Pi v0.75.5 adds Claude adaptive thinking support

Pi continues to carve out a niche for developers who want a low-abstraction, high-control alternative to heavyweight AI IDEs like Cursor.

• –Adaptive thinking support for Anthropic models allows the agent to opt into "thinking" tokens, improving performance on complex reasoning tasks through extended internal chain-of-thought.
• –The shift to asynchronous filesystem operations and background image processing on Windows significantly improves TUI responsiveness during heavy I/O and visual tasks.
• –Replacing the large koffi dependency with a tiny native helper reduces install size and cold-start time while preserving essential terminal inputs like Shift+Tab.
• –Improvements to pi update ensure git-pinned packages are reconciled correctly without losing user-defined filters, fixing a common friction point in package management.
• –The release demonstrates a commitment to the "vibe coding" philosophy by prioritizing performance and UI "un-cluttering" over feature bloat.
