…w injected context

These tests reproduce #24067: Codex response_item context blocks and
question-reply envelopes, the Codex files-mentioned request prefix, and Claude
local slash-command wrappers and output leak into imported user messages.

Codex rollouts that record user events now import only those events, as
Codex's own history does, instead of deduping response copies by turn ID.
The typed request after "## My request for Codex:" is imported and titled.
Claude local slash commands import as typed and their local output is
dropped.

…dably

Paginated Codex rollouts have no user_message events, so onboarding import fell
back to response items and showed AGENTS.md and environment context. Completed
UserMessage items now count as user events. Answered-question envelopes import
as quoted Q&A like Codex shows them, and the request marker only strips a
prefix when it occupies a whole line.

Codex prompts that open with generated IDE, file or browser context end it
at the last request line; unwrapped prompts that quote the marker keep their
text.

…once

When the request marker repeats, either the generated context or the user's
request may quote it, so taking the last one could drop the user's text.

An image-only Codex prompt has no text, so with response copies suppressed
the turn vanished; it now imports as Codex's own [Image #n] placeholders.
Response-only prompts whose setup context is followed by the request line
are titled after the request again, and a prompt recorded as both a
user_message and a completed UserMessage imports once.

A rollout with any user event dropped every response-only user turn, so
legacy prompts resumed in a newer Codex lost their text and question
replies vanished. Response copies are now skipped only in turns that have
a user event.

Counting inline `images` selected their whole data URLs, which spent the
history budget and skipped screenshot-heavy rollouts; image-only prompts
now count local image paths only.

A user event with no text, such as an inline image alone, hid every
response copy in its turn, so an image-only conversation imported nothing.
Such events no longer stand in for their copies. An interrupted turn ends
without an assistant message, so its prompt merged into the next
event-backed turn and was hidden; turn_aborted and task_complete now end a
turn too.
