Minor Changes

• #15008 35c87e9 Thanks @skepticfx! - Adds the ability to find container instances by exact ID or name

  wrangler containers instances <application_id> --search <instance_id_or_name> now searches every page and returns exact matches in human-readable or JSON output. JSON returns a top-level array, including an empty array when there is no match, while human-readable output prints a no-match message. If multiple instances have the same exact name, every matching instance is returned.

• #15008 35c87e9 Thanks @skepticfx! - Add explicit pagination to container instance JSON output

  Use wrangler containers instances <application_id> --json --per-page <size> to return one page with machine-readable result_info, then pass its next_page_token to --page-token to retrieve the next page. Plain --json remains backward-compatible: it requests the complete list and returns the existing top-level array.

Patch Changes

• #15013 8cf78c8 Thanks @dario-piotrowicz! - Update undici from 7.28.0 to 7.29.0

• #15015 a60ff4d Thanks @nickpatt! - Cut the per-request cost of local observability capture

  Every tail event was written to the trace store as its own Durable Object call, so a request paid two or three round-trips per span. On a module-heavy app under the Vite plugin that dominated dev request latency. Rows are now buffered and written in batches, taking a request from roughly thirty calls to three.

  Work in progress still shows up as it happens: the root span is written immediately, console logs and exceptions as they arrive, and a span's completion is written on the next event once 100ms has passed. An invocation that goes completely quiet writes nothing further until it ends, since the flush is driven by tail events rather than a timer.

  The Vite plugin's own router, asset and proxy workers are also no longer captured. Their traces were noise the Observability views already hid, and skipping them cuts the spans recorded per request — a side benefit being that a trace's root is now your Worker rather than __router-worker__.
