v3.9.1

[3.9.1] - 2026-08-02

Theme: Documentation and project-infrastructure release. No runtime code changed — the package is functionally identical to 3.9.0.

Added

• Sponsorship program (#442) — SPONSORSHIP.md (five tiers plus the rules), SPONSORS.md, and a sponsors.json single source of truth rendered into all 12 READMEs by scripts/render_sponsors.py. Adding a sponsor is one JSON edit instead of thirteen hand edits, and CI (--check) fails on drift. .github/FUNDING.yml gains GitHub Sponsors alongside Buy Me a Coffee.
• Sponsor URLs are policy-checked in code — the renderer refuses any sponsor link carrying utm_/ref/fbclid/gclid-style parameters, enforcing rule 4 of the published policy. This immediately caught 24 UTM-tagged links already present across the READMEs; all sponsor links are now clean.

Changed

• README restructured into a lean landing page — 1,371 → 424 lines, with the deep-dive material moved behind links to the docs/ pages that already covered it. Mirrored across all 11 translations (~16,500 → ~5,100 lines total), each keeping its machine-translation notice and language switcher.
• Repo root decluttered — BULLETPROOF_QUICKSTART.md → docs/getting-started/, the dated DOCUMENTATION_AUDIT_REPORT_2026-05-30.md → docs/archive/historical/, with every reference repointed.
• QWEN.md reduced from 719 to 64 lines — it duplicated AGENTS.md while advertising three different version numbers at once (v3.6.0, 3.3.0, and "17+ source types" beside "18 source types"). It is now a pointer to AGENTS.md that keeps the essential commands and conventions inline and carries no hardcoded version.

Fixed

• Stale and incorrect README claims corrected against the codebase — version badge 3.7.0 → 3.9.0; the documented scan --quick|--comprehensive|--enhance flags do not exist and are now create --preset quick|standard|comprehensive; export targets "16 formats"/"21 platforms" → 22; CLI reference "all 20 commands" → 19; the install-agent table 15 → 19 entries; workflow presets "24+" → 68; and the dead # skill-seekers list-configs line removed.
• Three overlapping troubleshooting guides unified — root TROUBLESHOOTING.md (485 lines), docs/TROUBLESHOOTING.md (1,102) and docs/user-guide/06-troubleshooting.md (108) shared only 2 of 22 headings, so none was a stale copy. docs/TROUBLESHOOTING.md is now the single comprehensive reference (1,398 lines) with the five sections that existed only at root merged in; the user-guide chapter stays as the short entry in the numbered series.
• 92 broken relative links repaired across the docs tree (109 → 17) — targets relinked to their real locations, case/separator mismatches fixed (integrations/cursor.md → CURSOR.md, advanced/api-reference.md → reference/API_REFERENCE.md), and links to never-written docs unlinked rather than left as 404s. The remaining 17 are intentional (template placeholders, illustrative generated-output samples, archived snapshots).
• Version stamps refreshed in 28 docs files (14 English + 14 zh-CN) from v3.6.0 to v3.9.0. Historical references in MIGRATION_GUIDE.md and "added in vX.Y.Z" notes are deliberately untouched.
• test_cli_paths.py no longer pins a version literal — it asserted "3.9.0" and broke the moment the dev version moved, the same fragility already fixed in test_package_structure.py. It now tracks skill_seekers.__version__.
• The published MCP Docker image was broken and is now fixed — Dockerfile.mcp installed the MCP SDK with a bare pip install mcp, bypassing the mcp>=1.25,<2 pin in pyproject.toml. Once mcp 2.0.0 shipped, that resolved to 2.x, where FastMCP moved out of mcp.server, so the container died on startup with cannot import name 'FastMCP'. It now installs via the [mcp] extra so the pin applies. Verified by building the image and confirming the server answers /health in ~4s on mcp 1.29.0.
• Docker MCP image smoke test polls for readiness — the PR-only Test MCP image job waited a fixed 10s before curling /health, then failed with no diagnostics. It now polls for up to 60s and dumps container logs on timeout. That log dump is what surfaced the broken-image bug above, which the old silent failure had masked for months.
