Root page loads should not automatically project a localStorage-saved running session into the active pane. Keep explicit /session/<sid> behavior unchanged while leaving the saved session discoverable from the sidebar.
(cherry picked from commit bb60cf21d911a84e285363bcecf46fb441181fb9)
PR #1358 added the client-side lineage collapse helper, but
/api/sessions often did not include _lineage_root_id for the WebUI
JSON sessions visible in the sidebar. In that case the helper has no
grouping key and multiple same-title continuation rows remain visible.
This PR:
- Reads parent_session_id and end_reason from state.db.sessions for
the WebUI sidebar's session ids
- Walks the parent chain when end_reason is 'compression' or
'cli_close', producing _lineage_root_id and _compression_segment_count
- Cycle-detects via a 'seen' set
- Preserves projected lineage metadata on imported/gateway session rows
- Allows sidebar collapse to group cross-surface continuation chains
(CLI-close → WebUI continuation) while keeping non-continuation
parent rows flat

Adds a 'storage' event listener for the hermes-webui-session localStorage key. Idle tabs auto-load the new active session and re-render the sidebar; busy tabs show a toast and do not interrupt the active turn.

When a session's compression lineage spans multiple segments (linked via _lineage_root_id from api/agent_sessions.py), the sidebar previously rendered each segment as a separate top-level row. Adds _collapseSessionLineageForSidebar() that groups by lineage root and keeps only the most recently active tip per group, with a _lineage_collapsed_count marker for future UI affordances.

Session.load_metadata_only().compact() was dropping is_cli_session, source_tag, session_source, and source_label, so imported CLI/gateway sessions lost their provenance in sidebar/API payloads. Adds these to METADATA_FIELDS and Session.compact().
