- rust.yml: move clippy to nightly-2026-04-14 (was stable); also pin
fmt to the same nightly date for consistency. Both jobs now use the
dated nightly and the run-step uses `cargo +nightly-2026-04-14 ...`.
- AGENTS.md: update developer commands to match CI.
- Duration constructors: replace `Duration::from_secs(N * 60)` /
`Duration::from_millis(N * 1000)` with `from_mins` / `from_secs` /
`from_hours` across the workspace to satisfy clippy's new
`duration_suboptimal_units` lint. std::time::Duration only — custom
`settings::duration::Duration` sites kept on `from_secs`.
- map/unwrap_or cleanup: `.map(f).unwrap_or(v)` → `.map_or(v, f)`,
`.map(f).unwrap_or(false)` on Result → `.is_ok_and(f)`, per
`clippy::map_unwrap_or`.
- Misc lints: collapse nested `if` into match guard in
handler/llm/api.rs and run_state.rs; replace `columns.len() > 0`
with `!columns.is_empty()`; switch a pair of `sort_by` calls to
`sort_by_key`.
