feat: allow proxy bypassing with 'NONE' string

[AlejandroAkbal]

• Added 'NONE' as a valid magic string value for baseUrl in BooruOutboundProxyPolicy.
• Updated validateOutboundProxyPolicy to intercept 'NONE' and avoid triggering normal URL validation checks.
• Modified the monkey-patched method interceptors inside applyOutboundProxy to check for proxyPolicy.baseUrl === 'NONE' and return the upstream URL natively without wrapping it in a proxy.
• Added comprehensive unit testing to booru.service.spec.ts to assert that proxy generation handles both bypass and rotating states seamlessly.

📝 Walkthrough

Walkthrough

Outbound proxy policies now accept baseUrl: "NONE" to bypass proxying for selected providers. URL construction preserves upstream query and authentication parameters, while rotation tests cover direct requests and continued proxy rotation.

Changes

Outbound Proxy Bypass

Layer / File(s)	Summary
NONE policy validation src/booru/booru.service.ts	Outbound proxy policies accept the NONE sentinel and normalize it with targetParam set to q, without URL or HTTPS validation.
Direct URL application and rotation coverage src/booru/booru.service.ts, src/booru/booru.service.spec.ts	URL construction returns the upstream URL unchanged for NONE; tests cover preserved query/auth parameters, direct URLs during rotation, and rotation behavior for non-fetching APIs.
