Extensions can dynamically remove custom providers via pi.unregisterProvider(name), restoring any built-in models that were overridden, without requiring /reload (docs).
pi.registerProvider() now takes effect immediately when called outside the initial extension load phase (e.g. from a command handler), removing the need for /reload after late registrations.

pi.unregisterProvider(name) removes a dynamically registered provider and its models from the registry without requiring /reload. Built-in models that were overridden by the provider are restored (#1669 by @aliou).

pi.registerProvider() now takes effect immediately when called after the initial extension load phase (e.g. from a command handler). Previously the registration sat in a pending queue that was never flushed until the next /reload (#1669 by @aliou).
Fixed duplicate session headers when forking from a point before any assistant message. createBranchedSession now defers file creation to _persist() when the branched path has no assistant message, matching the newSession() contract (#1672 by @w-winter).
Fixed SIGINT being delivered to pi while the process is suspended (e.g. via ctrl+z), which could corrupt terminal state on resume (#1668 by @aliou).
Fixed Z.ai thinking control using wrong parameter name, causing thinking to always be enabled and wasting tokens/latency (#1674 by @okuyam2y)
Fixed redacted_thinking blocks being silently dropped during Anthropic streaming, and related issues with interleaved-thinking beta headers and temperature being sent alongside extended thinking (#1665 by @tctev)
Fixed (external, cli) user-agent flag causing 401 errors on Anthropic setup-token endpoint (#1677 by @LazerLance777)
Fixed crash when OpenAI-compatible provider returns a chunk with no choices array (#1671)
