src: update checkpoints to match v0.18.4.4

✓ Descriptive subject✓ Names a concrete action or component! No meaningful explanatory body

The short version

What changed, and why it matters

This commit is a routine maintenance update that adds a new blockchain checkpoint and updates version references in documentation. Checkpoints are a normal mechanism that help Monero nodes agree on the correct chain history and speed up initial synchronization. There is no indication of a security fix, vulnerability, or malicious change in the diff.

Recommended action

No security action required. Treat as a normal release synchronization commit.

Security signals we found

No strong security signals were identified.

Technical analysis

Evidence from the diff

The commit adds checkpoint 3541000 in src/checkpoints/checkpoints.cpp, updates the compiled-in checkpoint hash in src/cryptonote_core/blockchain.cpp, refreshes the binary checkpoints.dat file, and updates README.md to reference v0.18.4.4. These are standard release housekeeping changes for a hardcoded checkpoint list. No code logic, validation rules, or cryptographic handling is modified.
