* fix(ai): update spoofed Gemini CLI User-Agent to v0.35.3 format
Gemini CLI v0.35+ changed its User-Agent format:
- Dropped 'google-api-nodejs-client/10.5.0' suffix
- Added surface field (third param in parens)
- New format: GeminiCLI/VERSION/MODEL (PLATFORM; ARCH; SURFACE)
The stale v0.34.0 UA was contributing to google-gemini-cli/gemini-3.1-pro-preview
being rejected, alongside Google's new abuse detection for third-party CCA usage
(google-gemini/gemini-cli#22970).
Verified: model responds successfully with updated UA.
* feat(scripts): add spoofed version drift checker
Fetches latest stable release from google-gemini/gemini-cli GitHub
releases and compares against the hardcoded version in the provider.
bun check-spoofed-versions # report drift, exit 1 on mismatch
bun check-spoofed-versions --update # apply version bump in-place
Extensible for additional spoofed tools (Antigravity, Copilot headers).
- Introduced Effort enum and ThinkingConfig metadata for per-model reasoning capabilities with min/max effort levels.
- Migrated thinking level API from string-based ThinkingLevel to structured Effort enum across agent and AI packages.
- Added model-thinking module with effort mapping, policy application, and semantic versioning utilities for provider-specific thinking modes.
- Removed supportsXhigh() function and replaced effort clamping with model-aware validation using ThinkingConfig metadata.
- Expanded models.json with thinking configuration objects for 50+ models including Claude, Gemini, and OpenAI variants.
- Added Python analysis scripts for edit tool usage patterns and tool invocation stream processing.
- Added sync-exports.ts script to enforce canonical package.json field ordering and auto-generate exports from filesystem structure.
- Expanded subpath exports across 11 packages (ai, agent, coding-agent, natives, stats, utils, tui, swarm-extension) to enable flexible module imports.
- Reorganized package.json field ordering to follow standard conventions with metadata before main/exports and files/exports at end.
- Consolidated wildcard export patterns to simplify import paths while maintaining backward compatibility with explicit subpath exports.
bun resolves transitive deps from the npm registry even when all
packages are provided as local tarballs. Since 12.15.0 isn't published
yet, these lookups fail. Adding overrides in package.json forces bun
to resolve all @oh-my-pi/* packages from the local tarballs.
The coding-agent tarball depends on @oh-my-pi/pi-ai@12.15.0 etc. which
aren't published yet. Two separate bun add calls caused the second to
resolve deps against npm instead of the already-installed local tarballs.
- Added support for braced escape sequences (\p{...}, \P{...}, \x{...}, \u{...}) in regex pattern sanitization to properly preserve unicode property escapes and hex escapes.
- Improved LSP client message writing by simplifying header encoding and refactoring abort signal handling with the untilAborted utility.

- Added automatic AVX2 CPU detection on Linux, macOS, and Windows platforms to select appropriate native addon variant at runtime.
- Updated native addon filename scheme to include CPU variant suffix (e.g., pi_natives.linux-x64-modern.node) for x64 platforms.
- Updated CLI update mechanism to support downloading and installing multiple native addon variants per platform with fallback support.
- Removed fallback untagged pi_natives.node binary creation; platform and variant-tagged binaries are now required.

- Reordered constant declarations to ensure TMP_DIR is initialized before CLI_PATH which depends on it.
- Updated scripts/repro-stuck.ts to use consistent CLI path resolution with Bun.fileURLToPath().
