SnapOtter 59c9df3f0d fix: add missing SVG XXE security test fixtures
The adversarial-security integration test reads two SVG fixture files
that were never committed, causing CI to fail with ENOENT.

SnapOtterandGitHub 5a32e29b8c fix(security): security audit and hardening (#207)
* fix(security): harden SVG sanitizer, rate limiting, and analytics defaults

- SVG: add control-char stripping in href values to block whitespace/null-byte
  obfuscated javascript: URIs; block <feImage> with external href (SSRF via
  SVG filter primitives); expand test suite to 32 inline bypass payloads
- Rate limiting: add per-route limits on tool endpoints (60/min) and batch
  (20/min); fix compose files defaulting RATE_LIMIT_PER_MIN to 0 which mapped
  to 50,000 in code; simplify rate limit registration to use env.ts default
- Analytics: default ANALYTICS_ENABLED to false so self-hosters do not
  unknowingly send telemetry
- Docker: add --max-time 5 and -s flags to compose healthcheck curl commands

* fix: remove stale login limit bypass, reduce error log noise, clean up fixtures

- Fix getLoginAttemptLimit() ignoring LOGIN_ATTEMPT_LIMIT when global rate
  limit exceeded 1000/min, which let the global limit override the stricter
  per-route login brute-force protection
- Downgrade rate limit 429 responses from error to warn level in the global
  error handler to avoid log noise and unnecessary Sentry reports
- Log 4xx client errors at warn level instead of error level
- Remove 11 orphaned SVG attack fixture files replaced by inline test payloads

SnapOtter 4e64ee2779 fix(security): comprehensive security audit and hardening
Auth: login rate limit 30/min (was 500), global rate limit 1000/min (was
unlimited), password/username max lengths on all Zod schemas, session
invalidation on role change, API key legacy scan bounded to 100 keys.

SVG: hardened regex sanitizer with CDATA stripping, XML entity decoding,
set/animate/iframe/embed blocking, comprehensive data: URI blocking,
use element external href blocking. 11 attack payload fixtures added.

SSRF: fixed DNS rebinding TOCTOU by pinning resolved IPs via custom
HTTP/HTTPS agents. Added 6to4 and NAT64 to blocked IPv6 ranges.

Docker: capability dropping (cap_drop ALL + minimal cap_add), resource
limits (4g/8g mem, 512/1024 pids), healthcheck timeout, password
removed from startup banner, default password warning comments.

Network: CSP and HSTS applied in all environments (not just production),
stack traces removed from all error responses, internal paths stripped
from error details, per-route rate limits on uploads (60/min) and URL
fetches (200/hour).

Files: exclusive temp file creation (O_EXCL), disk space circuit
breaker, per-user storage quotas, settings payload 64KB size guard.

Python sidecar: script name allowlist in dispatcher, minimal environment
for subprocess spawns.

Dependencies: fixed 6 production CVEs (drizzle-orm, fastify, fast-uri,
@fastify/static, next, archiver/lodash). Pinned all GitHub Actions to
SHA hashes.

114 security tests added. Full OWASP Top 10 penetration test matrix
verified against production Docker container (30/30 pass after
hardening).
