fix: Simplify Reddit prompt and increase search volume

OpenAI's web_search doesn't reliably find recent Reddit content.
Strategy change: request MORE threads and let server-side date
filtering handle it.

Changes:
- Increased depth config (20-30 → 30-50 default)
- Simplified prompt to search broadly and include all matches
- Let server-side date filter remove old content
- Removed aggressive pre-filtering that was limiting results

Tradeoff: Some topics have more X coverage than Reddit due to
web_search limitations. This is acceptable.

 STEP 1: EXTRACT THE CORE SUBJECT
-Strip qualifiers and get the MAIN NOUN/PRODUCT/TOPIC:
+Get the MAIN NOUN/PRODUCT/TOPIC:
 - "best nano banana prompting practices" → "nano banana"
 - "killer features of clawdbot" → "clawdbot"
-- "top Claude Code skills" → "Claude Code skills"
+- "top Claude Code skills" → "Claude Code"
-DO NOT search for "best", "top", "tips", "practices" - just the core subject.
+DO NOT include "best", "top", "tips", "practices", "features" in your search.
 
-STEP 2: SEARCH FOR RECENT CONTENT (CRITICAL)
+STEP 2: SEARCH BROADLY
-You MUST search with date filters to find recent threads:
+Search for the core subject:
-1. "[core subject] site:reddit.com after:{from_date}"
+1. "[core subject] site:reddit.com"
-2. "reddit [core subject] 2026" or "reddit [core subject] January 2026"
+2. "reddit [core subject]"
-3. "[core subject] site:reddit.com/r/"
+3. "[core subject] reddit"
 
-The goal is threads from {from_date} to {to_date}. Older threads are NOT useful.
+Return as many relevant threads as you find. We filter by date server-side.
 
-STEP 3: VALIDATE DATES
+STEP 3: INCLUDE ALL MATCHES
-Before including a thread, verify its date is AFTER {from_date}.
+- Include ALL threads about the core subject
-If you cannot determine the date, set date to null.
+- Set date to "YYYY-MM-DD" if you can determine it, otherwise null
-EXCLUDE threads you know are older than {from_date}.
+- We verify dates and filter old content server-side
+- DO NOT pre-filter aggressively - include anything relevant
