feat(providers): add opt-in Claude Desktop and Pi AI session parsers #36

狀態更新（2026-10-28）

• Draft PR feat(providers): opt-in Claude Desktop and Pi AI session sources (#36) #39 已建立正式 Development 關聯，CI Build/Test 有通過紀錄；解析器均為 explicit opt-in。
• 尚待真實 Claude Desktop／Pi Session、multi-home／dedupe／pricing，以及 UI source filter/badge 的手動驗收。
• 保持 Open 至 PR 完成驗收後合併；Parent epic: selectively port b08x session intelligence, long-context retrieval, RAG chat and source adapters #31。

Parent: #31 · Phase D (P2, independent)

Scope

• Port/adapt cli/src/providers/{claude-desktop,pi}.ts from b08x. Register alongside Firstsun's existing Kilo, Claude Code, Codex, OpenCode, Gemini, Hermes, etc., without dropping any providers.
• Claude Desktop local-agent sessions: platform-correct paths and nested <account>/<project>/<session>/audit.jsonl metadata discovery, title/project path overrides, reliable format checks and deduplication with Claude Code.
• Pi AI: ~/.pi/agent/sessions discovery; JSONL event parsing with user/assistant/tool messages, compactions, usage/pricing, timestamps and safe project-path normalization.
• Integrate into multi-home source discovery, optional --source filters, Settings, tool/source badges, analytics and incremental sync (where applicable).
• Do not read secrets or start any agents; respect source exclusions, missing directories, permissions and malformed JSONL.

Acceptance

• Fixtures for each provider including malformed entries, missing metadata, tool calls, compaction, different OS paths and repeat sync; no duplicate sessions.
• Pricing and message totals correct, Firstsun's multi-home/Kilo behavior preserved.
• Each provider may be enabled/tested independently; no automatic historical import beyond user-configured source scanning.
