feat: context re-injection with periodic and keyword triggers

[kandotrun]

Problem

Previously, supermemory context was only injected on the first message of a session. Topic changes mid-session lost relevant memory context.

Changes

Periodic re-injection

New config option reinjectEveryN (default: 0 = first only). Set to e.g. 10 to re-inject context every 10 messages.

Recall keyword triggers

New keyword patterns that trigger immediate context re-injection:

English: recall, what do you remember, check memory, search memory
Japanese: 思い出して, 記憶を検索, メモリ確認, 何か覚えてる

Configurable via recallKeywordPatterns in supermemory.jsonc.

Implementation

• Replace boolean injectedSessions Set with per-session message counter
• Inject context when: first message OR recall keyword OR periodic interval
• Clean up session state on session.deleted

Config example

// ~/.config/opencode/supermemory.jsonc
{
  "reinjectEveryN": 10,
  "recallKeywordPatterns": ["my custom pattern"]
}

Dependencies

• Depends on fix: use prt_ prefix for all part IDs (OpenCode v1.2.25+ compat) #1 (Part ID fix)
• Depends on feat: add Japanese keyword patterns and session-end auto-save #2 (Japanese keywords + session save)
