v0.5.0

Added

• CLI mode — markfetch <url> fetches a URL and prints clean markdown to stdout. -o, --output <path> writes to a file (absolute or relative; relative paths resolve against cwd) with a confirmation on stdout. --help / --version work as expected. Bare markfetch (zero arguments) continues to start the MCP stdio server, so every existing MCP client config keeps working unchanged.
• commander runtime dependency (v14.x, 0 transitive deps) — used by the CLI adapter for argv parsing, help, and version.

Changed

• Source restructured into src/core.ts (pipeline + errors), src/mcp.ts (MCP adapter), src/cli.ts (CLI adapter), and src/index.ts (argv-discriminated dispatcher that lazy-imports the right adapter based on process.argv.length). No public-API change for MCP consumers — tool name, input schema, error codes, and output shape are byte-identical to 0.4.1. The lazy-import dispatcher makes the "stdout is reserved for MCP frames" invariant structural: cli.ts is never loaded in MCP mode, so no code that calls console.log is reachable from the MCP path.
• 3 inline return errorResult(...) sites in the MCP handler (extraction_failed, post-conversion too_large, save_failed) now throw MarkfetchError from core uniformly; both adapters catch and convert. Same observable error messages.

v0.4.1

Fixed

• bin entry in package.json uses dist/index.js instead of ./dist/index.js — npm 10+ stricter validation considered the leading ./ invalid and warned about silently stripping the entry on publish.

Changed

• README rewritten for npm publication: bold subtitle, badge row (npm/CI/node/license), comparison table vs. alternative approaches (built-in agent fetch, Playwright, mcp-server-fetch, CloudFlare /markdown), reference table for the 7 error codes, and a "What it is not" scope-boundary section.
• PRD: forward-looking statements consolidated under §7 "Deferred / Open Questions" so the body reflects current state only.
