fix(sdk): re-arm triggered skills after condensation

AGENT:
This PR was prepared by an AI agent (OpenAI Codex) on behalf of uuzzrm. The implementation and verification details are included below.

Why

Triggered knowledge skills and path-scoped rules are currently deduplicated for the entire conversation. If condensation forgets the event that carried the trigger content, the deduplication marker remains in ConversationState, so later matching triggers are silently skipped.

Summary

• Rebuild keyword-skill and path-rule activation state from the active conversation view after a Condensation event is applied.
• Preserve the existing once-per-active-view behavior when the activation event remains available.
• Add session-level regression coverage for keyword skills and path rules through LocalConversation.condense().

Issue Number

Fixes #4544

How to Test

The regression tests exercise the real LocalConversation.condense() path with an LLMSummarizingCondenser, persisted events, active-view condensation, and a subsequent matching trigger.

make build
uv run pre-commit run --files openhands-sdk/openhands/sdk/conversation/impl/local_conversation.py tests/sdk/conversation/test_triggered_skills_after_condensation.py
uv run pytest tests/sdk/conversation/test_path_rules_injection.py tests/sdk/conversation/local/test_conversation_send_message.py tests/sdk/conversation/test_condense.py tests/sdk/conversation/test_triggered_skills_after_condensation.py -q

The focused command completed with 52 passed tests. tests/sdk/conversation/goal/test_render_transcript.py also passed independently. A full tests/sdk/conversation run was attempted, but the local test run exhausted temporary-disk space before it could produce a final directory-wide result; no full-suite pass is claimed.
