Extend session sources to OpenCode, Cursor, and DeepSeek Harness (dsh)

[miniLV]

Context

Today the memory loop compiles only Codex and Claude Code sessions into Daily Wiki pages. SCHEMA.md treats these as the supported raw session sources, and scripts/capture-ai-chats.mjs hard-codes two source scanners. Conversations with other local agents (OpenCode, Cursor, DeepSeek Harness) are not captured, so the vault misses a meaningful slice of engineering work.

Goal

Add three additional session sources so a user's conversations with OpenCode, Cursor, and DeepSeek Harness are automatically organized into the local Daily Wiki:

• OpenCode — ~/.local/share/opencode/opencode.db (SQLite: session / message / part), with a fallback to the legacy storage/ JSON tree.
• Cursor — ~/Library/Application Support/Cursor/User workspaceStorage + globalStorage state.vscdb (SQLite ItemTable / cursorDiskKV). This store is version-fragile (2.x composerData vs 3.0 bubbleId:*); treat as best-effort and degrade to a warning instead of crashing.
• DeepSeek Harness (dsh) — ~/.dsh/storages/ event-sourced JSONL session logs, based on the official deepseek-harness persistence format (best-effort, no real sessions yet to validate against).

Requirements

• New source flags: opencodeSourcesEnabled, cursorSourcesEnabled, dshSourcesEnabled — all default off; a source is only consulted when === true (keeps existing sourcesConfirmed gating intact).
• capture-ai-chats.mjs reads these flags, resolves each adapter to normalized {role, text, timestamp} records, and reuses the existing buildSessionFromRecords evidence pipeline — no duplicated normalization.
• SQLite is read with built-in node:sqlite (Node ≥22.13) so no new dependency is added. If node:sqlite is unavailable or a DB is missing/incompatible, skip that source with a warning rather than failing the whole capture.
• Evidence IDs and agent names: opencode-* / OpenCode, cursor-* / Cursor, dsh-* / DeepSeek Harness.
• Config UI: add the three source checkboxes to the source modal; update readForm/writeForm/source-gate detail and the zh/en strings.
• SCHEMA.md generalizes the agent: value list; wiki/templates/Daily AI Chat Summary Template.md and the ingest/setup skill wording are updated.
• README.md + README.en.md supported-source table updated.

Constraint

Skill sync to an agent stays Codex-only (as today) — the engineering-memory-loader continues to be exposed only to ~/.codex/skills. The new options are extraction sources only, not skill-sync targets.

Notes / Caveats

• Cursor is the fragile source: its on-disk schema moved across Cursor versions and on the author's machine the workspace composerData composer list only partially overlaps the global bubbleId:* store. Confirmed working for the global-bubble path with lastUpdatedAt-based dates; missing_model is expected (Cursor records no model). Validate on real data before relying on it.
• dsh default persistence is Zstandard-frame JSONL; the adapter reads raw-line JSONL and skips Zstd frames (no zstd binary dependency).

Verify

• node --test scripts/*.test.mjs (53 tests incl. new opencode + dsh fixtures) passes.
• node scripts/wiki-lint.mjs reports 0 errors / 0 warnings.
• Capture on the author's machine discovers OpenCode sessions for 2026-08-30 and Cursor sessions for 2025-05-06 without crashing.
