v0.7.0 - Trusted Publishing + CI

What's New

• Trusted Publisher workflow - npm releases are now published automatically via GitHub Releases using OIDC (no long-lived tokens)
• CI badge in README
• Node.js 20+ requirement - bumped from 18 to match CI matrix and vitest compatibility
• Doc fixes - corrected stale tool counts in CLAUDE.md, version refs in README, dot notation in CONTRIBUTING.md

Changes since v0.6.0

• ci: add npm trusted publisher workflow (publish.yml)
• ci: add GitHub Actions CI for build + test on Node 20/22
• docs: bump Node.js requirement to 20
• docs: add CI status badge
• fix: update stale tool counts, version refs, and dot notation in docs
• fix: update package description to 25 tools

v0.6.0 - Bug Fixes + 5 New Tools

Bug Fixes

• Fixed POST body encoding on publisher tools - setAchievement, uploadLeaderboardScore, and grantInventoryItem now send params as application/x-www-form-urlencoded body instead of query string params, matching what the Steam Partner API expects. Added steamPartnerPost() helper.
• Removed dead variable in grantInventoryItem.ts (itemJson was built but never used).
• Renamed term to query in steam_searchApps input schema for discoverability.
• Improved leaderboard ID docs - steam_getLeaderboardEntries now clearly states the numeric ID requirement and where to find it in Steamworks.
• Better 400/403 errors on write tools - publisher tools now return actionable guidance about API key type and IP allowlisting instead of raw HTTP status.
• Renamed all tool names from dot notation (steam.toolName) to underscore notation (steam_toolName) to fix Cursor MCP bridge routing conflicts.

v0.2.1 - Polish

Quality improvements and test coverage.

New:

• Retry with exponential backoff on HTTP 429 (up to 2 retries, reads Retry-After header)
• README badges (npm version, license, Node.js version)

Fixed:

• Input validation: steamid fields now enforce 17-digit format, publishedfileid requires digits-only
• getLeaderboardEntries validates that steamid is provided for AroundUser/Friends requests
• CLAUDE.md rule count (3 -> 4)

Housekeeping:

• Added homepage/bugs fields to package.json
• Extended .gitignore (OS files, IDE dirs, coverage)
