fix(#1423): Prevent command injection in Electron MemPalace bridge

SECURITY: The Electron IPC handler exposed raw child_process.exec() to
renderer code, allowing arbitrary command execution via shell metacharacters.

Changes:
- electron-main.js: Replace exec() with execFile() + argument arrays
  Add operation whitelist (ALLOWED_MEMPALACE_OPS)
  Add sanitizeArg() to reject shell metacharacters (;, &, |, `, $, etc.)
  Both exec-python (legacy) and new mempalace-exec IPC handlers are safe
- mempalace.js: Replace template-interpolated shell strings with safe
  _exec(op, ...args) method using the new mempalace-exec IPC
- app.js: Remove direct execPython call with template interpolation,
  use mempalace.addDrawer() instead
- preload.js: New context bridge exposing mempalaceExec and restricted
  execPython to renderer
- tests/test_electron_security.py: 7 security assertions

The old pattern:
  exec(`mempalace search "${userInput}"`)
  // user submits: "; rm -rf /"
  // executes: mempalace search ""; rm -rf /""

The new pattern:
  execFile('mempalace', ['search', userInput])
  // user submits: "; rm -rf /"
  // executes: mempalace 'search' '"; rm -rf /"'
  // metacharacters are rejected by sanitizeArg()

-## Expected Outcomes by 7 AM
-
-### API Calls
-- Total calls: ~2,010
-- Successful completions: ~1,400 (70%)

-- 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 |

-
-### 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)
