Three internal documentation references pointed at non-existent targets:
- docs/api.md: MessageItem.content linked to #addmessage, which has no
heading or anchor; corrected to #messageitem (the slug used by every
other MessageItem cross-reference and matching the ### MessageItem
heading).
- docs/cascade_runbook.md: the FD-exhaustion cross-ref used a single
hyphen where the GitHub slug of "FD exhaustion (`os error 24` /
EMFILE)" has a double hyphen (from the ` / ` separator); corrected to
#fd-exhaustion-os-error-24--emfile.
- use-cases/claude-code-plugin/skills/memory-tools.md: the always-injected
skill named two tools (search_memories, get_memory) that the MCP server
never exposes; replaced with the real evermem_search tool and its
params (query required, limit default 10 / max 20).
Markdown-only; no runtime behavior change.
