fix(cli): realign remote mode with the current v2 API (#759)

Remote mode had drifted from the v2 contract in three ways.

Two commands printed different columns depending on which backend
answered, contradicting the rule that an operation returns the same
shape in both modes. `maple metrics` passed the v2 resource straight
through (`name`, `service_name`, `data_point_count`) where local mode
returns the warehouse's `ListMetricsOutput` (`metricName`,
`serviceName`, `dataPointCount`); `maple timeseries` and `maple
breakdown` emitted `timestamp`/`group`/`avgDurationMs` against local's
`bucket`/`groupName`/`avgDuration`. Both now map onto local mode's row
shape. Neither was typechecked — the local side goes through the
untyped executor — so a test now pins the column names.

`maple error <fingerprint-hash>` refused remotely on the grounds that
v2 had no way in from a fingerprint hash. `/v2/error_issues` has taken
a `fingerprint_hash` filter since 0432f69, so the command now runs
remotely: fingerprint to issue, issue detail for the timeseries and
sample traces, then a per-trace fetch for the span count, services and
root span name the sample does not carry. It reads triage issues, not
raw error events, so a fingerprint no sweep has turned into an issue
fails with that reason rather than showing an empty page.

Trace search had a latent silent drop: the span-name guard let a
`--root-only` call through to a filter that never included `span_name`.
No such flag exists, so the branch was unreachable, but the refusal was
also wrong about why — v2 matches a span name exactly and returns root
summaries, where `--span-name` means a substring match over spans.

The remaining refusals were re-checked against the live contract and
still hold: attribute discovery, sorting trace search by duration, a
combined operation ranking, window comparison, raw SQL and `--offset`.
Their wording, and the local-mode and migration docs, cited an
`erris_…` issue id; the prefix is `iss_`, and the real blocker for
`maple errors` is that one issue per fingerprint cannot say how many
services an error spans.

/etc/otel/docker-config.yaml, including transform/compose which promotes
compose.project/service from datapoint to resource attributes.

First publish under the mapletechlabs namespace. appVersion 0.1.5 -> 0.2.0.

feat(web): rebuild the session flow view on React Flow with category …

…icons (#621)

The flow tab drew its own scaled div canvas with per-lane SVG connectors;
it now hands the same hand-computed lane layout to @xyflow/react — the
split investigations/flow already uses — so pan, zoom and edge drawing
come from the shared canvas instead of a bespoke scroller. Nodes declare
their dimensions and handle spots up front, so edges draw on the first
frame (and under jsdom, which never runs a ResizeObserver pass).

The category dots become glyphs from the shared icon set — robot for
agent, sparkle for inference, gear for tool, a red cross for a failure —
in the node cards and the legend both, so the kind of work reads by
shape rather than by hue alone.

v0.0.20

fix(cli): recovery advice after an unclean shutdown now names a command that
works — no more pointing at a checkpoint that was never taken.

v0.0.18

fix(traces): the trace view now corrects for clock skew between services, so a
child span recorded outside its parent is drawn nested inside it (Jaeger-style
centring) with a 'clock skew adjusted' badge, instead of floating past the
parent on an over-wide axis.

v0.0.17

fix(local): pin the embedded chDB engine to UTC. On hosts outside UTC every
time window was skewed by the UTC offset, so recent traces were invisible and
stale ones looked current. Repairs existing stores too.

v0.0.16

fix(local): allow the Authorization header on local-mode CORS preflight.
Browser SDKs configured with an ingest key can now post OTLP to `maple start`
instead of being blocked in preflight.
