v1.26.1

Patch Changes

• #438 35ab9ea Thanks @charliecreates! - Align MCP tool response helpers with SDK CallToolResult typing by
  replacing the loose custom response interface, narrowing helper content to
  SDK TextContent[], and ensuring JSON responses always emit string text.

• #436 f1b6018 Thanks @charliecreates! - Add a shared bounded TTL async cache utility and migrate exercise template
  catalog caching in search-exercise-templates to use it. This keeps cache
  behavior consistent (TTL, LRU bound, refresh invalidation, and in-flight
  request de-duplication) and adds tests plus README documentation.

• #463 d5df6ca Thanks @chrisdoc! - Fix commitlint failing on Mergify batch merge commits in the merge queue.

• #434 59f95fe Thanks @charliecreates! - Deprecate CLI API key arguments by warning on stderr whenever
  --hevy-api-key=..., --hevyApiKey=..., or hevy-api-key=... is used.
  Keep backward compatibility for those flags while documenting HEVY_API_KEY
  as the recommended and secure configuration path.

• #474 12cf700 Thanks @chrisdoc! - Fix missing OTEL_COLLECTOR_TOKEN in the Release workflow build step.

  The Release workflow built the npm package without passing the
  OTEL_COLLECTOR_TOKEN secret, so the published package had an empty
  collector token. This caused the OTLP exporter to be skipped at
  runtime (the if (collectorToken) guard in telemetry.ts), meaning
  no traces or metrics were sent to the OTel Collector.

• #439 ca182f6 Thanks @charliecreates! - Add mocked integration coverage with nock and run mocked integrations on every
  PR while keeping live integrations optional behind HEVY_API_KEY.

• #431 b6fe3c0 Thanks @charliecreates! - Add CLI --help/-h and --version/-v flags that print output and
  exit before server startup, with unit test coverage for flag and default
  startup behavior.

• #423 8dfb593 Thanks @charliecreates! - Map common Hevy API error statuses to clearer MCP error messages and keep
  structured debug context with original HTTP details for troubleshooting.
