feat(hooks): add tool-output-truncator for dynamic context-aware truncation

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.
