docs(notes): aggressive archive sweep of low-value decision records

Archive 21 implemented triplets whose shipped decisions are complete and
whose bodies no longer guide future work (one-off UI chrome, generator
applications whose scripts are self-explanatory, superseded implementation
detail, process history owned by current contracts/skills). Delete 4
rejected triplets whose premises are obsolete: the DeepReadonly proposal
(dev-invariants note now carries the alternative inline), the collapse
tool-owned presentation proposal (superseded by the shipped render-intent
union), retire-mid-turn-steering (steering is now load-bearing across
plan-mode/apiproxy/TUI), and single-session-ACP (automation-only ACP
resolved the question; multi-session isolation is pinned by tests).

Repair every inbound link: retarget intentional historical citations to
archived paths, replace decision-current citations with the surviving
authority, and fix the stale example-execute-over-tsx pointer in
pnpm-workspace.yaml. Re-record pairing sidecars and seal the archive
manifest (append-only; existing seals unchanged).

-An advisory loop-breaker, not a model-facing tool: it never appears in the tool list, never vetoes or rewrites a call, and adds exactly one behavior — it watches each agent's stream of tool calls, counts runs of consecutive calls to the same tool with identical canonicalized arguments, and at configured run lengths injects an escalating advisory reminder telling the model to stop repeating itself, re-read the last result, and either change approach or conclude. The decision (retry differently, gather more evidence, or finish) stays entirely with the model: a legitimately repeated call is delayed by nothing and blocked by nothing. Decision record: [the repeat-tool-guard Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-repeat-tool-guard.md).

-这是一个仅提供建议的循环中断器，而非面向模型的工具：它不会出现在工具列表中，不会否决或改写调用，只增加一种行为。它监视每个 agent（智能体）的工具调用流，统计以完全相同的规范化参数连续调用同一工具的次数；达到所配置的连续次数时，它会注入逐级增强的提示，要求模型停止重复、重新阅读上一次结果，并改用其他方案或结束任务。究竟是换一种方式重试、收集更多证据还是完成任务，仍完全由模型决定：合理的重复调用既不会延迟，也不会受阻。决策记录见 [repeat-tool-guard Agent Note](../../../.agents/notes/implemented/feature/2026-07-08-repeat-tool-guard.md)。
