04-06-02: Save error handling & retry logic

- Added specific error type differentiation:
  * Network errors → 'Anslutning misslyckades'
  * Validation (400) → 'Ogiltiga ändringar'
  * Auth (401/403) → 'Saknar behörighet'
  * Server (500+) → 'Serverfel'
  * Generic fallback messages

- Implemented retry tracking:
  * retryCount state for monitoring attempts
  * lastSavePayload storage for potential retry (future feature)
  * Console logging with context for debugging

- Enhanced error handling:
  * getErrorMessage() function for error classification
  * Comprehensive error logging with workout/exercise context
  * Draft preserved on all error types (no data loss)

- Improved UI/UX:
  * Error banner with specific, actionable messages
  * 'Försök igen' button with retry tracking
  * Sync status feedback (idle/saving/saved/error)
  * Success checkmark animation (2s duration)
  * Spinner animation during save

- CSS Enhancements:
  * @keyframes spin for loading spinner
  * @keyframes slideInCheckmark for success feedback
  * Mobile-responsive error banner (flex column on <480px)
  * Smooth animations for state transitions

Tests: npm run build ✓ (no syntax errors)

-# CLAUDE.md — Agent Development Guidelines
-
-This is the foundation for developing Claude agents and autonomous systems in the Gravl ecosystem.
-
-## Core Principles
-
-### 1. Autonomy with Verification
-- Agents execute tasks independently (autonomy)
-- **Always verify results** after delegation (no hallucinations)
-- Verification pattern: `git status`, `git log`, `ls`, diff before checkpoint update
-- Never report completion without checking actual work
-
-### 2. Checkpoint-Based Self-Monitoring
-All long-running tasks use checkpoint files:
-
-```json
-{
-  "lastRun": "2026-03-02T08:00:00Z",
-  "status": "completed|blocked|interrupted|error",
-  "result": "Summary of work",
-  "nextCheck": "What to do next"
-}
-```
-
-**Recovery logic:**
-- If `lastRun > 60min` OR `status ≠ "completed"` → trigger recovery
-- Log recovery attempts to help debugging
-- Use simple JSON for checkpoint files (no complex parsing)
-
-### 3. PM (Project Manager) Autonomy
-The Gravl PM agent:
-- Plans sprints/phases autonomously
-- Spawns specialized agents (frontend-dev, backend-dev, etc.)
-- Verifies their work before checkpoint completion
-- Reports progress to Telegram (not silent failures)
-- Timeout: 15 minutes (900s) per cron cycle
-
-### 4. Generalized Agents (Reusable)
-**Never create project-specific agents.**
-
-Use generalized agents instead:
-- `frontend-dev` — React/CSS specialist
-- `backend-dev` — Node.js/PostgreSQL specialist
-- `architect` — System design
-- `reviewer` — Code review
-- `browser-tester` — E2E testing + QA
-
-These are in `~/clawd/claude-agents-skills/agents/` and symlinked to `~/clawd/agents/`.
-
-### 5. Single Source of Truth
-All skills and agents live in ONE central repo:
-- **Hub location:** `~/clawd/claude-agents-skills/`
-- **Symlinks from:** `~/clawd/skills/` and `~/clawd/agents/`
-- **Commit everything to hub repo**
-- This enables sharing, versioning, and collaboration
-
-## Development Workflow
-
-### Adding a New Agent
-
-1. Create in hub: `~/clawd/claude-agents-skills/agents/my-agent/`
-2. Write `SOUL.md` (agent definition + personality)
-3. Optional: Add `README.md`, scripts, config
-4. Symlink automatically created: `~/clawd/agents/my-agent → hub/agents/my-agent`
-5. Commit to hub repo
-
-### Adding a New Skill
-
-1. Create in hub: `~/clawd/claude-agents-skills/skills/my-skill/`
-2. Write `SKILL.md` (how to use it)
-3. Add code/scripts as needed
-4. Symlink automatically created: `~/clawd/skills/my-skill → hub/skills/my-skill`
-5. Commit to hub repo
-
-### Verification Pattern (CRITICAL)
-
-After any subagent completes work:
-
-```bash
-# 1. Check git status
-git status
-
-# 2. Verify files changed
-git log --oneline -3
-
-# 3. Inspect actual changes
-git diff HEAD~1
-
-# 4. THEN update checkpoint
-echo '{"status":"completed",...}' > checkpoint.json
-```
-
-**This prevents hallucination bugs** where agents claim work they didn't do.
-
-## Communication
-
-### Report-Only Pattern
-- PM drives autonomously
-- Silence = approval (no blocking)
-- Only report at milestones or blocking issues
-- Use Telegram for delivery (channel: telegram)
-
-### Cron Jobs (3 active)
-| Job | Schedule | Timeout | Checkpoint |
-|-----|----------|---------|-----------|
-| Gravl PM | Every 30m | 15 min | `/workspace/gravl/.pm-checkpoint.json` |
-| Vietnam Flights | Daily 09:00 | 2 min | `~/.checkpoint-vietnam-flights.json` |
-| System Updates | Daily 10:00 | 5 min | `~/.checkpoint-system-updates.json` |
-
-All use explicit `"channel: telegram"` for Telegram delivery.
-
-## Code Conventions
-
-See `CODING-CONVENTIONS.md` for:
-- Frontend (React, CSS)
-- Backend (Express, PostgreSQL)
-- Database (schema, migrations)
-- Testing (Playwright, E2E)
-
-## Repository Structure
-
-```
-/workspace/gravl/
-├── frontend/          # React app
-├── backend/           # Node.js API
-├── db/                # Database setup

-├── CLAUDE.md          # This file (agent guidelines)
-└── .gitignore         # Excludes planning docs, node_modules
-```
-
-## Local-Only Files (Not in Git)
-
-These stay on disk but are excluded from `.git` via `.gitignore`:
-- `.planning/` — research, requirements, roadmap
-- `TODO.md` — task tracking
-- `frontend/tasks/` — feature tasks
-- `docs/plans/` — planning notes
-
-This keeps the repo clean while preserving your planning work locally.
-
-## Key Decisions
-
-1. **Generalized agents over project-specific** — More reusable, easier to maintain
-2. **Single hub repo** — Centralized versioning + easy sharing
-3. **Symlinks for discovery** — OpenClaw finds skills/agents automatically
-4. **Verification protocol** — Prevents hallucination bugs
-5. **Checkpoint-based recovery** — Self-healing cron jobs
-6. **Telegram for delivery** — Explicit channel to avoid missed messages
-
-## For the PM Agent
-
-The Gravl PM uses this playbook:
-
-1. **Plan phase** → Identify tasks, delegate to specialized agents
-2. **Execute phase** → Spawn agents, monitor progress
-3. **Verify phase** → Check git status, diffs, logs (NO HALLUCINATIONS)
-4. **Report phase** → Send Telegram update with result or blocking issue
-5. **Checkpoint phase** → Update checkpoint.json with status + nextCheck
-
-PM runs every 30 minutes autonomously. No human approval needed unless blocked.
