The opencode plugin template embedded the reminder string with backticks
around `graphify query "<question>"`. Because the plugin prepends
`echo "<reminder>" && <cmd>` to the user's bash command, those backticks
triggered bash command substitution: every grep/rg/find invocation silently
ran `graphify query "<question>"` and substituted its output
("No matching nodes found.") into the reminder text shown to the agent.
This both corrupted tool output with graphify noise, and actually spawned
a graphify process + loaded graph.json + ran a BFS traversal with the
literal token <question> on every search.
Fix: remove the backticks. Adds a guard comment in the template so future
editors don't reintroduce the bug, and a regression test that asserts the
reminder string contains no backticks and no $() constructs.
