* test: reproduce issue #864
Assert Cursor error paths emit agent error payloads and web UI renders
them as warning-styled events instead of neutral session messages.

* fix(cursor): surface agent errors with warning styling in web UI (closes#864)
Route Cursor stderr, init, prompt, and legacy exit failures through
sendAgentMessage({ type: 'error' }) and teach the web chat layer to
render error events with a warning icon instead of neutral info text.

* refactor(web): extract normalizeTimestamp helper in presentation
Extract the shared seconds-vs-milliseconds normalization logic into
a private `normalizeTimestamp()` helper. No behavior change —
`formatUnixTimestamp()` produces identical output.
* refactor(web): return AgentEvent from parseClaudeUsageLimit
Change return type from `number | null` to `AgentEvent | null` so
the caller doesn't need to construct the event object. No behavior
change — the same `limit-reached` event is produced.
* feat(cli): convert rate_limit_event to standardized text format
Parse undocumented Claude `rate_limit_event` JSON in the CLI adapter
layer (AcpMessageHandler) before it reaches the web.
Converted text format (pipe-delimited):
- "Claude AI usage limit warning|{ts}|{pct}|{rateLimitType}"
- "Claude AI usage limit reached|{ts}|{rateLimitType}"
Status handling:
- `allowed_warning` → warning text with utilization and limit type
- `rejected` → reached text with limit type
- `allowed` → silently suppressed (noise)
- unknown statuses → passed through as-is (forward-compatible)
* feat(web): display rate limit warnings with limit type
Parse standardized pipe-delimited text from the CLI adapter into
`limit-warning` and `limit-reached` events, displaying the rate
limit type (5-hour, 7-day) when available.
- `limit-warning`: "⚠️ Usage limit 90% (5-hour) · resets 2:00 PM"
- `limit-reached`: "⏳ Usage limit reached (5-hour) until 4/2/2026"
- Backward compatible: `limit-reached` without limitType still works
The `reached` regex uses `(?:\|([^|]*))?$` to optionally match the
limitType field, maintaining compatibility with the existing format.
* refactor(cli): move rate limit parsing out of flushText
Remove rate limit detection from flushText() back to plain buffer
flush. The next commit will re-add parsing at the chunk level
(handleUpdate) where it can intercept before buffer merging.
Includes failing tests that demonstrate the mixed-chunk bug:
when a rate_limit_event chunk arrives in the same turn as normal
text, the JSON leaks into the merged buffer.
* fix(cli): intercept rate_limit_event at chunk level, not flush
Move rate limit detection from flushText() to the agentMessageChunk
handler so it fires before the chunk enters the shared text buffer.
Previously, a rate_limit_event chunk arriving in the same turn as
normal text would merge into bufferedText and leak as raw JSON.
Now the chunk is intercepted individually, the existing buffer is
flushed first (preserving prior text), and the converted message
is emitted separately.
* fix(cli): skip flush when suppressing allowed rate_limit_event
Only flush the text buffer when the parsed event will actually be
displayed. Suppressed events (e.g. status: 'allowed') now return
immediately without flushing, preventing a text → allowed → text
sequence from splitting one answer into two agent-text blocks.
* fix(web): include limitType in limit-reached reconcile key
Without this, reprocessing a message from the old format (no
limitType) to the new typed format reuses the stale block and
the (5-hour)/(7-day) suffix never appears.
Adds support for Claude Code's microcompact_boundary system message type to display context microcompaction events with token savings information in the chat UI. Shows a package icon with formatted token count (e.g., "Context compacted (saved 32K tokens)"). close#108
Introduces support for displaying API error system messages in the web UI with
automatic folding of consecutive retry messages to show only the latest state.
