Richard FeldmanandBennet Bo Fenner fa4ae33e20 Add telemetry for context compaction (#58928)
Adds an `"Agent Compaction Completed"` telemetry event that fires for
both threshold-triggered auto-compaction and the manual `/compact`
command (both already behind the `handoff` flag). The event records the
model, model provider, thinking effort, the model's context window size,
the token counts immediately before and after compaction, whether the
compaction succeeded/failed/canceled (with the error string on failure),
the user's configured auto-compaction threshold (both the raw form and
the resolved absolute token count), whether auto-compaction is enabled,
and the number of retries.

Both compaction paths funnel through `stream_compaction`, so a
`CompactionTelemetry` snapshot is captured when a compaction starts and
stashed on the thread. On success, emission is deferred until the next
completion request reports usage, so `tokens_after` reflects the real
post-compaction context size rather than an estimate (we have no
token-counting API, and it's safe to assume a compaction is always
followed by another request). On failure or cancellation the event fires
immediately with no `tokens_after`. Retries are accumulated across
attempts so a single logical compaction produces exactly one event.

While wiring up retry counting I noticed the existing auto-compaction
retry path in `run_turn_internal` never increments `attempt`, so a
repeatedly-failing retryable compaction could retry without bound. I
left that behavior untouched as out of scope, but the new `retries`
field will surface it if it happens.

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
