Kpa-clawbot d43c95a4bb fix(ingestor): warn when TRACE payload decode fails but observation stored (closes #889) (#992) ...

## Summary

Closes #889.

When a TRACE packet's payload is too short to decode (< 9 bytes),
`decodeTrace` returns an error in `Payload.Error` but the observation is
still stored with empty `Path.Hops`. Previously this was completely
silent — no log, no anomaly flag, no indication the row is degraded.

This fix populates `DecodedPacket.Anomaly` with the decode error message
(e.g., `"TRACE payload decode failed: too short"`) so operators and
downstream consumers can identify degraded observations.

## TDD Commit History

1. **Red commit** `04e0165` — failing test asserting `Anomaly` is set
when TRACE payload decode fails
2. **Green commit** `d3e72d1` — 3-line fix in `decoder.go` line 601-603:
check `payload.Error != ""` for TRACE packets and set anomaly

## What Changed

`cmd/ingestor/decoder.go` (lines 601-603): Added a check before the
existing TRACE path-parsing block. If `payload.Error` is non-empty for a
TRACE packet, `anomaly` is set to `"TRACE payload decode failed:
<error>"`.

`cmd/ingestor/decoder_test.go`: Added
`TestDecodeTracePayloadFailSetsAnomaly` — constructs a TRACE packet with
a 4-byte payload (too short), asserts the packet is still returned
(observation stored) and `Anomaly` is populated.

## Verification

- `go build ./...` ✓
- `go test ./...` ✓ (all pass including new test)
- Anti-tautology: reverting the fix causes the new test to fail (asserts
`pkt.Anomaly == ""` → error)
