Add specific fetchers for HRV, Body Battery, and Intensity Minutes
to enable real biometric data collection from Garmin Connect API.
Functions added:
- fetchHrvStatus(): Returns "Balanced", "Unbalanced", or "Unknown"
- fetchBodyBattery(): Returns current BB and yesterday's low value
- fetchIntensityMinutes(): Returns 7-day rolling sum of activity
All functions gracefully handle API failures with safe defaults.
Test count expanded from 14 to 33 covering all scenarios.

Implement comprehensive test coverage for five library modules:
- encryption.test.ts (14 tests): AES-256-GCM encrypt/decrypt round-trip,
ciphertext format validation, error handling, key padding/truncation
- nutrition.test.ts (17 tests): seed cycling by cycle day, carb ranges
by phase, keto guidance by phase, seed switch alert on day 15
- garmin.test.ts (14 tests): token expiry checks, days until expiry
calculation, API fetch with auth headers, error handling
- email.test.ts (14 tests): daily email composition with biometrics,
nutrition guidance, period confirmation emails, null value handling
- ics.test.ts (23 tests): ICS format validation, phase events with
emojis, warning events on days 22/25, cycle length handling
Total: 82 new tests bringing project total to 254 passing tests.

Add authentication infrastructure for protected routes:
- withAuth() wrapper for API route handlers (src/lib/auth-middleware.ts)
- Next.js middleware for page protection (src/middleware.ts)
withAuth() loads auth from cookies, validates session, and passes
user context to handlers. Returns 401 for unauthenticated requests.
Page middleware redirects unauthenticated users to /login, while
allowing public routes (/login), API routes (handled separately),
and static assets through.
Tests: 18 new tests (6 for withAuth, 12 for page middleware)
Total test count: 60 tests passing

Add authentication utilities to pocketbase.ts for server-side auth:
- createPocketBaseClient() - factory for fresh instances per request
- isAuthenticated(pb) - checks authStore validity
- getCurrentUser(pb) - returns typed User from authStore
- loadAuthFromCookies(pb, cookies) - loads auth from Next.js cookies
Includes 9 unit tests covering all auth state scenarios and cookie loading.
This unblocks P0.2 (auth middleware) and all downstream API/page work.

Add getDecisionWithOverrides() function that checks manual overrides
before algorithmic rules. Overrides are applied in priority order:
flare > stress > sleep > pms, and all force REST status.
Includes comprehensive test suite with 24 tests covering:
- All 8 algorithmic priority rules
- Override type behaviors
- Override priority enforcement
- Empty override fallthrough to algorithmic rules
