* fix(agent-instructions): budget the user-global and project chains separately
The user-global and project instruction files shared one maxBytes and the user-global files were the broadest, so a large project chain omitted them first. Each chain now renders under maxBytes on its own and the results share one system-reminder frame: unchanged output when everything fits or one chain is empty, at most twice maxBytes otherwise. The project chain keeps its omit-broadest-first, truncate-last rule; reconciliation batches follow the same split; the maxBytes key and the baseline identity are unchanged.
Tests cover the fast paths, both chains fitting only separately, each chain over its own budget, the 2 × maxBytes boundary at exact and tiny limits, multibyte content, reconciliation batches, and a resumed single-budget baseline receiving the user-global file as one transition. The agent-instructions-budget snapshot is refreshed and agent-instructions-budget-chains is added. README, Config.maxBytes JSDoc, the configuration catalog, a new Agent Note, and an upgrade guide state the per-chain bound.
* fix(agent-instructions): keep loaded order in merged frames and note the unshared chain budget
A merged frame now lists sections, omissions and truncations in the loaded order, so a reconciliation batch renders its items in one order whether or not it fits a single budget. The guard comment states only the invariant and points to the Agent Note; the intro selection states its rule. The README names the unshared budget between chains.
