Two improvements to DM functionality:
1. Removed DM button from message blocks in channel view
- Users should use the DM page directly instead
- Cleaner UI without redundant buttons
2. Filter only CLI (client) contacts in DM dropdown
- Added filter_types parameter to parse_contacts()
- get_contacts_list() now returns only CLI contacts
- Repeaters (REP), rooms (ROOM), and sensors (SENS) are excluded
- You can't send DMs to repeaters anyway!
Updated README.md to reflect these changes.

Changed DM approach from conditional button visibility to showing all
available contacts directly in the DM page dropdown. This provides better
UX and performance.
Changes:
- Reverted conditional DM button visibility in app.js (button always shows)
- Removed contacts loading from main page (app.js)
- Added loadContacts() function to dm.js to fetch contacts from API
- Modified populateConversationSelector() to show:
1. Existing conversations (with history) first
2. Separator: "--- Available contacts ---"
3. All contacts from device who aren't in conversations yet
- Users can now start new DM conversations with any contact
- Updated README.md with new DM workflow description
Benefits:
- Simpler and more intuitive UX
- Better performance (no checks on every message)
- Users can proactively start conversations
- Clear visibility of who's available for DM

Previous regex stopped at first space, causing names like "daniel5120 🔫"
to be parsed as just "daniel5120", breaking DM button visibility checks.
Changed parsing logic to split by 2+ consecutive spaces (column separator
in meshcli output) and extract full contact name before type column.

The DM button is now only shown for users who are in the device's contacts
list, ensuring that direct messages will actually be delivered. This prevents
users from attempting to send DMs to recipients who cannot receive them.
Changes:
- Added parse_contacts() and get_contacts_list() functions to cli.py for parsing
meshcli contacts output
- Created /api/contacts endpoint to retrieve contact names from device
- Modified frontend app.js to fetch and cache contacts list on page load
- Updated createMessageElement() to conditionally render DM button only when
sender is in contacts list
- Updated README.md with note about DM button visibility requirement

Fix channel message sender name display. In meshcore-cli 1.3.12, the 'name'
field in SENT_CHAN entries now contains the channel name instead of the
sender's device name. Update parser to use the 'sender' field instead.
Before: Sent messages showed "channel 0" as sender
After: Sent messages correctly show "MarWoj" (actual sender name)
This change is consistent with the SENT_MSG parsing for Direct Messages.

Remove workaround for meshcore-cli 1.3.11 bug where SENT_MSG contained
sender name instead of recipient. Now using native SENT_MSG entries from
.msgs file with correct recipient and sender fields (requires meshcore-cli >= 1.3.12).
Changes:
- Add _parse_sent_msg() to parse SENT_MSG from .msgs file
- Update read_dm_messages() to process both PRIV and SENT_MSG from .msgs

Benefits:
- Single source of truth (.msgs file only)
- Simpler codebase (-95 lines)
- No custom workarounds
- Better data consistency

Root cause: Multiple concurrent meshcli calls were fighting for USB access,
causing "Protocol error" and 504 Gateway Timeouts.
Changes to meshcore-bridge:
- Add threading.Lock to serialize meshcli subprocess calls
- Prevent concurrent USB access that causes OSError [Errno 71]
- Reduce DEFAULT_TIMEOUT from 30s to 10s
- Add detailed logging for lock acquisition and release
Changes to main API:
- Implement 30s cache for get_channels() to reduce USB calls
- Cache invalidation after channel create/join/delete operations
- Use cached channels in /api/channels and /api/messages/updates
- Reduce HTTP timeout from 30s to 12s (10s bridge + 2s buffer)
Impact:
- Eliminates race conditions when page loads (multiple API calls)
- Prevents USB port conflicts and protocol errors
- Faster response times due to caching
- No need for manual USB resets after container restarts

- Implement fallback mechanism to ensure Public channel always exists
- Fix race condition by loading channels before setupAutoRefresh()
- Add proper validation for API responses and channel data
- Improve error handling with detailed logging
- Prevent checkForUpdates() from running before channels are loaded
This fixes the recurring issue where the channel dropdown would
randomly become empty, especially visible on mobile devices.

Replaces the blind 60-second refresh with a smart polling system that only updates the UI when new messages actually arrive.
Key improvements:
- Lightweight update checks every 10 seconds (vs full refresh every 60s)
- Chat view refreshes only when new messages appear on active channel
- Notification bell with global unread count across all channels
- Per-channel unread badges in channel selector (e.g., "Malopolska (3)")
- Last-seen timestamp tracking per channel with localStorage persistence
- Bell ring animation when new messages arrive
Backend changes:
- New /api/messages/updates endpoint for efficient update polling
- Returns per-channel update status and unread counts
Frontend changes:
- Smart auto-refresh mechanism with conditional UI updates
- Unread message tracking system with localStorage
- Notification bell UI component with badge
- Channel selector badges for unread messages
- CSS animations for bell ring effect
This dramatically reduces network traffic and server load while providing better UX through instant notifications about activity on other channels.

Fix critical JavaScript error that prevented channel selector from working:
- Add null check for selectedOption before accessing .text property
- Prevents "can't access property 'text', undefined" error at line 106
- This error occurred when selector options were being rebuilt
Additional cleanup:
- Remove duplicate escapeHtml() function definition
- Add detailed console logging to loadChannels() for debugging
Root cause: When populateChannelSelector() clears and rebuilds options,
the change event can fire with an invalid selectedIndex, causing
e.target.options[e.target.selectedIndex] to return undefined.

Fix issue where channel selector would show empty or missing channels
after auto-refresh. The populateChannelSelector() function was clearing
all options but not rebuilding them from API data correctly.
Changes:
- Rebuild entire dropdown from API response (including Public channel)
- Use currentChannelIdx from global state for selection
- Fallback to Public (index 0) if saved channel no longer exists
- Remove unused variable (IDE warning fix)
Bug: Channel selector showing empty after first auto-refresh
Root cause: API returns ALL channels including Public at index 0,
but the function was clearing all options and not adding them back.

Fixed mobile browser viewport height issues where status bar and hint text were hidden:
CSS changes:
- Use 'height: 100dvh' (dynamic viewport height) for mobile browsers
- Fallback to '100vh' for older browsers
- Added 'min-height: 0' to main flex container (critical for flex children)
HTML changes:
- Added 'viewport-fit=cover' to meta tag (notched displays)
- Improved flexbox structure in index.html
- Added inline 'min-height: 0' on flex-grow-1 row (prevents overflow)
The 'dvh' unit dynamically adjusts to browser chrome (URL bar) visibility,
preventing layout shifts when scrolling on mobile. The min-height: 0 fix
ensures flex children properly shrink when needed.
This should fix the issue where bottom status bar disappears on mobile
and top navbar disappears after sending a message.

- Better vertical space utilization on small screens
This should make the status bar visible on mobile devices and improve overall usability on phones.
