v1.3.3

Changed

• rmcp 1.3 → 1.6 (manifest + lockfile). Required code changes:
  • #[prompt_router] in rmcp-macros 1.4+ generates a private associated function by default — now passes vis = "pub(crate)" so XcStringsMcpServer::new() (in a different module) can call Self::prompt_router() once at startup.
  • The handler attributes now point at cached struct fields (#[tool_handler(router = self.tool_router)], #[prompt_handler(router = self.prompt_router)]) so the routers are built once in XcStringsMcpServer::new() instead of being rebuilt on every JSON-RPC dispatch (rmcp 1.4+ macros default to Self::tool_router() / Self::prompt_router() function calls, which would allocate a fresh HashMap + per-route Arc<closure> on each tools/call, tools/list, prompts/get, prompts/list).
• libc 0.2.183 → 0.2.186 (manifest + lockfile).
• Lockfile-only refreshes (manifest constraints unchanged): tokio 1.50 → 1.52.1 (spawn_blocking regression fix), indexmap 2.13 → 2.14 (hashbrown 0.16 → 0.17), clap 4.6.0 → 4.6.1, clap_complete 4.6.0 → 4.6.3, assert_cmd 2.2.0 → 2.2.1 (dev).
