Find where a topic came up across meetings

**Objective:** Find every place `{search-text}` was discussed in meeting transcripts, optionally only for speaker `{speaker}` and only after `{from-date}`.

**Step 1: Search**

Call `granola-get-transcript` with `text.contains` set to `{search-text}`, plus `speaker` set to `{speaker}` if given and `note-created.from` set to `{from-date}` if given. Set `max-records` to 100. If nothing returns, try one or two close variants of the wording, then report that nothing was found.

**Step 2: Group by meeting**

Group the lines by `note-id`. For the five meetings with the most hits, call `granola-get-note` with `id` set to the note id to get the title, date and owner.

**Step 3: Report**

* Total lines and meetings found
* For each meeting: title, date, who spoke, and a short quote with timing
* A short synthesis of how the position or sentiment changed over time

**Rules & Guidelines:**

* Read-only. Only call `granola-get-transcript` and `granola-get-note`.
* Quote exactly; do not paraphrase inside quote marks.
* If the 100-record cap was reached, say results may be incomplete and suggest narrowing by date or speaker.

**Validation:**

* If `{search-text}` is very short or common, ask for something more specific first.
