Addresses intermittent connection timeout errors on mobile networks by
adding automatic retry with exponential backoff for transient failures.

Key changes:
- Add RetryInterceptor with configurable max retries and backoff delay
- Prevent POST receiveTimeout retries to avoid duplicate comments/votes
- Reduce connect timeout from 30s to 10s with 2 retries (better UX)
- Add constructor validation (assertions) for interceptor params
- Refactor coves_auth_service to use nullable Dio pattern
- Add comprehensive documentation for restoreSession error handling

Safety: POST + receiveTimeout is NOT retried because the server may
have already processed the request. Other timeout types (connection,
send) are safe to retry as the request never reached the server.

Multi-feed state management with security hardening:

- FeedState model with sentinel copyWith pattern for nullable field clearing
- MultiFeedProvider with per-feed state and cross-session security guards
- FeedPage widget with pull-to-refresh on empty state
- FeedScreen auth sync and lazy feed loading
- Comprehensive tests for new architecture

Fixes:
- copyWith can now clear nullable fields (cursor, error, lastRefreshTime)
- Cross-session data leaks prevented via DID comparison
- Empty feed states are now refreshable
- PageController syncs with auth state on sign-out
- For You tab loads on first access after sign-in

- Use cascade notation where appropriate (cascade_invocations)
- Put control body on separate line (always_put_control_body_on_new_line)
- Break long string to stay under 80 chars (lines_longer_than_80_chars)
- Apply dart format to all changed files

Refactors FeedScreen to work with MultiFeedProvider and adds several
UX and reliability improvements:

PageView for feed switching:
- Authenticated users can swipe between Discover and For You
- Unauthenticated users see only Discover (no PageView)
- Per-feed ScrollControllers with position restoration

Auth state synchronization:
- Listens to AuthProvider changes
- Jumps PageController to page 0 on sign-out to match provider state
- Prevents tab/page mismatch after re-authentication

Lazy feed loading (_ensureFeedLoaded):
- Triggers initial load when switching to an unloaded feed
- Handles case where user signs in after app start and taps For You
- Called from both tab tap and swipe navigation

This fixes issues where:
- For You tab showed empty state after signing in mid-session
- PageController stayed on page 1 after sign-out while provider
switched to Discover, causing misalignment on re-auth

Extracts feed rendering logic into a reusable FeedPage widget that
handles all feed states:

- Loading: Centered CircularProgressIndicator
- Error: User-friendly message with Retry button
- Empty: Contextual message based on auth state
- Posts: ListView.builder with pagination support

Key improvements:
- Empty state now wrapped in RefreshIndicator with CustomScrollView
and SliverFillRemaining, allowing pull-to-refresh when feed is empty
- Error messages are user-friendly (maps technical errors to readable text)
- Loading more indicator at list bottom during pagination
- Proper scroll controller integration for infinite scroll

This fixes an issue where unauthenticated users with an empty Discover
feed had no way to retry without restarting the app.

Replaces FeedProvider with MultiFeedProvider that manages separate
state for Discover and For You feeds. Key improvements:

Architecture:
- Per-feed state management using Map<FeedType, FeedState>
- Centralized _fetchFeed helper eliminates code duplication
- Auth-aware feed switching (For You requires authentication)
- Minute-based time updates for relative timestamps

Security (cross-session data leak prevention):
- Captures session DID before fetch to detect auth changes
- Discards For You responses if session changed during fetch
- Guards both success and error paths to prevent stale data
- Removes feed state entirely on session change (not copyWith)

This prevents scenarios where:
- User signs out during fetch → old data reappears
- User A signs out, User B signs in → User A's feed shown to B
- Fetch errors after sign-out → stale posts restored

Introduces FeedState as an immutable state container for per-feed data
(Discover and For You feeds). Key features:

- Holds posts, cursor, loading states, error, scroll position, and
last refresh time
- Uses sentinel pattern for copyWith to distinguish "not provided"
from "explicitly set to null" for nullable fields (cursor, error,
lastRefreshTime)
- Enables proper clearing of fields on refresh/error recovery

The sentinel pattern fixes a bug where nullable fields couldn't be
cleared back to null through copyWith - critical for pagination
cursor handling when reaching the end of a feed.

Move provider initialization from postFrameCallback to didChangeDependencies
for synchronous access before first build. Create ScrollController with
initialScrollOffset set to cached position, eliminating the visible flash
from loading → content at top → jump to cached position.
