feat: Health Connect segment fidelity (rest segments, real names, weight-fallback)

[Devasy]

Summary

Makes RepForge's Health Connect export match what the Health Connect API actually models, instead of the minimal per-set segment mapping that shipped before.

• Better segment types for generic lifts. Exercises with no dedicated Health Connect segment type (push-ups, dips, cable flies, barbell rows, shrugs, calf raises, tricep pushdowns, skull crushers, face pulls, rear delt flies, T-bar rows, seated cable rows, close-grip bench) now map to weightlifting instead of the generic otherWorkout catch-all.
• Real exercise names + numbered sets in the notes. Health Connect segments carry no per-exercise label, so the session notes field now reads e.g. Bench Press: 1) 60kg × 10, 2) 72.5kg × 8 for every exercise in the workout, alongside the user's own notes.
• Explicit rest segments. Each set becomes a correctly-sized work segment (from its recorded duration, or estimated from reps), and gaps of 30+ seconds between sets become real rest segments — instead of rest time being silently absorbed into the lift as before.
• Survives devices below Health Connect SDK Extension 21. Segment weight requires a newer Health Connect Mainline module; below that threshold the write used to fail the entire session (reps, segments, everything). Now it retries once without weight and remembers the device's capability for the rest of the app session, so the workout still syncs — just without the kg numbers — on older devices.
• Assisted-bodyweight exercises (pull-ups, chin-ups, dips, push-ups) report the actual load moved, not the machine assistance amount, in both the segment weight and the notes text.

User-level impact

Workouts synced to Health Connect now show up with real exercise names, numbered sets, and an accurate work/rest breakdown in any app that reads Health Connect (e.g. Google Fit), instead of one blended segment per set with no labels. People on older phones that can't store per-set weight get their full workout synced instead of the sync silently failing.

Test plan

• Full suite: 1089/1089 passing, flutter analyze clean
• New unit tests cover: segment type remapping, notes formatting (including bodyweight and truncation), rest-segment boundaries (including a regression test for a set landing exactly on the session start/end), the weight-fallback retry state machine, and every buildHcSegments test now also constructs a real ExerciseSessionRecord to verify Health Connect's own validation accepts the output — not just a hand-rolled approximation of it
• Manual on-device verification (Health Connect / Google Fit) — not done in this session, no device available

Walkthrough

Changes

The PR centralizes Health Connect session construction, adds formatted exercise notes, caches exercise names for synchronization, and retries writes without segment weights when unsupported.

Health Connect workout session sync

Layer / File(s)	Summary
Session segment and note builders workout-logger/lib/services/utils/hc_session_builder.dart, workout-logger/test/services/hc_session_builder_test.dart	Adds helpers for segment mapping, timed work and rest segments, weight handling, exercise notes, truncation, and comprehensive validation.
Health Connect write flow workout-logger/lib/services/interfaces/health_connect_service_interface.dart, workout-logger/lib/services/health_connect_service.dart, workout-logger/test/services/health_connect_service_test.dart	Passes exercise names to session sync, delegates construction to shared helpers, and retries without weights after UnsupportedOperationException.
Exercise-name resolution and sync wiring workout-logger/lib/services/managers/health_sync_manager.dart, workout-logger/lib/main.dart, workout-logger/test/*, workout-logger/test/test_utils/*	Loads and caches exercise names from storage, passes them to Health Connect, wires storage into HealthSyncManager, and updates test doubles for the expanded method signature.

Merge Risk: 🔵 Low · up to 09e76

Overlapping workout syncs can perform redundant exercise-name storage reads. Exports still succeed, but sharing the pending lookup avoids unnecessary work.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Share the in-flight exercise-name load.

syncSession is fire-and-forget, so concurrent calls can reach _resolveExerciseNames while getAllExercises() is pending. Each call sees a null _exerciseNames cache and starts a separate full read. Store and share an in-flight Future<Map<String, String>>, and clear it after completion so a failed load can retry. Add a test that holds getAllExercises() pending and verifies two syncSession calls perform one read.
