monad: v0.14.3
AI Summary
Monad releases v0.14.3 with robustness fixes addressing DbCache assertion failures, increased MIN_HISTORY_LENGTH floor from 257 to 300 blocks to prevent forced state syncs under disk pressure, and corrected EVM assembler PUSH0 encoding. The update also includes performance optimizations to trie spans and database operations.

## Robustness fixes
- **[Execution]** Fix `DbCache` assert-fail when reading finalized state older than latest finalized block
- Ref: [PR #2190](https://github.com/category-labs/monad/pull/2190)
- Replaces assertion with explicit checks; fixes incorrect `truncated` value propagation when walking the chain back past the latest finalized block
- **[Execution]** Raise `MIN_HISTORY_LENGTH` floor from 257 to 300
- Ref: [PR #2217](https://github.com/category-labs/monad/pull/2217)
- Execution requires 256 history blocks for the block hash buffer; the old floor of 257 left only a one-block margin. Under disk pressure, history could shrink below 256 after a restart, forcing a full statesync. New floor gives ~44 blocks of headroom; also bumps the stored cap on existing DBs at init time so nodes carried over from an older binary aren't pinned at 257.
- **[Execution]** Fix `evm-as` PushLabel encoding at offset zero for pre-Shanghai targets
- Ref: [PR #2213](https://github.com/category-labs/monad/pull/2213)
- Fixes incorrect `PUSH0` encoding in the EVM assembler for pre-Shanghai code paths
## Performance changes
- **[Execution]** Extend trie span optimization to fnext, child_off, and SharedPtr arrays
- Ref: [PR #2176](https://github.com/category-labs/monad/pull/2176)
- **[Execution]** Remove inflight read coalescing from rwdb find path
- Ref: [PR #2183](https://github.com/category-labs/monad/pull/2183)
- **[Execution]** Elide DB fetch in `State::is_touched`
- Ref: [PR #2198](https://github.com/category-labs/monad/pull/2198)
