# T-677: Fix fw init hook merge — pre-existing settings.json blocks framework hooks

## Context

Discovered during e2e test with vnx-orchestration (https://github.com/Vinix24/vnx-orchestration). `lib/init.sh:534` skips writing settings.json if the file already exists. Projects with pre-existing Claude Code hooks get zero framework governance hooks.

**Root cause:** `if [ ! -f "$dir/.claude/settings.json" ]` — init only writes hooks to NEW projects. Existing projects keep their original hooks untouched.

**Fix needed:** Back up existing settings.json, then overwrite with framework hooks. The framework's governance is authoritative for governed projects.

## Acceptance Criteria

### Agent
- [x] `fw init` replaces hooks in pre-existing settings.json with framework hooks
- [x] Backup of original settings.json created before replace (.pre-fw)
- [x] Test: vnx-orchestration with 8 pre-existing hooks → framework hooks applied, backup preserved

## Verification

# init.sh has merge logic (not just skip-if-exists)
grep -q "merge" lib/init.sh || grep -q "existing.*hook" lib/init.sh
