* feat(config): add experimental config schema for gating unstable features
This adds a new 'experimental' config field to the OhMyOpenCode schema that enables fine-grained control over unstable/experimental features:
- aggressive_truncation: Enables aggressive token truncation in anthropic-auto-compact hook for more aggressive token limit handling
- empty_message_recovery: Enables empty message recovery mechanism in anthropic-auto-compact hook for fixing truncation-induced empty message errors
- auto_resume: Enables automatic session resume after recovery in session-recovery hook for seamless recovery experience
The experimental config is optional and all experimental features are disabled by default, ensuring backward compatibility while allowing early adopters to opt-in to cutting-edge features.

Add new hook that uses the `experimental.chat.messages.transform` hook to prevent 'non-empty content' API errors by injecting placeholder text into empty messages BEFORE they're sent to the API.
This is a preventive fix - unlike session-recovery which fixes errors after they occur, this hook prevents the error from happening by sanitizing messages before API transmission.

Directly modify empty text parts in storage files before attempting
to inject new parts. This ensures that existing empty text parts are
replaced with placeholder text, fixing the issue where Anthropic API
returns 'messages.X: all messages must have non-empty content' error
even after recovery.
- Added replaceEmptyTextParts function to directly replace empty text parts
- Added findMessagesWithEmptyTextParts function to identify affected messages
- Modified recoverEmptyContentMessage to prioritize replacing existing empty parts

- Add storage.ts: Functions to find and truncate largest tool results
- Add TruncateState and TRUNCATE_CONFIG for truncation tracking
- Implement truncate-first recovery: truncate largest output -> retry (10x) -> compact (2x) -> revert (3x)
- Move session error handling to immediate recovery instead of session.idle wait
- Add compactionInProgress tracking to prevent concurrent execution
This fixes GitHub issue #63: "prompt is too long" errors now trigger immediate recovery by truncating the largest tool outputs first before attempting compaction.

The previous Windows implementation used System.Windows.Forms.MessageBox
which displays a blocking modal dialog requiring user interaction.
This replaces it with the native Windows.UI.Notifications.ToastNotificationManager
API (Windows 10+) which shows a non-intrusive toast notification in the corner,
consistent with macOS and Linux behavior.
- Uses native Toast API (no external dependencies like BurntToast)
- Non-blocking: notification auto-dismisses
- Graceful degradation: silently fails on older Windows versions
- Fix escaping for each platform (PowerShell: '' for quotes, AppleScript: backslash)
- Use os.tmpdir() instead of hardcoded /tmp for cross-platform temp files
- Use os.homedir() with USERPROFILE fallback for Windows home directory
- Disable forceZsh on Windows (zsh not available by default)

Add pattern matching for 'content...is empty' format to detectErrorType function
in session-recovery hook. This fixes detection of Anthropic API errors like
'The content field in the Message object at messages.65 is empty'.
Previously only caught 'non-empty content' and 'must have non-empty content'
patterns, missing this actual API error format.

- Add FallbackState interface to track message removal attempts
- Implement getLastMessagePair() to identify last user+assistant message pair

- Configure max 3 revert attempts with min 2 messages requirement
- Trigger fallback after 5 compaction retries exceed
- Reset retry counter on successful message removal for fresh compaction attempt

Resolves: When massive context (context bomb) is loaded, compaction fails and session becomes completely broken. Now falls back to emergency message removal after all retry attempts fail, allowing session recovery.

Instead of blocking commands via regex pattern matching (which caused false
positives like 'startup', 'support'), now wraps all bash commands with:
- CI=true
- DEBIAN_FRONTEND=noninteractive
- GIT_TERMINAL_PROMPT=0
- stdin redirected to /dev/null
TUI programs (text editors, system monitors, etc.) are still blocked as they
require full PTY. Other interactive commands now fail naturally when stdin
is unavailable.

Implements hook that tracks whether explore/librarian agents have been used in a session.
When target tools (Grep, Glob, WebFetch, context7, websearch_exa, grep_app) are called
without prior agent usage, appends reminder message recommending parallel background_task calls.
State persists across tool calls and resets on session compaction, allowing fresh reminders
after context compaction - similar to directory-readme-injector pattern.
