v0.7.0 — Gmail attachments straight into the repo, write audit log

[0.7.0] - 2026-09-11

Added

• Gmail attachment tools (optional, read-only OAuth via npm run auth -- --gmail): gmail_find_attachments lists messages and their attachments; github_commit_attachment takes one attachment, converts it on the server when it is an image (same options as github_commit_image) and commits it. A photo someone emailed reaches the repository without passing through any client machine.
• Write audit log: every write-tool call logs one JSON line to stderr (tool, outcome, duration, client user agent, identifiers such as post id, repo, branch, file paths; never content), visible with docker logs.

Changed

• docker-compose.yml mounts the whole secrets/ directory read-only at /secrets (service account, optional Gmail credentials) instead of the single file.
