0.0.38

Added

• ekr mcp-http and ekr view take --metrics, which serves GET /metrics in the Prometheus
  text exposition format, and --request-log <path> (- for standard error), which writes one
  ekr.request-log/1 JSON line per request. Both count each read at their dispatch by its wire
  name and outcome under one set of names: ekr_read_requests_total{tool,outcome},
  ekr_read_duration_seconds{tool}, ekr_read_result_bytes{tool}, ekr_read_in_flight,
  ekr_store_head_revision and ekr_store_query_errors_total{tool}, so one read through either
  server moves the same series. A log line carries the request's X-Request-Id and
  traceparent when they are well formed, generated ones otherwise, and never an argument, a
  result, document content or a credential. /metrics is admitted as every other path is and
  answers 404 without the option (ekr.views.ReaderMetricName, ekr.views.RequestLogV1,
  ekr.cli.ReaderTelemetryOptions).
• ekr.node-matches/3, a search that ranks a whole name or alias first whatever its case
  (story:search-match-kinds). Under ekr.node-matches/2 a case-exact match comes before a
  case-folded one, so a node whose whole name is the text in another case ranked below every node
  holding the text case-exactly inside a longer name or alias, and a reader of the first few
  matches missed it. /3 matches the nodes /2 matches, with the same type, from and to, and
  names each match's kind — WholeName, WholeAlias, Prefix, Substring or Words — and
  folded, whether it matched only after lowercasing. Matches rank by kind, then case-exact
  before case-folded, then (with a window) newest first, degree and id; meta.whole_total
  counts the whole matches before limit. ekr view's /search and the session verb search
  answer it with format=ekr.node-matches/3 (--format), and the SDK reads it as
  Reader::search_v3, NodeMatchesV3. ekr.node-matches/1 and /2 answer the bytes they did.

Changed

• The search tool of ekr mcp answers ekr.node-matches/3 when no format is named (it
  answered /2); name ekr.node-matches/2 or /1 for the earlier documents.
