engine: v2.0.0

2.0.0 (2026-07-14)

⚠ BREAKING CHANGES

• miner: the miner's default config directory and every gittensory_miner_* Prometheus metric name changed; no dual-read/alias, per the epic's full-cutover mandate (#5705). A self-hoster's existing ~/.config/gittensory-miner state does not migrate automatically.
• github: the bot no longer recognizes @gittensory as a command trigger anywhere -- only @Loopover works. Any saved PR-comment template, bookmark, or muscle-memory referencing @gittensory must be updated to @Loopover .
• miner: every GITTENSORY_MINER_/GITTENSORY_API_TOKEN_FILE/ GITTENSORY_MCP_TOKEN_FILE/GITTENSORY_MEM_LIMIT/GITTENSORY_REPORTING_ env var an existing self-hosted AMS/miner deployment sets must be renamed to its LOOPOVER_ equivalent -- the old names are no longer read.
• remove gittensory-engine's settings.gateCheckMode yml back-compat parsing (#5373) (#5463)
