v0.10.0 — monitor log entry support (SUB 0x0A partial records)

Add full decode pipeline for 0x2C partial records from the device's event
list, representing continuous monitoring intervals where no threshold was
crossed.  These records appear interleaved with full triggered events in the
browse walk and were previously ignored.

minimateplus/models.py
- Add MonitorLogEntry dataclass: key, start_time, stop_time, serial,
  geo_threshold_ips, raw_header, duration_seconds property

minimateplus/protocol.py
- read_waveform_header() now returns (data_rsp.data, length) — full payload
  including the record-type byte at position 0 — instead of the sliced header.
  Callers that need the old slice use raw_data[11:11+length] as before.

minimateplus/client.py
- Add _decode_0a_partial_header(): auto-detects 9-byte (sub_code=0x10) vs
  10-byte (sub_code=0x03) timestamp format, handles 1-byte inter-timestamp
  gap, extracts serial via BE anchor and geo threshold via Geo: anchor.
- Add get_monitor_log_entries(skip_keys=None): browse walk (1E → 0A → 1F),
  decodes partial records, skips full records and already-seen keys.

minimateplus/__init__.py
- Export MonitorLogEntry

bridges/ach_server.py
- After get_events(), call get_monitor_log_entries(skip_keys=seen_keys) and
  save new entries to monitor_log.json in the session directory.
- Add _monitor_log_entry_to_dict() helper.
- Include monitor log keys in downloaded_keys for state persistence.

CLAUDE.md / CHANGELOG.md
- Document 0x2C partial record layout (timestamp format, ASCII metadata
  region, 1-byte gap edge case) confirmed from 4-11-26 MITM capture.
- Version bump to v0.10.0; update What's next.

+    """
+    A monitor log entry decoded from a SUB 0x0A (WAVEFORM_HEADER) response
+    whose first byte is 0x2C (partial record, recording mode = continuous
+    monitoring without a triggered event).
+
+    These are the "partial bins" that Blastware stores between triggered events.
+    Each entry represents one monitoring interval — the span of time during
+    which the unit was actively monitoring but no threshold crossing occurred.
+
+    Confirmed from 4-11-26 MITM capture analysis (2026-04-11):
+
+    Header layout (full response data[0:]):
+      data[0]    = 0x2C  (partial record type / data length in probe response)
+      data[1:5]  = 0x00 × 4
+      data[5:9]  = event key (4 bytes, big-endian hex)
+      data[9:11] = 0x00 × 2
+      data[11:]  = timestamp_start (9 or 10 bytes depending on recording mode)
+                   + timestamp_stop (same format)
+                   + separator (4–5 bytes, variable)
+                   + serial null-terminated (e.g. "BE11529\\0")
+                   + "Geo: X.XXX in/s\\0"  (trigger threshold string)
+
+    Timestamp format detection:
+      data[11] == 0x10  →  10-byte sub_code=0x03 (continuous) format
+      data[12] == 0x10  →  9-byte sub_code=0x10 (single-shot) format
+
+    In contrast to Event (triggered records, type 0x46), MonitorLogEntry
+    records do NOT have a waveform record (SUB 0x0C) or bulk waveform stream
+    (SUB 5A).  All available metadata is in the 0x0A header alone.
