Refactor engine log parsing to canonical Copilot event format

[Copilot]

This change makes the Copilot event log schema the canonical parser output across engine parsers and aligns rendering on that schema. Copilot session events.jsonl inputs now pass through without conversion, while legacy Claude/Codex/Gemini/Pi/Antigravity shapes are normalized to Copilot events.

• Canonical event schema adoption

  • Added shared helpers to detect Copilot event logs and convert between legacy trace entries and Copilot event entries.
  • Standardized parser outputs on event types like session.init, assistant.message, tool.execution_start, tool.execution_complete, and session.result.

• Renderer compatibility via normalization

  • Updated shared formatter/render paths to normalize event logs into renderer-friendly structures internally.
  • Preserved existing summary/markdown output behavior while changing upstream parser output contracts.

• Parser refactors by engine

  • Updated Claude, Codex, Gemini, Pi, and Antigravity parsers to emit canonical Copilot event entries.
  • Updated Copilot parser to retain event-format inputs as-is and only synthesize missing session.result metadata when absent.

• Bootstrap/model metadata alignment

  • Updated bootstrap summary model extraction to support both legacy init entries and canonical session.init entries.

• Test updates

  • Updated parser tests to assert event-format logEntries and event-based metadata access patterns.

const canonicalLogEntries = isEventFormat
  ? logEntries
  : convertLegacyLogEntriesToCopilotEvents(logEntries, { sourceEngine: "claude" });

const conversationResult = generateConversationMarkdown(canonicalLogEntries, {
  formatToolCallback: (toolUse, toolResult) => formatToolUse(toolUse, toolResult, { includeDetailedParameters: false }),
  formatInitCallback: initEntry => formatInitializationSummary(initEntry, { includeSlashCommands: true }),
});

Pull request overview

This pull request standardizes engine log parser outputs on a canonical Copilot “event” schema, and updates shared rendering/summary code paths to accept those canonical entries (normalizing internally as needed). It also adjusts the compiled Copilot smoke workflow to use $HOME-based Copilot config paths.

Changes:

• Introduces shared helpers to detect Copilot event logs and convert between legacy trace entries and canonical Copilot event entries.
• Refactors multiple engine parsers/tests to emit and assert against canonical event entries (e.g., session.init, assistant.message, tool.execution_*, session.result).
• Updates the compiled Copilot smoke workflow to avoid hardcoded /home/runner paths and to set Copilot config env paths via $HOME.

❌ Test Quality Sentinel failed to deliver outputs during test quality analysis.

✅ Design Decision Gate 🏗️ completed the design decision gate check.

No ADR enforcement needed: PR #38781 does not have the implementation label (has_implementation_label=false) and has only 8 new lines of code in business logic directories, below the 100-line threshold (requires_adr_by_default_volume=false).

✅ Test Quality Sentinel: 73/100. Test quality is acceptable — 15.8% of modified tests are implementation tests (threshold: 30%). The 3 flagged tests are false positives where only the test accessor was refactored; all behavioral assertions remain intact. No coding-guideline violations detected.

Done. Removed the unused initEntry variable from parse_copilot_log.cjs and also fixed a pre-existing perfsprint lint error in pkg/workflow/action_resolver.go (needed for make agent-report-progress to pass). Commit: Remove unused initEntry variable; fix perfsprint lint in action_resolver.go.
