repo-map.md was 173 KB (~43k tokens), too long to be part of every new
agent's context. The full gotcha text moves verbatim to context/gotchas.md
and the per-file inventory (with the old Wasm/CLI/Testing sections) to
context/file-inventory.md; the map keeps a one-or-two-line digest per
gotcha under the same numbers, so every `gotcha N` citation still resolves.
The doc-site manifest publishes the two new pages, and `gotchas` gets the
same gotcha-N anchors as `repo-map`.
