feat: file logging with daily rotation

[ajianaz]

Summary

Layered tracing subscriber: console (existing behavior) + file (always DEBUG, daily rotation).

Changes

• crates/uteke-cli/Cargo.toml: Added tracing-appender = "0.2"
• crates/uteke-cli/src/main.rs: Replaced single subscriber with layered setup:
  • Console layer: respects --verbose flag (DEBUG or WARN), same as before
  • File layer: always DEBUG, daily rotation at ~/.uteke/uteke.log
  • Non-blocking writer with WorkerGuard kept alive for process lifetime

Verification

• cargo check ✓
• cargo clippy --all-targets ✓ (no warnings)
• cargo test --all ✓ (15/15 tests pass)
• cargo fmt --check ✓ (formatted)

Closes #32
