/**
 * invocation-status.ts — the status text ChatGPT shows while a tool runs and
 * after it completes.
 *
 * Wire form (OpenAI Apps SDK reference, "Tool descriptor parameters"):
 *   _meta["openai/toolInvocation/invoking"]  ≤ 64 chars, shown during the call
 *   _meta["openai/toolInvocation/invoked"]   ≤ 64 chars, shown when it returns
 * Both are ChatGPT-only; other hosts ignore the keys. Emitted by buildUiMeta
 * (src/tools/ui-meta.ts), the one path both transports' tools/list share.
 *
 * Copy rules: name the thing being made in the user's words, so the wait reads
 * as progress rather than plumbing. `explore_*` tools say "ready" (a thing to
 * look at); `ephemeris_*` tools say "computed" / "found" (numbers) — the same
 * picture-vs-data split the descriptions make. Never promise a render:
 * `explore_*` fall back to text in hosts without MCP Apps.
 *
 * Every core tool must have an entry (test/invocation-status.test.ts); tools
 * outside core may have one. Keep both strings under MAX_STATUS_CHARS.
