+ * Resolve the stack for agent-context (re)scaffolding. Precedence:
+ *   1. explicit --server/--client overrides — the user is (re)declaring the stack;
+ *   2. the stack persisted in the prior manifest — ground truth from the last
+ *      init/refresh, reused so a correct multi-package stack line is never REGRESSED
+ *      by re-detecting from a root-only probe (issue #163: a monorepo's sibling-
+ *      package client and its Maven-built Kotlin are invisible at the root);
+ *   3. best-effort detection from the root probe — a fresh project with no prior.
+ * This governs EVERY path that runs writeAgentContext — refresh, `init --force`, and
+ * `--docs-only` — so a declared stack survives on all of them unless the user passes
+ * explicit overrides. resolveStack filters servers/clients to the valid vocabularies
+ * and self-detects when handed empty arrays, so passing the manifest's persisted
+ * string[]s (or nothing) straight through is safe — no need to special-case an empty
+ * or absent prior.
