feat(log-list): add --trace flag to filter logs by trace ID (#329)

Add `--trace` flag to `sentry log list` that scopes the query to a
specific trace ID.

When `--trace` is given, the command uses the dedicated trace-logs
endpoint (`/organizations/{org}/trace-logs/`) instead of the
project-scoped events endpoint, since the Explore/Events logs API does
not support trace ID filtering in query syntax. This means only org
resolution is needed — the positional target is treated as an org slug,
not an org/project pair.

### Changes
- `--trace` flag with 32-char hex validation on `sentry log list`
- Works in both single-fetch and `--follow` streaming modes
- Trace follow mode polls the trace-logs endpoint and deduplicates by
`timestamp_precise`
- Refactored `writeLogs()` to accept both `SentryLog` and `TraceLog` via
shared `LogLike` type
- Trace-logs mock route + 5 E2E tests

### Usage
```bash
sentry log list --trace abc123def456abc123def456abc123de
sentry log list myorg --trace abc123def456abc123def456abc123de
sentry log list myorg --trace abc123def456abc123def456abc123de -f
sentry log list myorg --trace abc123def456abc123def456abc123de --json
```

Closes #317
