* fix(web): filter system-injected XML tags from rendering as raw text

Claude Code injects internal messages (<task-notification>, <system-reminder>,
<command-name>, <local-command-caveat>) as user-role messages. The web UI was
rendering these as raw XML text visible to users.

- Parse <task-notification> and display as agent-event with summary text
- Silently drop <system-reminder>, <command-name>, <local-command-caveat>
- Add tests covering all injection prefixes and edge cases

* fix(web): scope system injection filtering to Claude sessions only

Address review feedback: the XML tag filtering was applied at the
generic timeline layer, which could incorrectly hide legitimate user
messages in Codex/Gemini sessions.

- Add isClaudeSession flag threaded from Session.metadata.claudeSessionId
- Only filter system-injected tags when isClaudeSession is true
- Add tests verifying non-Claude sessions pass through all messages

* fix(web): treat all string user output as sidechain to prevent prompt leaks

Restores the fix from 3cf96ab that was accidentally reverted in 2205e04.

In normalizeUserOutput(), string-content user messages arriving through
the agent output path are never real user input (real user text goes
through normalizeUserRecord). Previously, non-sidechain string messages
were emitted as role:'user', causing subagent prompts and system-injected
messages to render as user text in the web UI.

Now all string-content user messages in this path are:
- <task-notification> with summary → converted to role:'event'
- Everything else → marked as sidechain (matched to parent Task tool
  call by the tracer, or harmlessly skipped by the reducer)

This provides a root-level fix that prevents ANY string user message
from the agent output path from leaking as visible user text.

* ci: retrigger CI

* fix(web): remove superseded return-null filter from upstream PR #372

The upstream `return null` filter for <task-notification> and
<system-reminder> (from PR #372) is now superseded by the comprehensive
sidechain upgrade logic. Remove it to avoid short-circuiting the new
task-notification → event conversion.

* refactor(web): remove reducer-side system injection filtering

System-injected messages are now fully handled in normalizeUserOutput()
(normalize layer), so the redundant filtering in reduceTimeline() is no
longer needed. Removing it also eliminates the risk of accidentally
hiding legitimate user messages that happen to start with XML tags.

- Remove SYSTEM_INJECTION_PREFIXES, isSystemInjectedMessage,
  parseTaskNotificationSummary from reducerTimeline.ts
- Remove isClaudeSession plumbing from reducer.ts and SessionChat.tsx
- Simplify reducerTimeline.test.ts to only test pass-through behavior
