2111b92: Add the query-code MCP tool and the ctx7 code command. They search and read a library's source code at the version its docs describe: grep with ripgrep's options, plus definition, references, outline, read and list. ctx7 library marks the libraries whose source is searchable, and resolve-library-id does so with the research preview on. The MCP tool is part of the research preview: it is listed only with --research-preview, CONTEXT7_RESEARCH_PREVIEW=1 or ?research_preview=1.
7765f35: Add the get-upgrade-guide research preview tool: everything that changes between two versions of a library in one response, from the release notes and guides of every release in between and the public API diff of both versions.
