DeepSeek thinking mode may return empty reasoning_content on assistant
messages in a tool call chain, which must be sent back in subsequent
requests. The interleaved transform's truthy check was dropping it.

Always set providerOptions.openaiCompatible[field] for assistant
messages so the AI SDK's metadata spread carries it through.

…g and streaming paths

Three truthy checks were dropping empty reasoning_content ('') from DeepSeek
V4's thinking mode responses, causing 'must be passed back to the API' errors
in multi-turn tool call chains:

1. Non-streaming parser: if (reasoning != null && reasoning.length > 0)
   -> Now: if (reasoning != null) to preserve empty strings
2. Streaming parser: if (reasoningContent) truthy check
   -> Now: if ('reasoning_text' in delta) to detect field presence
3. Outbound converter: if (part.text) reasoningText = part.text
   -> Now: reasoningText = part.text ?? '' to preserve empty text

PR anomalyco#24146 fixed the transform.ts path; this completes the remaining cases.

…ti-turn conversations

Fixes the two-layer bug where reasoning_content is dropped on conversation
replay for DeepSeek thinking mode and OpenRouter-routed DeepSeek models.

Three changes:

1. provider.ts: Auto-enable interleaved for reasoning models
   - When model.reasoning is true but interleaved is not explicitly set,
     default to { field: "reasoning_content" } instead of false
   - This triggers the interleaved transform that extracts reasoning
     and passes it via providerOptions

2. transform.ts: Use dynamic SDK key in interleaved transform
   - Replace hardcoded "openaiCompatible" with sdkKey(model.api.npm)
   - Fixes OpenRouter provider which expects "openrouter" key, not
     "openaiCompatible" (prevents key mismatch in providerOptions)

3. transform.ts: Inject reasoning_content for ALL assistant messages
   - New fallback transform fires when capabilities.reasoning is true
   - Sets reasoning_content: "" in providerOptions for every assistant
     message, including historical messages stored before reasoning mode
     was enabled (no reasoning part to extract from)
   - Also expands DeepSeek detection to check model.id in addition to
     model.api.id, covering OpenRouter-routed DeepSeek models

The permission configuration previously used a generic record type that didn't offer editor completions. Updated the schema to explicitly list all tool permission keys (read, edit, glob, grep, list, bash, task, external_directory, lsp, skill, todowrite, question, webfetch, websearch, codesearch, doom_loop) with proper types, enabling autocomplete when editing permission files.

Moves effect logging, observability, runtime utilities, flags, installation

single source of truth for foundational utilities.

All internal imports updated to use @opencode-ai/core paths for consistency.

Move the Global module from packages/opencode/src/global to packages/core/src/global
to provide a unified location for managing XDG directories and application paths.
This eliminates duplicate path definitions across packages and ensures consistent
access to data, config, cache, state, log, and bin directories throughout the codebase.

* core: move cross-spawn-spawner from opencode to core package

Moved the cross-spawn-spawner module from packages/opencode to packages/core
to enable code sharing across the monorepo. This consolidates the process
spawning infrastructure into the core package so other packages can use
cross-platform child process spawning without duplicating the implementation.

Updated all import statements across the codebase to reference the new
location (@opencode-ai/core/effect/cross-spawn-spawner). Removed the
local copy from the opencode package along with its tests.

* core: move cross-spawn-spawner to root and remove unused types

The cross-spawn-spawner module has been moved from src/effect/ to src/
to simplify the core package structure. The src/types.d.ts file which
contained unused type declarations has also been removed. All imports
throughout the codebase have been updated to reflect the new location.

This change reduces the package's internal complexity by flattening the
module hierarchy and removing dead code, making future maintenance easier.
