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.

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/.../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.
