fix(chat): sync live-stream fence strip regex with backend TOOL_TAGS

The browser-side EXEC_FENCE_RE only covered 6 tool names
(web_search, read_file, write_file, create_document,
edit_document, update_document) while the backend strips all
TOOL_TAGS from persisted round_texts. This caused executed
fenced tool calls (e.g. list_emails, send_email) to remain
visible in the live streaming view until session reload.

Replace the hardcoded regex with an EXEC_TOOL_TAGS array
sourced from the same set as src/agent_tools/__init__.py
(minus bash/python/ls which are valid code-block identifiers),
and build EXEC_FENCE_RE from it.

Fixes #3993
