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.
