chore(release): v0.8.0

[brickfrog]

Release v0.8.0 — ergonomics, plus the core extreme-year arithmetic hardening.

Added

• Duration::as_seconds_f64 / as_minutes_f64 / as_hours_f64. (Add fractional Duration total accessors #43)
• Duration::humanize. (feat: add Duration humanize #46)
• Date::parse_ordinal / parse_iso_week. (Add ISO ordinal and week-date parsing #45)
• DateTime::format_fixed (sortable fixed-width). (Add DateTime format_fixed #44)
• DateTime::format_with (brace-token DSL). (Add DateTime::format_with token DSL #47)
• Date::add_days_checked / add_months_checked / add_years_checked. (fix: harden Date extreme-year arithmetic #42)

Changed

• Hardened Date arithmetic against extreme-year Int overflow: formatting no longer aborts at any Int year; Int64 epoch-day math is correct across the full Int year range; from_iso_week raises on residual overflow. (fix: harden Date extreme-year arithmetic #42)

Fixed

• Date::format / to_json for BCE years now emit ISO 8601 expanded form (-0001-01-01) instead of the malformed 000-1-01-01. (fix: harden Date extreme-year arithmetic #42)

CHANGELOG + version bump (0.7.0 → 0.8.0) + README docs only.
