Keysat d0e98424c1 Fix five P0/P1 security & correctness findings from the full-eval
- Arbitrary file write (P0): validate import keys in /api/library/import via
  a now-exported safeFilename(); a ../../ key is skipped, not written out of
  the scope dir.
- SSRF (P0): guard downloadPodcastAudio — reject non-HTTP(S) schemes, block
  IP-literal and DNS-resolved private/link-local/loopback/reserved/multicast
  and embedded-IPv4 IPv6 targets (closes DNS rebinding), cap + resolve redirects.
- ESM require (P1): top-level import of randomBytes in license-purchase.js
  (the inner require threw on the anon purchase-settle path).
- Concurrency lock (P1): skip the process-global free-tier slot in multi-mode
  so it no longer serializes every cloud tenant onto one job.
- X-Forwarded-For bypass (P1): set Express trust proxy from
  RECAP_TRUSTED_PROXY_HOPS (default 1); getClientIp now reads req.ip instead
  of a client-spoofable XFF entry.

Tests added for safeFilename, the SSRF guard, and getClientIp (119 pass).
Registry blockers deferred (ROADMAP); leaked-key history purge queued.

Keysat 0ae59f3550 Add multi-tenant cloud mode: self-serve purchase, credit metering, core-decoupling
Introduces RECAP_MODE=multi alongside single-mode self-host:
- Tenant auth + accounts (magic-link via System SMTP), per-tenant credit pool,
  anonymous trial minting with per-IP/-64 caps
- Self-serve Pro/Max purchase: inline Lightning (BTCPay) + card (Zaprite),
  prepaid 30-day periods, expiry-reminder emails
- Core-decoupling: relay owns cloud tier/expiry keyed by Recaps user-id
- SQLite (better-sqlite3) schema for multi-mode; filesystem unchanged for single
- StartOS actions/versions through 0.2.155
