Closes docs/RUST.md's "client-core prerequisites for P1" box: the
cache-vs-server stitching TranscriptSource.kt does, and the
joinPages/healSplitMessage/adoptRun page-boundary healing
TranscriptItems.kt does, both ported into client-core with no UI
framework dependency.
Neither Kotlin file had a JVM unit test of its own, so the port used the
Kotlin source and AGENTS.md's "things that have bitten" paging incidents
as the spec instead of a test-for-test transcription. Both regressions
get a dedicated test: TranscriptSource::page refuses before == 0 before
touching the cache or the network (loadOlderPage's incident), and
adopt_run now runs on every page join rather than only the one where a
split call was found (the "one run drawn as two" incident).
fetch_transcript_lines (api.rs, additive) pairs each transcript line with
the exact server bytes via serde_json::value::RawValue rather than
re-serializing a parsed Value, so a cached line and a live SSE frame for
the same event agree byte-for-byte -- the fetch_transcript_page other
callers under iris/ depend on is untouched.
client-core: 85 -> 109 tests. cargo test/clippy --all-targets/fmt clean.

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.

Both desktop-app's app.rs and the new Android transcript client (RUST.md's
I5) need the same page-fold and live-stream resume-cursor logic; per
CODE_RULES's "write the logic once" it now lives in client-core alongside
fold_event/group_tool_runs instead of being duplicated. desktop-app calls
the shared functions; its own copies and their tests moved with them.
Also fixes a clippy::collapsible_if in config.rs's percent_decode, found
while re-running clippy after this change (let-chains are stable now).

A Rust client needs the same host/port/token an Android phone gets from
scanning an aiapp://enroll?... QR, so a desktop build can enrol from the
identical text pasted rather than a second format invented for it.

Two Java classes (MainActivity, NotificationService) hand their lifecycle
to a new android-shell crate built on client-core; client-core gains
notifications.rs (the /notifications SSE parse and attention_line, ported
from Notifications.kt). Packaged as a new app/shellApp Gradle module
rather than a rewrite of app/androidApp in place, so that module's working
Compose UI is untouched.
Both pass conditions held on the emulator: a notification arrived in
Android's drawer with the app closed, and a shared text share landed as a
real message in a sandbox session's transcript. Found and fixed three
real bugs along the way (a silently-wrong JNI signature from a generic
JObject parameter, a class-by-name lookup failing on this crate's own
background thread for lack of an app ClassLoader, and onStartCommand
opening two /notifications connections per enrollment -- the last a
latent bug in Notifications.kt itself). Full account, exact commands and
what was deliberately cut are in RUST.md's E3 box.

Ports the non-Compose half of app/.../TranscriptItems.kt (TranscriptItem,
foldEvent, runIdFor, settleReply, placePeerNote, splitRun) and
ToolRows.kt (TranscriptRow, groupToolRuns) into transcript_fold.rs, with
7 tests covering delta accumulation, settling, tool-run grouping, a
ToolEnd with no matching start, and a question attaching to its call's
row versus drawing its own.
Not ported: TranscriptUnits.kt's flatten of a row into bounded Compose
list units (a fact about that UI framework, not the transcript), and
joinPages/healSplitMessage/adoptRun (page-boundary healing) -- both
recorded in CLIENT_CORE.md as left for whoever picks this up next.
Also noted there: event_model::Event has no Unknown catch-all, so an
event type this build doesn't recognise fails to parse rather than
degrading to a placeholder row, unlike Events.kt's hand-kept mirror.
cargo test (85 passed), clippy --all-targets and fmt clean.

Adds sse.rs (a pure port of Sse.kt's frame parser), api.rs (a Transport
trait plus a ureq-backed implementation and an ApiClient covering the
session lifecycle: list/read, message/unqueue/answer,
interrupt/stop/start, title/cwd/model/permission-mode/notify,
command/compact, delete, and a transcript page), and event_stream.rs
(follow_session_events, mirroring EventStream.kt's reset/event split).
ureq rather than reqwest: server/ already depends on it for its own
outbound HTTPS, this stays blocking like Api.kt's HttpURLConnection
calls with no async runtime to carry, and its own PEM cert support
means no extra rustls/rustls-pemfile dependency to pin. Network I/O
sits behind Transport so ApiClient and follow_session_events are
tested with fakes, no server involved.
Not yet covered, tracked in CLIENT_CORE.md: setups, the file explorer,
usage, models, and attachments/import.
cargo test (78 passed), clippy --all-targets and fmt clean.

Ports app/.../TranscriptCache.kt (chunked JSONL directory, suffix/gap
tracking, backwards line reader, damage recovery, eviction) with the
full TranscriptCacheTest suite (18 cases). One correction the port
found in translation: SessionCache::guard's Err branch would have
disabled the whole cache on a single damaged chunk, since a damaged
suffix and a real I/O failure both arrived as Err from the same
closure -- separated so damage discards only the one session, matching
the Kotlin original's separate `catch (e: Damaged)` from
`catch (e: IOException)`.
cargo test (67 passed), clippy --all-targets and fmt clean.

Ports app/.../Ansi.kt, Highlighter.kt, Languages.kt and MarkdownSyntax.kt
to client-core, module for module, with every HighlighterTest and
AnsiTest case ported alongside (49 tests total). ansi.rs replaces
Compose's AnnotatedString/SpanStyle with a plain StyledText/Style pair
so the crate stays free of any UI framework, per RUST.md.
cargo test (49 passed), clippy --all-targets and fmt clean.
