fix(opencode): correct remaining agent/skill doc drift

- pr-review: replace invalid 'tea pr comment' with 'tea comment' (the
  former is not a tea subcommand)
- integrator: drop stray '-M' from client examples (-M is now
  --remote-option and requires an argument), use the canonical pytest
  integration command, and bump the CI image tag to v10
- test-writer: build fuzz targets via -DENABLE_FUZZ=ON instead of
  hand-rolled -fsanitize flags; fix the fuzz binary path
- cmake-expert: document -DSANITIZER=undefined, which is now live in
  CMakeLists.txt
- README: add --allow-unauthenticated to the plain-TCP server example,
  use --preserve for metadata (not -M), and use the canonical
  integration command
- AGENTS.md: use the canonical integration command
