Subject: [PATCH 01/14] feat(mcp): add gittensory_find_opportunities tool to
 the hosted /mcp Worker

Register gittensory_find_opportunities in the hosted MCP server composing
the ranker from gittensory-engine into a single advisory, metadata-only,
no-writes tool call. Accepts a repo target list or search query plus an
optional MinerGoalSpec (lane, minRankScore, languages) and a result cap.

For each target repo, reads cached open issues and open PRs, computes
dupRisk from linked-issue claim overlap, freshness from issue age, and
a composite rankScore via rankOpportunityScore. Returns a public-safe
ranked array (owner, repo, issueNumber, title, rankScore, laneFit,
freshness, dupRisk, aiPolicyAllowed) sorted by rankScore descending.

Closes #2308
