fix: feat: LLM seed — Fee Maximizer optimizer (#673) (#696)

Fixes #673

## Changes
Done. Here's a summary of what was implemented:

## Changes

**`tools/push3-evolution/seeds/llm_fee_maximizer.push3`** (new file)
A Push3 optimizer seed implementing the "every trade pays us" philosophy. It reads `percentageStaked` (slot 0) and `averageTaxRate` (slot 1), then branches on two thresholds:
- Staking threshold: 60% (bullish vs. neutral sentiment)
- Tax threshold: 10% of 1e18 (high vs. low swap volume)

Strategy matrix:
| | tax < 10% | tax ≥ 10% |
|---|---|---|
| **staked < 60%** | AS=0.70, AW=60, DD=0.50 | AS=0.80, AW=80, DD=0.60 |
| **staked ≥ 60%** | AS=0.90, AW=40, DD=0.80 | AS=0.95, AW=50, DD=0.90 |

CI is always 0. Anchor share is always ≥ 0.70e18 (capital stays in fee-earning zone). High staking shifts discovery depth up; high tax widens the anchor to capture more swap volume.

**`tools/push3-evolution/seeds/manifest.jsonl`** — new entry for `llm_fee_maximizer.push3` with `origin=llm`.

Transpiled successfully: 48-line Solidity function body, outputs correctly bound to `ci`, `anchorShare`, `anchorWidth`, `discoveryDepth`.

+;; Fee Maximizer optimizer — LLM seed
+;;
+;; Philosophy: "every trade pays us."
+;; Concentrate liquidity in high-traffic price ranges by keeping anchor share
+;; high and anchor width wide enough to capture price movement volatility.
+;;
+;; Inputs on DYADIC stack (slot 0 on top, slot 7 at bottom):
+;;   [0] percentageStaked      (0 to 1e18, where 1e18 = 100%)
+;;   [1] averageTaxRate        (0 to 1e18)
+;;   [2..7] reserved / future indicators
+;;
+;; Outputs (bottom-to-top push order → top = ci):
+;;   discoveryDepth  (bottom)  — DD: aggressive upside discovery
+;;   anchorWidth               — AW: wide coverage of price movement
+;;   anchorShare               — AS: most ETH in the fee-earning zone
+;;   ci              (top)     — always 0 (no capital inefficiency)
+;;
+;; Strategy matrix (staking threshold: 60%, tax threshold: 10%):
+;;
+;;                  | tax < 10%                 | tax >= 10%
+;;   ---------------+---------------------------+--------------------------
+;;   staked < 60%   | CI=0 AS=0.70 AW=60 DD=0.50 | CI=0 AS=0.80 AW=80 DD=0.60
+;;   staked >= 60%  | CI=0 AS=0.90 AW=40 DD=0.80 | CI=0 AS=0.95 AW=50 DD=0.90
+;;
+;; Rationale:
+;;   - High staking → bullish sentiment → push discovery depth up
+;;   - High tax → more staking/trade activity → widen anchor to capture volume
+;;   - Anchor share always > 0.70 so capital stays in the fee-earning zone
