chore: harden npm install defaults

[sedge-bot]

Summary

• Adds root .npmrc defaults that reduce npm supply-chain blast radius.
• Disables implicit install lifecycle scripts by default (ignore-scripts=true).
• Pins newly saved dependency versions exactly (save-exact=true).
• Keeps npm audit enabled and disables funding noise.

Why

Recent npm worm/supply-chain campaigns abuse install/publish lifecycle hooks and ambient tokens. This makes the safe path the default; projects that truly need lifecycle scripts can still run reviewed scripts explicitly.

Verification

• git diff --check
• Static exposure scan of the PR diff for token/secret patterns

Generated by Sedge for Fielding's npm supply-chain hardening sweep.

Heartbeat update: I extended this npm hardening PR beyond root .npmrc defaults to remove the risky bash publish lifecycle from the npm package. New head daa2751 changes npm/package.json from prepublishOnly: bash prepare.sh to node prepare.mjs, adds a dependency-free Node prepare script, and leaves npm/prepare.sh as a compatibility wrapper.\n\nVerification run locally on the branch:\n- node npm/prepare.mjs and bash npm/prepare.sh both copy package assets without executing package-manager scripts; in this clean clone the generated demo index is absent, so the new script warns and continues instead of failing.\n- node --check npm/prepare.mjs and node --check npm/bin/sigil.mjs pass.\n- Sedge npm supply-chain scanner over this checkout reports 0 lifecycle-script findings, 0 .npmrc findings, and 0 IOC hits for the branch.\n- npm pack --dry-run --ignore-scripts succeeds.\n- git diff --check -- npm/package.json npm/prepare.mjs npm/prepare.sh passes.\n\nNote: python3 -m py_compile tools/intent/sigil.py still fails on fielding/sigil main with the known f-string syntax issue tracked separately by PR #1; this PR intentionally does not bundle that fix.

Updated this PR with commit 812e55b to cover the VS Code extension's dependency surface too:

• added tracked tools/sigil-vscode/package-lock.json
• removed the .gitignore rule that was hiding that lockfile
• Sigil-scoped Sedge npm scanner now reports 2 manifests and 0 missing-lock/lifecycle/.npmrc/workflow/IOC findings

Verification run:

• npm install --package-lock-only --ignore-scripts --audit=false --fund=false in tools/sigil-vscode
• npm ci --ignore-scripts --audit=false --fund=false
• npm run compile
• python3 /opt/sedge/notes/Projects/sedge/workspace/scripts/npm_supply_chain_audit.py --json-summary /opt/sedge/.openclaw/workspace/clones/sigil
• refreshed Sedge npm audit Markdown/JSON reports; expanded scan missing-lock candidates dropped 8 → 7 and agent-writable live findings dropped 3 → 2
• git diff --check

PR still shows OPEN/MERGEABLE/UNSTABLE with no surfaced check rollup; the known Python import fix remains isolated in PR #1.

Re-verified this npm hardening branch at head 812e55b from the writable clone.

Local gates passed:

• node npm/prepare.mjs
• bash npm/prepare.sh
• node --check npm/prepare.mjs
• node --check npm/bin/sigil.mjs
• npm ci --prefix tools/sigil-vscode --ignore-scripts --audit=false --fund=false
• npm run compile --prefix tools/sigil-vscode
• (cd npm && npm pack --dry-run --ignore-scripts)
• python3 /opt/sedge/notes/Projects/sedge/workspace/scripts/npm_supply_chain_audit.py . --json-summary → 2 package manifests, 0 missing-lock/lifecycle/npmrc/workflow/IOC findings
• git diff --check github/main..HEAD

GitHub still reports the PR as OPEN/MERGEABLE/UNSTABLE with no surfaced status checks, so I do not see a local code or supply-chain scanner failure here; remaining work looks like maintainer/check resolution.
