* feat: add full-text search across conversations in sidebar
Add a search mode toggle (Projects/Conversations) to the sidebar search bar.
In Conversations mode, search text content across all JSONL session files
with debounced API calls, highlighted snippets, and click-to-navigate results.
* fix: address PR review feedback - session summary tracking, search sequence invalidation, fallback navigation, SSE streaming
- Track session summaries per-session in a Map instead of file-scoped variable
- Increment searchSeqRef when clearing conversation search to invalidate in-flight requests
- Add fallback session navigation when session not loaded in sidebar paging
- Stream search results via SSE for progressive display with progress indicator
* feat(search): add Codex/Gemini search and scroll-to-message navigation
- Search now includes Codex sessions (JSONL from ~/.codex/sessions/) and
Gemini sessions (in-memory via sessionManager) in addition to Claude
- Search results include provider info and display a provider badge
- Click handler resolves the correct provider instead of hardcoding claude
- Clicking a search result loads all messages and scrolls to the matched
message with a highlight flash animation
* fix(search): Codex search path matching and scroll reliability
- Fix Codex search scanning all sessions for every project by checking
session_meta cwd match BEFORE scanning messages (was inflating match
count and hitting limit before reaching later projects)
- Fix Codex search missing user messages in response_item entries
(role=user with input_text content parts)
- Fix scroll-to-message being overridden by initial scrollToBottom
using searchScrollActiveRef to inhibit competing scroll effects
- Fix snippet matching using contiguous substring instead of
filtered words (which created non-existent phrases)
* feat(search): add Gemini CLI session support for search and history viewing
Gemini CLI sessions stored in ~/.gemini/tmp/<project>/chats/*.json are now
indexed for conversation search and can be loaded for viewing. Previously
only sessions created through the UI (sessionManager) were searchable.
* fix(search): full-word matching and longer highlight flash
- Search now uses word boundaries (\b) instead of substring matching,
so "hi" no longer matches "this"
- Highlight flash extended to 4s with thicker outline and subtle
background tint for better visibility
