test(miner): rename gittensory-miner/ams prose to loopover-miner/ams (batch 2)

[JSONbored]

Summary

• Part of the gittensory→loopover rebrand (Epic: complete the gittensory -> loopover rebrand (full cutover, no dual-support) #5705), phase 8b: rename remaining test-title prose. This batch covers 26 test/unit/*.ts files (governor, init, local-store, loop, mcp, and migrate clusters) whose describe()/it() titles, mkdtempSync tmpdir prefixes, and inline comments still used the bare gittensory-miner/gittensory-ams strings as human-readable labels.
• Also fixes a real stale string this sweep surfaced: packages/loopover-miner/lib/laptop-init.js's doctor-check detail message still said "run gittensory-miner init", telling self-hosters to run a CLI command that no longer exists (the real bin is loopover-miner). Test assertion updated in the same commit.
• No other functional/runtime identifier changes — purely test-label and comment prose.
