feat(cli): add a changelog command for recent product updates

[Zach Dunn (zachdunn)]

Summary

Adds releases changelog, the counterpart of uploads changelog: print recent product updates in the terminal, then a link to the full changelog.

The feed is the self-published releases-sh org already in the registry (the same source releases.sh/updates renders). --json and the local stdio MCP changelog tool share that document.

This is a keyless reader command, distinct from releases admin source changelog (the key-gated per-source CHANGELOG.md wrapper).

releases changelog
releases changelog --limit 10
releases changelog --json

Test plan

• bun test tests/unit/product-changelog.test.ts tests/cli/product-changelog.test.ts tests/unit/mcp-changelog.test.ts
• bun run check
• Live releases changelog / --json against api.releases.sh
• releases changelog --help includes Examples
• releases admin source changelog --help is unchanged

📝 Walkthrough

Walkthrough

The change adds a product changelog module that reads releases.sh updates, formats changelog entries, and exposes them through the releases changelog CLI command and the local MCP changelog tool. Documentation, help output, tests, and release metadata are updated.

Changes

Product changelog

Layer / File(s)	Summary
Changelog data and formatting src/lib/product-changelog.ts, tests/unit/product-changelog.test.ts	The new module maps LatestRelease rows into changelog entries, validates limits, formats terminal output, and fetches the releases-sh feed. Unit tests cover mapping, formatting, limits, and fetching.
CLI command integration src/cli/commands/product-changelog.ts, src/cli/program.ts, tests/cli/*	The CLI registers releases changelog with --limit and --json options. It validates limits and supports human-readable and JSON output. CLI tests cover help and invalid limits.
MCP tool integration src/mcp/server.ts, tests/unit/mcp-changelog.test.ts	The local MCP server exposes a changelog tool with bounded limits. Tests verify registration, JSON output, and the releases-sh API request.
Documentation and release metadata .changeset/cli-changelog.md, AGENTS.md, README.md, skills/releases-cli/SKILL.md, skills/releases-cli/references/reader.md	The command, MCP tool, output fields, limits, and minor release are documented.

Merge Risk: 🔵 Low · up to 96ac3

The changelog MCP tool is implemented, but AGENTS.md does not yet document its limit, JSON fields, or read-only behavior. This is a low-impact documentation gap suitable for follow-up.
