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()

-# Resurrection Pool
-
-The Resurrection Pool is a mission-aware layer on top of the existing Lazarus registry.
-
-It adds three concrete behaviors:
-- configurable dead-agent detection timeout
-- yes/no/ask revival policy resolution per mission or agent
-- approval packet generation for Telegram / Nostr when human sign-off is required
-
-## Files
-- `scripts/resurrection_pool.py`
-- `config/resurrection_pool.json`
-
-## Example usage
-
-```bash
-python scripts/resurrection_pool.py --json --dry-run
-python scripts/resurrection_pool.py --execute
-```
-
-## Policy model
-- `yes` → local agents auto-restart; remote agents prefer a healthy substitute
-- `ask` → generate an approval request packet with Telegram / Nostr targets
-- `no` → suppress automatic revival
-
-## Notes
-This grounds issue #882 in executable code, but it does not yet wire live Telegram or Nostr delivery. The current slice produces the approval packet and restart/substitution plan the surrounding ops loop can act on.

-
-### 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)
