Root cause: DEFAULT_TARGET_MAX_TOKENS (50k tokens ~200k chars) was too high
for webfetch outputs. Web pages can be large but most content doesn't exceed
this limit, so truncation rarely triggered.
Changes:
- Add WEBFETCH_MAX_TOKENS = 10k tokens (~40k chars) for web content
- Introduce TOOL_SPECIFIC_MAX_TOKENS map for per-tool limits
- webfetch/WebFetch now use aggressive 10k token limit
- Other tools continue using default 50k token limit
- Add comprehensive tests for truncation behavior
Fixes#195

- Changed truncate_all_tool_outputs default from false to true
- Updated schema documentation to reflect new default
- Added entry in README experimental features table
- Regenerated JSON schema
This prevents prompts from becoming too long by dynamically
truncating output from all tool calls, not just whitelisted ones.
Feature is experimental and enabled by default to help manage
context window usage across all tools.

The grep-output-truncator hook was never registered in index.ts, so grep
output was not being truncated since commit 03a4501 which removed grep/Grep
from tool-output-truncator's TRUNCATABLE_TOOLS list.
- Remove unused grep-output-truncator.ts
- Add "grep" and "Grep" back to tool-output-truncator's TRUNCATABLE_TOOLS

Add a new tool for managing tmux sessions with automatic tracking and cleanup:
- interactive_bash tool: Accepts tmux commands via tmux_command parameter
- Session tracking hook: Tracks omo-* prefixed tmux sessions per OpenCode session
- System reminder: Appends active session list after create/delete operations
- Auto cleanup: Kills all tracked tmux sessions on OpenCode session deletion
- Output truncation: Registered in TRUNCATABLE_TOOLS for long capture-pane outputs

Tool names in builtinTools are lowercase ('grep', 'glob') but truncator
hooks were checking for capitalized names ('Grep', 'Glob'), causing
truncation to never trigger and resulting in context window overflow.

Refactor grep-output-truncator into a general-purpose tool-output-truncator
that applies dynamic truncation to multiple tools based on context window usage.
Truncated tools:
- Grep, safe_grep (existing)
- Glob, safe_glob (new)
- lsp_find_references (new)
- lsp_document_symbols (new)
- lsp_workspace_symbols (new)
- lsp_diagnostics (new)
- ast_grep_search (new)
Uses the new dynamic-truncator utility from shared/ for context-aware
output size limits based on remaining context window tokens.
