Feat/temporal (#46)

* refactor: modularize claude-executor and extract shared utilities

- Extract message handling into src/ai/message-handlers.ts with pure functions
- Extract output formatting into src/ai/output-formatters.ts
- Extract progress management into src/ai/progress-manager.ts
- Add audit-logger.ts with Null Object pattern for optional logging
- Add shared utilities: formatting.ts, file-io.ts, functional.ts
- Consolidate getPromptNameForAgent into src/types/agents.ts

* feat: add Claude Code custom commands for debug and review

* feat: add Temporal integration foundation (phase 1-2)

- Add Temporal SDK dependencies (@temporalio/client, worker, workflow, activity)
- Add shared types for pipeline state, metrics, and progress queries
- Add classifyErrorForTemporal() for retry behavior classification
- Add docker-compose for Temporal server with SQLite persistence

* feat: add Temporal activities for agent execution (phase 3)

- Add activities.ts with heartbeat loop, git checkpoint/rollback, and error classification
- Export runClaudePrompt, validateAgentOutput, ClaudePromptResult for Temporal use
- Track attempt number via Temporal Context for accurate audit logging
- Rollback git workspace before retry to ensure clean state

* feat: add Temporal workflow for 5-phase pipeline orchestration (phase 4)

* feat: add Temporal worker, client, and query tools (phase 5)

- Add worker.ts with workflow bundling and graceful shutdown
- Add client.ts CLI to start pipelines with progress polling
- Add query.ts CLI to inspect running workflow state
- Fix buffer overflow by truncating error messages and stack traces
- Skip git operations gracefully on non-git repositories
- Add kill.sh/start.sh dev scripts and Dockerfile.worker

* feat: fix Docker worker container setup

- Install uv instead of deprecated uvx package
- Add mcp-server and configs directories to container
- Mount target repo dynamically via TARGET_REPO env variable

* fix: add report assembly step to Temporal workflow

- Add assembleReportActivity to concatenate exploitation evidence files before report agent runs
- Call assembleFinalReport in workflow Phase 5 before runReportAgent
- Ensure deliverables directory exists before writing final report
- Simplify pipeline-testing report prompt to just prepend header

* refactor: consolidate Docker setup to root docker-compose.yml

* feat: improve Temporal client UX and env handling

- Change default to fire-and-forget (--wait flag to opt-in)
- Add splash screen and improve console output formatting
- Add .env to gitignore, remove from dockerignore for container access
- Add Taskfile for common development commands

* refactor: simplify session ID handling and improve Taskfile options

- Include hostname in workflow ID for better audit log organization
- Extract sanitizeHostname utility to audit/utils.ts for reuse
- Remove unused generateSessionLogPath and buildLogFilePath functions
- Simplify Taskfile with CONFIG/OUTPUT/CLEAN named parameters

* chore: add .env.example and simplify .gitignore

* docs: update README and CLAUDE.md for Temporal workflow usage

- Replace Docker CLI instructions with Task-based commands
- Add monitoring/stopping sections and workflow examples
- Document Temporal orchestration layer and troubleshooting
- Simplify file structure to key files overview

* refactor: replace Taskfile with bash CLI script

- Add shannon bash script with start/logs/query/stop/help commands
- Remove Taskfile.yml dependency (no longer requires Task installation)
- Update README.md and CLAUDE.md to use ./shannon commands
- Update client.ts output to show ./shannon commands

* docs: fix deliverable filename in README

* refactor: remove direct CLI and .shannon-store.json in favor of Temporal

- Delete src/shannon.ts direct CLI entry point (Temporal is now the only mode)
- Remove .shannon-store.json session lock (Temporal handles workflow deduplication)
- Remove broken scripts/export-metrics.js (imported non-existent function)
- Update package.json to remove main, start script, and bin entry
- Clean up CLAUDE.md and debug.md to remove obsolete references

* chore: remove licensing comments from prompt files to prevent leaking into actual prompts

* fix: resolve parallel workflow race conditions and retry logic bugs

- Fix save_deliverable race condition using closure pattern instead of global variable
- Fix error classification order so OutputValidationError matches before generic validation
- Fix ApplicationFailure re-classification bug by checking instanceof before re-throwing
- Add per-error-type retry limits (3 for output validation, 50 for billing)
- Add fast retry intervals for pipeline testing mode (10s vs 5min)
- Increase worker concurrent activities to 25 for parallel workflows

* refactor: pipeline vuln→exploit workflow for parallel execution

- Replace sync barrier between vuln/exploit phases with independent pipelines
- Each vuln type runs: vuln agent → queue check → conditional exploit
- Add checkExploitationQueue activity to skip exploits when no vulns found
- Use Promise.allSettled for graceful failure handling across pipelines
- Add PipelineSummary type for aggregated cost/duration/turns metrics

* fix: re-throw retryable errors in checkExploitationQueue

* fix: detect and retry on Claude Code spending cap errors

- Add spending cap pattern detection in detectApiError() with retryable error
- Add matching patterns to classifyErrorForTemporal() for proper Temporal retry
- Add defense-in-depth safeguard in runClaudePrompt() for $0 cost / low turn detection
- Add final sanity check in activities before declaring success

* fix: increase heartbeat timeout to prevent false worker-dead detection

Original 30s timeout was from POC spec assuming <5min activities. With
hour-long activities and multiple concurrent workflows sharing one worker,
resource contention causes event loop stalls exceeding 30s, triggering
false heartbeat timeouts. Increased to 10min (prod) and 5min (testing).

* fix: temporal db init

* fix: persist home dir

* feat: add per-workflow unified logging with ./shannon logs ID=<workflow-id>

- Add WorkflowLogger class for human-readable, per-workflow log files
- Create workflow.log in audit-logs/{workflowId}/ with phase, agent, tool, and LLM events
- Update ./shannon logs to require ID param and tail specific workflow log
- Add phase transition logging at workflow boundaries
- Include workflow completion summary with agent breakdown (duration, cost)
- Mount audit-logs volume in docker-compose for host access
