fix: remove PayPal funding link, bump anyhow for RUSTSEC-2026-0190, resolve all clippy warnings

- Remove PayPal donate URL from .github/FUNDING.yml (keep saweria), fix trailing whitespace
- Update anyhow 1.0.102 -> 1.0.104 (RUSTSEC-2026-0190 unsoundness warning)
- Fix 25 clippy warnings across src/ (idiomatic fixes; two justified
  #[allow(too_many_arguments)] on internal pass-through helpers)
- Normalize formatting via cargo fmt
- Correct stale version reference in AGENTS.md (1.32.4 -> 1.34.0)
