v0.8.0

Added

• Per-routine sync on the Routines page (#255, thanks @bcandido). Each routine now has its own Sync / Re-sync button, so you can create or re-create a single planned workout on Garmin without running a full sync. A single sync uses the same safe reconciliation as the bulk path: it only ever replaces a Garmin workout carrying hevy2garmin's provenance marker (never one you built by hand), persists the workout before scheduling so a mid-sync failure can't orphan or duplicate it, and restores the routine's existing scheduled dates.
• Redesigned Routines page (#255, thanks @bcandido). Routines are shown as cards with a clear on-Garmin / pending status, an expandable exercise list, and a per-routine schedule panel. A toolbar adds All / On Garmin / Pending filters (a "show only unsynced" view) and a name search, and a summary strip shows how many routines are on Garmin with a progress bar.
