Refs #73

Scope

Adds malformed JSONL and format-drift smoke coverage for the experimental Claude Code and Pi source adapters. This is an independent test-only slice for the source-adapter hardening work.

Implementation summary

• Added a Claude Code fixture in src/sources/claude-code.test.ts that mixes malformed JSON, unsupported record types, accepted user/assistant messages, and attachment-like content.
• Added a Pi fixture in src/sources/pi.test.ts that mixes malformed JSON, unsupported future events, accepted messages, unsupported tool-call content, and a compaction summary.
• Asserted unsupported or malformed text does not leak into findSessions or getMessagePage, while accepted transcript/session evidence remains searchable.

Verification

• npx vitest run src/sources/claude-code.test.ts src/sources/pi.test.ts -> passed, 2 files / 20 tests.
• npm run check -> passed, TypeScript plus 30 files / 205 tests.
• git diff --check -- src/sources/claude-code.test.ts src/sources/pi.test.ts -> passed.

Risk

Low. This PR changes tests only; it does not change parser, source adapter, database, or CLI behavior.

Summary by cubic

Add format-drift smoke tests for claude-code and pi source adapters to ensure malformed/unsupported records are skipped and never indexed or shown. This supports Issue #73 by confirming accepted messages stay searchable and sessions render correctly.

• New Features
  • claude-code: tests mixing malformed JSON, unsupported system records, valid user/assistant messages; verifies no leakage from attachments or bad lines.
  • pi: tests mixing malformed JSON, unsupported future events/tool calls, valid messages, and a compaction summary; verifies only accepted content is searchable.
