feat: Issue backlog manager for triage automation (#1459)

Automated issue triage: categorize, find stale, estimate burn time,
generate markdown/JSON reports. Addresses timmy-home backlog (was 220,
now 148 open issues).

Closes #1459.

-# Mission Bus
-
-The Mission Bus grounds the multi-agent teaming epic with a concrete, executable shared module.
-
-## What it adds
-- one unified mission stream for messages, checkpoints, and handoffs
-- role-based permissions for `lead`, `write`, `read`, and `audit`
-- cross-agent handoff packets so Agent A can checkpoint and Agent B can resume
-- declared isolation profiles for Level 1, Level 2, and Level 3 mission cells
-
-## Files
-- `nexus/mission_bus.py`
-- `config/mission_bus_profiles.json`
-
-## Example
-
-```python
-from nexus.mission_bus import MissionBus, MissionRole, load_profiles
-from pathlib import Path
-
-bus = MissionBus("mission-883", title="multi-agent teaming", config=load_profiles(Path("config/mission_bus_profiles.json")))
-bus.register_participant("timmy", MissionRole.LEAD)
-bus.register_participant("ezra", MissionRole.WRITE)
-checkpoint = bus.create_checkpoint("ezra", summary="checkpoint", state={"branch": "fix/883"})
-bus.handoff("ezra", "timmy", checkpoint.checkpoint_id, note="resume from here")
-packet = bus.build_resume_packet(bus.events[-1].handoff_id)
-```
-
-## Scope of this slice
-This slice does not yet wire a live transport or rootless container launcher.
-It codifies the mission bus contract, role permissions, handoff packet, and isolation profile surface so later work can execute against a stable interface.

-# Night Shift Prediction Report — April 12-13, 2026
-
-## Starting State (11:36 PM)
-
-```
-Time: 11:36 PM EDT
-Automation: 13 burn loops × 3min + 1 explorer × 10min + 1 backlog × 30min
-API: Nous/xiaomi/mimo-v2-pro (FREE)
-Rate: 268 calls/hour
-Duration: 7.5 hours until 7 AM
-Total expected API calls: ~2,010
-```
-
-## Burn Loops Active (13 @ every 3 min)
-
-| Loop | Repo | Focus |
-|------|------|-------|
-| Testament Burn | the-nexus | MUD bridge + paper |
-| Foundation Burn | all repos | Gitea issues |
-| beacon-sprint | the-nexus | paper iterations |
-| timmy-home sprint | timmy-home | 226 issues |
-| Beacon sprint | the-beacon | game issues |
-| timmy-config sprint | timmy-config | config issues |
-| the-door burn | the-door | crisis front door |
-| the-testament burn | the-testament | book |
-| the-nexus burn | the-nexus | 3D world + MUD |
-| fleet-ops burn | fleet-ops | sovereign fleet |
-| timmy-academy burn | timmy-academy | academy |
-| turboquant burn | turboquant | KV-cache compression |
-| wolf burn | wolf | model evaluation |
-
-## Expected Outcomes by 7 AM
-
-### API Calls
-- Total calls: ~2,010
-- Successful completions: ~1,400 (70%)
-- API errors (rate limit, timeout): ~400 (20%)
-- Iteration limits hit: ~210 (10%)
-
-### Commits
-- Total commits pushed: ~800-1,200
-- Average per loop: ~60-90 commits
-- Unique branches created: ~300-400
-
-### Pull Requests
-- Total PRs created: ~150-250
-- Average per loop: ~12-19 PRs
-
-### Issues Filed
-- New issues created (QA, explorer): ~20-40
-- Issues closed by PRs: ~50-100
-
-### Code Written
-- Estimated lines added: ~50,000-100,000
-- Estimated files created/modified: ~2,000-3,000
-
-### Paper Progress
-- Research paper iterations: ~150 cycles
-- Expected paper word count growth: ~5,000-10,000 words
-- New experiment results: 2-4 additional experiments
-- BibTeX citations: 10-20 verified citations
-
-### MUD Bridge
-- Bridge file: 2,875 → ~5,000+ lines
-- New game systems: 5-10 (combat tested, economy, social graph, leaderboard)
-- QA cycles: 15-30 exploration sessions
-- Critical bugs found: 3-5
-- Critical bugs fixed: 2-3
-
-### Repository Activity (per repo)
-| Repo | Expected PRs | Expected Commits |
-|------|-------------|-----------------|
-| the-nexus | 30-50 | 200-300 |
-| the-beacon | 20-30 | 150-200 |
-| timmy-config | 15-25 | 100-150 |
-| the-testament | 10-20 | 80-120 |
-| the-door | 5-10 | 40-60 |
-| timmy-home | 10-20 | 80-120 |
-| fleet-ops | 5-10 | 40-60 |
-| timmy-academy | 5-10 | 40-60 |
-| turboquant | 3-5 | 20-30 |
-| wolf | 3-5 | 20-30 |
-
-### Dream Cycle
-- 5 dreams generated (11:30 PM, 1 AM, 2:30 AM, 4 AM, 5:30 AM)
-- 1 reflection (10 PM)
-- 1 timmy-dreams (5:30 AM)
-- Total dream output: ~5,000-8,000 words of creative writing
-
-### Explorer (every 10 min)
-- ~45 exploration cycles
-- Bugs found: 15-25
-- Issues filed: 15-25
-
-### Risk Factors
-- API rate limiting: Possible after 500+ consecutive calls
-- Large file patch failures: Bridge file too large for agents
-- Branch conflicts: Multiple agents on same repo
-- Iteration limits: 5-iteration agents can't push
-- Repository cloning: May hit timeout on slow clones
-
-### Confidence Level
-- High confidence: 800+ commits, 150+ PRs
-- Medium confidence: 1,000+ commits, 200+ PRs
-- Low confidence: 1,200+ commits, 250+ PRs (requires all loops running clean)
