Refactor platform module, add pipe module, denuvo auth,inject and localize README

[OpenSteam001]

Summary

This PR refactors the platform boundary, introduces a PipeManager for Steam IPC handling, and uses that structure to improve Denuvo authorization timing and SteamID handling. It also adds a configurable injection mechanism, which can be enabled by setting the injection options in the config file.

It also adds Spanish README localization. Thanks to @RikkoPoto (#105 )

OSTPlatform

• Introduce OSTPlatform as the low-level OS abstraction layer.
• Keep the current backend Windows-only, while making the project structure ready for future Linux platform implementations.
• Add OSTP_LOG_* platform logging and route it into the main logger in Debug builds.

Denuvo Authorization

attempts to address the README TODOs:

• Auto Denuvo authorization sharing for legitimate accounts.
• Finding a safer point to switch GetSteamID without affecting save-file binding.

related issue:

• try to fix [FEATURE] Game saves protected by Denuvo and SteamStub are prone to being lost. #76
• try to fix 什么时候可以出切号授权，这个是最重要的，是否需要赞助 #103

Injection

• Add optional injection configuration in opensteamtool.toml via [inject] enabled, library_x64, and library_x86
• library_x64 and library_x86 may be absolute paths, or relative paths resolved from the Steam root directory.
• Thanks to the idea proposed by @Ran-Mewo (Add -onlinefix support for games that use EOS matchmaking #97)

Config / Lua Hot Reload

• Add hot reload support for opensteamtool.toml.
• Fixes [BUG] OST v1.4.7 Debug: Issue with modifying the .lua binding manifest while Steam is open #102 , Make setManifestid overrides participate in Lua hot reload.

README Localization

• Add a centered language selector to README.md and add Spanish translation as README_ES.md.

Honor cbMaxTicket when returning encrypted tickets

This adds a caller-provided maximum ticket size, but HandlerPost_IClientUser_GetEncryptedAppTicket still never parses this request field and always grows pWrite by the full cached ticket size before setting pcbTicket. When a client supplies a smaller cbMaxTicket, the hook can return/write more ticket bytes than the caller requested instead of rejecting it, unlike the ownership-ticket handler which checks its max buffer before writing.

Retry injection after failed attempts

With injection enabled, ClaimInjection(ctx.process) records the process before InjectLibrary reports whether the DLL was actually loaded. If the first handshake hits a transient failure such as the target still starting, module enumeration not being ready, or the configured DLL path being temporarily unavailable, every later handshake for the same process is skipped because the process key is already in g_injected. Mark the process as injected only after InjectStatus::Ok, or remove the claim on failure so a later pipe can retry.
