solana-streamer v1.5.2

What's Changed

• Updated the published crate to depend on crates.io sol-parser-sdk 0.5.2 instead of any local path dependency.
• Switched ShredStream delivery to the SDK direct-callback path to reduce queue scheduling latency.
• Preserved unknown ShredStream tx_index values as None instead of fabricating placeholder indexes.
• Kept PumpFunCreateToken filters backward-compatible with CreateV2 events.
• Started the ShredStream metrics task only after successful SDK subscription setup.
• Updated English and Chinese README release notes and install snippets for 1.5.2.
