Scribe v1.3.0

Tagged retroactively on 1 October 2026. This commit merged to main on 14 September 2026 and has been what marketplace installers receive since then, but it was never tagged.

Upstream pin 1.25.2 to 1.26.1

• Pins workspace-mcp@1.26.1 (released 2026-09-13).
• Tool surface verified by live MCP handshake of both versions: 122 to 123 tools. One was added (manage_sheet_tab), none were removed, and all 11 parameter changes are additive. MINOR, not MAJOR.

Fixes that reach Scribe users

• inspect_doc_structure returned HTTP 400 on every call made with includeTabsContent. It now works.
• run_script_function passed a project ID where the API wants a deployment ID. Fixed.
• Corrupt .docx, .xlsx and .pptx files now report as damaged.
• Comment tools return real multi-line output.
• Startup errors log at ERROR level.

Unchanged

GFM tables still flatten on populate_from_markdown, because upstream PR #929 is still open. The verification and repair guidance in the docs skill stays load-bearing.

Note - marketplace.json still said 1.2.0 in this release. v1.3.1 aligns both manifests.
