build: v3.1.0

[Schlagonia]

Overview

This bumps the Tokenized Strategy API to v3.1.0 and adds constant accrual accounting while keeping the existing report flow available for harvest-style accounting.

Constant Accrual

• ERC4626 views and write paths now use the strategy current _totalAssets() estimate once the accounting latch opens.
• Deposits, mints, withdrawals, redeems, and relevant management setters sync through _accrue() before changing state.
• Gains become visible in PPS as they accrue. Losses burn locked-profit buffer shares where possible, then flow through to PPS.
• Performance and protocol fees are minted on accrued profit using the post-accrual PPS.
• report() keeps the same role: it still calls _harvestAndReport(), records harvestable or lumpy deltas, charges fees, and locks reported profit according to profitMaxUnlockTime.

Other Changes

• Splits read-only valuation into _totalAssets() and mutable reporting into _harvestAndReport().
• Adds strategyTotalAssets() as a public view so integrations and the tokenized strategy can read the strategy valuation directly.
• Adds TokenizedStrategyLib so strategy code can read tokenized strategy storage and views without the old self-call pattern.
• Makes BaseStrategy initialization overridable for custom management, keeper, and performance fee recipient setup.
• Adds lastAccrual() and lastTotalAssets() views for accounting state.
• Mints dead shares for unsolicited assets before first deposit to avoid first depositor capture.
• Blocks transfers from the strategy itself so locked-profit buffer shares cannot be moved.
• Expands tests for live accrual, fee syncs, loss handling, public total-assets reads, library views, custom init, and profit locking.
