v0.2.6

Implements Synod 0.2. Tools for people and agents: synod doc and synod explain answer questions from the command line, synod new and synod get start a module and fetch what it requires, and synod mcp serves the lot to agents that have no shell.

Added

• synod doc [package]: prints a package's phrases, records and Node fields from its source, or lists the visible packages. --json prints synod-doc/1, --scope file gives the scope of one file for editors, --overlay file reads unsaved buffers and --catalog prints the std catalog as Markdown.
• synod explain [code]: explains a diagnostic code with an example and its fix, or lists the 38 codes. --json prints synod-explain/1; --catalog prints the table of codes, meanings and fixes as Markdown.
• synod new <dir> [--module path] [--lib]: creates a module with synod.mod, .gitignore, a package folder and a demo.synod main file that checks and runs.
• synod get [module@version]: makes vendor/ and synod.sum match the build list, downloading what the store lacks with git and verifying the commit and the tree hash.
• synod mcp [--root dir]: a stdio MCP server with the tools doc, explain, check, run_summary and fmt; each gives the text of the matching command.

Changed

• The embedded std matches std v0.2.2: every phrase, record and field has a doc comment, and these comments are what synod doc prints.
• synod version lists the new formats: formats synod-trace/1 synod-scene/1 synod-check/1 synod-doc/1 synod-explain/1. The same list is in synod.version() of the WebAssembly build.
