standalone.mjs: memory_save ignores title/tags, uses content as title — breaks keyword search

[netyilei]

Summary

dist/standalone.mjs (MCP standalone mode) has 3 related bugs:

Bug 1: validate() doesn't extract title or tags

Lines 1515-1522, the memory_save case only extracts content, type, concepts, files:

case "memory_save": {
    const content = args["content"];
    if (typeof content !== "string" || !content.trim()) throw new Error("content is required");
    v.content = content;
    v.type = args["type"] || "fact";
    v.concepts = normalizeList(args["concepts"]);
    v.files = normalizeList(args["files"]);
    return v;
}

v.title and v.tags are never set.

Bug 2: handleLocal() stores content as title

Line 1613:

title: (v.content || "").slice(0, 80),

Should be v.title || (v.content || "").slice(0, 80).

Bug 3: search doesn't include tags
Lines 1637-1644, the search text concatenates title, content, files, concepts, sessionIds, id but not tags.

Impact
memory_save via standalone MCP always stores title == content (truncated to 80 chars)
tags parameter is silently discarded
Tags cannot be searched
Only affects standalone.mjs. The full REST API + iii-engine path is not affected.

Verified and fixed locally against v0.9.27.
