Agent Improvements

Progressive context clearing tiers — Three-tier context management: tool-result clearing at 75% threshold, tool-use input clearing for large arguments, and LLM-based compaction at 88%. Purely mechanical clearing operations run without LLM calls, saving tokens cost-effectively.
Semantic repetition detection — New repetitionTracker detects failed edit clusters on the same file (3/5/7 failure escalation) and read-edit-fail cycles. Prevents infinite near-miss loops that exact-match loop detection misses.
Deterministic overseer — Trajectory analysis agent that monitors for tool spam, read-only stalls, file-stuck patterns, error escalation, and task drift. Injects targeted guidance messages when pathological patterns are detected.
Async auto-verify — Build verification now runs asynchronously instead of blocking the agent loop, allowing continued work during compilation.
Makefile-aware build detection — Auto-verify now detects build systems (Makefile, npm scripts, cargo, etc.) and suggests appropriate verification commands.
Incomplete todo check — Agent checks for incomplete todos before finishing and prompts to complete them.

Model panel: context window and max tokens editing — Users can now directly edit context window and max tokens values in the model panel with K/M/G suffix support (e.g., 256k, 1M, 2G).
Model panel field overwrite fix — Fixed a bug where editing context window would silently drop the value due to premature field clearing.
Model panel focus management — Input blur on panel open, focus restoration on close for smoother UX.

mobile_device multi-platform listing — devices action now lists both iOS and Android when platform=auto, instead of only showing one platform.
mobile_device multi-device support — Transport ID targeting for operations on specific Android devices, with stale cache cleanup.
read_file line count — Reports total line count in truncation messages and large-file errors.
glob result sorting — Results are now sorted alphabetically and capped at 500 matches.
run_command line-aware truncation — Output truncation preserves line boundaries.
edit_file fuzzy diagnostics — Shows nearest-match suggestions when exact text matching fails.
web_fetch content-aware extraction — Improved HTML-to-text extraction.

Session index fsync — saveIndex() now uses Create+Write+Sync+Close+Rename pattern (matching Save()) for crash durability. Previously used WriteFile without fsync, risking empty/partial index on crash.
Session Save fsync — Added f.Sync() before atomic rename in Save() for crash durability.
Temp image cleanup — cleanupOldTempImages() removes files older than 24h from $TMPDIR/ggcode-images/ on TUI startup, preventing unbounded disk usage.
Tunnel image persistence — Mobile-sent images are now persisted to temp directory with proper sourcePath, fixing a bug where the agent couldn't locate image files.

Anthropic prompt caching — System prompt and tools are now cached using Anthropic's prompt caching feature, reducing latency and token costs for Anthropic models.
A2A push notification timeout — Added 10s timeout to push notification HTTP requests to prevent hanging.
Session-scoped model/vendor persistence — Model and vendor changes are now saved per-session instead of globally, matching the existing permission mode pattern.

OOM prevention — CI and verify-ci now use -p 1 sequential execution and memory limits to prevent OOM kills.
Integration test tagging — Heavy external-dependency tests tagged with integration_local to exclude from default CI runs.
LSP test resilience — Tests now skip gracefully when external language servers fail to initialize.
safego.Go fixes — Replaced bare goroutines with safego.Go() for panic recovery.

Image sending — Mobile app can now send images to the desktop agent. Images are properly persisted to temp directory for agent access.
