the changed behaviour.

• fix(logging): remove McpLoggingLayer dead code (MCP SEP-2577) (#1351): Deletes the disabled log-consumer task together with McpLoggingLayer, LogEvent, and MessageVisitor, which were left unreachable after the SEP-2577 logging removal. Cleans up the corresponding module declarations, imports, and tests.

Maintenance

• chore(protocol): replace hardcoded 2025-11-25 with ProtocolVersion::LATEST (#1352): Eliminates eight hardcoded protocol version string literals across metrics, integration tests, and smoke tests. All sites now read ProtocolVersion::LATEST.as_str() so they auto-update when rmcp bumps LATEST.

• docs: audit and update all project markdown files for rmcp v2, SEP-2577, ProtocolVersion::LATEST, replace_all, and server/discover (#1355). No source code modified.
