0.15.1

Fixed

• Documentation lint uses patched TOML and math-rendering dependencies; runtime dependency pins are unchanged.

• Import recovery messages now include the required profile and use the max_text_chars setting name.
  The overview clarifies Sheets import versus editing and optional image search.

• Google listings and MCP argument construction append values without spreading unbounded arrays into calls.

• bin/release restarts itself once when the release brings a newer bin/release: folding the changelog
  fast-forwards main, and the shell went on reading the old script from the byte it had reached, so the rest of the
  run was a mix of old and new text. It now starts the new script over; a second change during that run stops it
  with run it again. Only the repository's own release is affected; the published package does not change.

• A broken config file now says which key is wrong. Instead of only "drive configuration is invalid",
  drive names the first bad key and why: profiles.work.principal is missing, colour is not a known setting,
  profiles.work.read_only has the wrong type or is out of range. An old camelCase key set beside its new
  snake_case name says which one to keep. The message never shows a value from the file.
