v0.58.0

Release Notes — v0.58.0

Major: Requests no longer die on an oversized body, and the free daily allowance reads as one

An ogcode turn that accumulated one screenshot per step used to hit one of the
gateway's hard size ceilings and fail with a terse 400, with no repair offered.
The ceiling is now applied against nginx's own 20 MiB limit, and a body that is
still over it is repaired by shedding the oldest image frames — tool-result
screenshots first, the user's own attachments last, each replaced in place with a
short note of what was removed — resending until it fits. A turn where no image
is left to drop says so plainly and asks for a shorter conversation instead of
retrying the same oversized body.

A 429 from the gateway can now also be the spent free daily allowance rather
than a plan budget: it refills with the UTC day, so it is reported as a
resumable wait whose reset time it names, classified ahead of the plan-budget
429.

Major: A finished turn no longer looks like it is still running tools

A loop that ended between writing an assistant message and running its tool
calls left those parts marked running, and every client and re-read treated the
turn as live — the "Running N tools" indicator, guidance mode, the running tool
list. The parts are closed at loop exit, and reconciled sessions repair parts
that already received a result by copying its ending so the panel states the
outcome instead of a generic one. The web side reads the live tool list only
while the session status is running, inspects only the tail assistant message,
and skips a call a user-side tool result already answered.

Minor: First-party analytics proxy, on by default

Capture, decide and log shipping now go through a.ogcode.in instead of
*.posthog.com, avoiding domain-level blockers, and log shipping is on unless
explicitly turned off or DO_NOT_TRACK is set.

Minor: Settings navigation

The settings sidebar is resizable, folds to a 48 px icon rail, and the wordings
for resizing and collapsing are clarified.
