fix(guards): read .gitignore like git, allowlist settings.json keys, refuse workspaces and bunfig.toml

Three findings on tools/security_guards.py and tools/install_portal_clis.py.

GHSA-rv99-7xf2-8f4p (Martin Vlach, @Huge): the gitignore guard stripped
both ends of each line, but git drops only unescaped trailing whitespace,
so " salary_data.json" satisfied the required-rule check while git had
stopped ignoring the file. Only the root file was read, though a
.gitignore in a subdirectory outranks it, so a negation there re-included
personal data with CI green. Lines are now read as git reads them, and
every .gitignore below the root (outside .git and node_modules) is checked
for negations; an intentional one is allowlisted as "<dir>/.gitignore:!p".

GHSA-cqcv-crx7-x7q7 (@folovco, @Huge): the guard checked allow, ask, deny
and hooks and ignored every other key, so env, apiKeyHelper, a statusLine
command, enableAllProjectMcpServers, permissions.defaultMode or
additionalDirectories passed CI. Any top-level key outside
ALLOWED_SETTINGS_KEYS and any permissions key outside
ALLOWED_PERMISSIONS_KEYS now fails.

GHSA-wq7j-x5jq-pjrw (@folovco, @Huge), on top of #718's --ignore-scripts
(cherry-picked, rudycelekli): the installer and check 3 now refuse a
manifest that declares workspaces (whose packages bring their own
lifecycle scripts; a workspace postinstall ran under Bun 1.3.10) or that
has a bunfig.toml beside it (which reconfigures the install). The
advisory's workspace proof of concept is now skipped before bun runs.

Twelve new tests, all failing before this change; SECURITY.md, README and
SETUP describe the new checks.

It runs `bun install` in every portal CLI under `.agents/skills/*/cli/` - discovered, not listed, so a portal you add with `/add-portal` or copy from another fork is included on a fresh clone. A CLI whose `package.json` declares an install-time lifecycle script is skipped and reported rather than run. `--dry-run` shows what it would install.
It runs `bun install` in every portal CLI under `.agents/skills/*/cli/` - discovered, not listed, so a portal you add with `/add-portal` or copy from another fork is included on a fresh clone. Every install runs with `--ignore-scripts`, and a CLI whose `package.json` declares an install-time lifecycle script, `trustedDependencies` or `workspaces`, or that has a `bunfig.toml` beside it, is skipped and reported rather than run. `--dry-run` shows what it would install.
For `linkedin-search` and `freehire-search` the install is optional: both have zero runtime dependencies and run with plain `bun`; `bun install` only pulls TypeScript dev types.
