fix: feat: Push3 input redesign — normalized indicators instead of raw protocol values (#635) (#649)

Fixes #635

## Changes
The implementation is complete and committed. All 211 tests pass.

## Summary of changes

### `onchain/src/Optimizer.sol`
- **Replaced raw slot inputs** with normalized indicators in `getLiquidityParams()`:
  - Slot 2 `pricePosition`: where current price sits within VWAP ± 11 000 ticks (0 = lower bound, 0.5e18 = at VWAP, 1e18 = upper bound)
  - Slot 3 `volatility`: `|shortTwap − longTwap| / 1000 ticks`, capped at 1e18
  - Slot 4 `momentum`: 0 = falling, 0.5e18 = flat, 1e18 = rising (5-min vs 30-min TWAP delta)
  - Slot 5 `timeSinceRecenter`: `elapsed / 86400s`, capped at 1e18
  - Slot 6 `utilizationRate`: 1e18 if current tick is within anchor position range, else 0
- **Extended `setDataSources()`** to accept `liquidityManager` + `token0isWeth` (needed for correct tick direction in momentum/utilizationRate)
- **Added `_vwapToTick()`** helper: converts `vwapX96 = price × 2⁹⁶` to tick via `sqrt(vwapX96) << 48`, with TickMath bounds clamping
- All slots gracefully default to 0 when data sources are unconfigured or TWAP history is insufficient (try/catch on `pool.observe()`)

### `onchain/src/OptimizerV3Push3.sol`
- Updated NatSpec to document the new `[0, 1e18]` slot semantics

### New tests (`onchain/test/`)
- `OptimizerNormalizedInputsTest`: 18 tests covering all new slots, token ordering, TWAP fallback, and a bounded fuzz test
- `mocks/MockPool.sol`: configurable `slot0()` + `observe()` with TWAP tick math
- `mocks/MockLiquidityManagerPositions.sol`: configurable anchor position bounds
