Track a _needs_autozoom flag per plot. Set True at startup, on
reconnect (clear_data), and when a trace is added or removed. In
_redraw, when the flag is set and visible data exists, fit the Y range
to the data (with 10% margin) then clear the flag — subsequent live
updates leave the user's manual Y zoom undisturbed.

Add PlotTooltip — a frameless child widget that appears next to the
mouse cursor whenever it moves over a plot. It lists each active trace
with a colored bullet, short name, and the nearest y-value (unit
appended). The tooltip is repositioned on every mouse-move event and
clamped to stay within the plot widget bounds. Hidden on mouse-exit and
on clear_data (reconnect).

Replace pg.DateAxisItem with a custom TimeAxisItem that formats ticks
as HH:MM:SS, eliminating locale-dependent day/date prefixes on the axis.
Add a per-plot date label (right-aligned in the control bar) that shows
the date range of the visible window — single date when the view stays
within one day, "YYYY-MM-DD – YYYY-MM-DD" when it spans midnight.

Server (network.py): send every record in diff mode starting from
prev={}, including the first — fixes history drop on new client connect.
Collect (collect.py): remove payload["_diff"] = True from live broadcast.
GUI client (gui_client.py): always call jay_merge_full in diff mode;
drop the _diff key check that gated reconstruction.
CLI client (client.py): fix `args.diff or True` guard that made --diff
irrelevant.

jay_merge_full/jay_merge_update mutates _state nested dicts in place.
The previously emitted dict(_state) was a shallow copy sharing those
nested dicts, so background-thread merges retroactively corrupted
already-emitted snapshots: timestamps were correct (strings are
immutable) but Y values all converged to the latest record's values.
Fix: emit copy.deepcopy(_state) so each snapshot is fully independent.

Server (collect.py --diff):
- History burst: first record sent full, subsequent as jay_diff_full diffs
- Live broadcast: each snapshot diffed against the previous one
- Diff payloads tagged with "_diff": true
Client (client.py --diff):
- Reconstructs full state via jay_merge_full before printing
GUI (Connector tab "Diff mode" checkbox):
- TcpReader.connect_to() accepts diff_mode; maintains _state dict
- Merges incoming diffs before emitting to Dashboard/Plot
- Checkbox state persisted to plot_settings.json
Both sides default to off; must be enabled consistently on server and client.
utils/__init__.py added so utils.jay_diff is importable as a package.

Replace direct _redraw() calls in PlotTab.update() with a 100 ms
single-shot QTimer. During a burst of incoming records (e.g. 500
history records on connect) only the data is accumulated; a single
redraw fires 100 ms after the last record arrives instead of once
per record (~4000 pyqtgraph redraws avoided).

Add PlotTab.clear_data() which resets _series and _units, then redraws.
Called in MainWindow._connect() before opening the socket so stale data
from a previous session never mingles with fresh history from the server.

Track the earliest timestamp across plotted traces (starting from None,
not cutoff) so setXRange uses the first real data point as the left
bound — no empty gap when data doesn't fill the full time window.

- Save host/port to plot_settings.json on connect; restore on startup
- Raise MAX_PLOT_POINTS from 200 to 2880 so 24 h of data is retained
even at 30 s polling intervals

Replaces the single global toolbar spinbox with one QSpinBox per plot,
placed between the '+' button and the trace chips. Each plot has an
independent 1–24 h window; values are persisted in plot_settings.json
under 'time_windows'.

A spinbox above the plot grid sets the visible x range for all 8 plots.
Data outside the window is excluded from each redraw; x axis is fixed to
[now - window, now]. Setting is persisted in plot_settings.json.

Color palette taken directly from nmea_client/gui/plot_widget.py:
- Background #1a1a2e / #12121e, borders #2a2a4a/#3a3a5e,
text #aaaacc/#ddddee, connected #4CAF50, error #F44336
- Trace colors: Material palette (blue, red, green, orange, …)
- Plot widget background overridden from "white" to #12121e
- pyqtgraph foreground set to #aaaacc

- Trace selection combos show short labels (_trace_label) with full key
stored as item data; width auto-adjusts to content (min 120 px)
- Extended plot grid from 4 to 8 (4×2) wrapped in QScrollArea
- Removed reset-zoom toolbar and cursor readout area

InfiniteLine was included in auto-range calculations, causing the view
to rescale on every cursor move. Add it with ignoreBounds=True in both
the initial setup and after each redraw.

- Replace static combo grid with a control bar above each plot:
add-trace dropdown + "+" button; active traces shown as colored chips with
"×" to remove (max 4 per plot)
- Save trace selection to ~/.config/we_monitor/plot_settings.json on every
change; restore automatically once matching signals arrive from the server
- Remove tiny tick-font overrides so axis labels are readable at default size
- Show received record count in the status bar

Removed the QScrollArea wrapper and fixed figure-height calculation.
FigureCanvasQTAgg now fills the tab with an Expanding size policy so
all 8 subplots fit in the visible area at 1920x1200 without scrolling.

create_connection(timeout=5) left a 5-second read timeout on the
socket. Any collection interval longer than 5 s caused recv() to
raise socket.timeout, which was caught as OSError and reported as
a lost connection. Switch to blocking mode with settimeout(None)
immediately after the connect handshake.

- Connector tab: host/port fields, connect/disconnect button, status
- Dashboard tab: live QTreeWidget of the full snapshot hierarchy;
physical values show value and unit in separate columns;
expand state preserved across refreshes
- Plot tab: matplotlib time-series subplots (2 columns) for every
physical {value, unit} field, scrollable, auto-layout on new keys
- TcpReader runs in a daemon thread and delivers messages via
Qt signals so the UI never blocks
