P1b's pure half (docs/RUST.md). Three pieces, all testable with no
widget in sight:
- `event_model::Event::ToolEnd` gains `is_error`, read from the CLI's own
`tool_result` field by both the live translator and the import replay
(`import::tool_result_is_error`, one reader so the two cannot disagree
about the same conversation). Without it a result is all a card has,
and a broken call draws exactly as confidently as one that worked --
the missing state, not a wrong one. `#[serde(default)]`, so an older
transcript reads back as "not reported to have failed".
- `client_core::transcript_fold::ToolState`: Running, Deciding,
Succeeded, Failed, NoResult. The pair it exists for is the last two
against Succeeded-with-empty-output -- a call that printed nothing and
a call whose result never arrived leave the same empty string, and only
the session's status separates "still going" from "nobody found out".
- `client_core::tool_summary::parse_tool_input` and
`client_core::durations`: `ToolInput.kt`'s subject/description/timeout
split and `Durations.kt`'s span formatting, ported with their tests.
The echo driver's three-call run now has a failing middle call, so the
failed appearance is reachable from `ui-sandbox.sh` at all.

The merge that brought main into rustify added Event::LimitReached to the
server's drivers, but on this branch the enum lives in event-model, which
the merge left without it, so ai-server (and ui-sandbox.sh) did not build.
Definition copied from main's driver.rs; the fold mirrors TranscriptItems.kt's
LimitNote; the iris row shows the epoch until P1 brings a time formatter.

The event-model commit picked up its build directory because there was
no gitignore entry for it -- server/target/ is listed explicitly rather
than a blanket target/, and the new crates need the same line each.

RUST.md's recommendation item 1 starts here: Event, QuestionOption,
SessionStatus, ImageRef, AttachmentRef, SeqEvent, context_tokens and
context_after move to a new event-model crate so a future Rust client
shares one definition with server/ instead of Events.kt's hand-kept
mirror. session/driver.rs and session/transcript.rs re-export
everything they used to define, so nothing downstream of either
module changed.
cargo test (127 passed), clippy --all-targets and fmt clean in both
server/ and event-model/.
