Major changes:
- **Bedrock translator architecture**: Extract orchestration logic from `impl.rs` into
a dedicated `translator.rs` module. Rename `convert_request.rs` → `request_translator.rs`
and `stream.rs` → `response_translator.rs` for clarity. Remove `tool_docs.rs` (inlined).
Remove `fallback_to_warp` setting and server fallback path — Bedrock is now the sole backend.
- **Unknown tool handling**: The response translator now detects hallucinated/unknown tool
calls from the model and synthesizes error tool_results so the conversation doesn't
deadlock waiting for a result that will never come.
- **Usage display overhaul**: Replace credit-based usage display with detailed token metrics
showing context window %, cache hit rate (read/write/miss), and estimated cost in dollars.
Add `total_input_tokens`, `total_cache_read_tokens`, `total_cache_write_tokens`, and
`cache_miss_tokens` accessors to `AIConversation`.
- **Predefined rules system**: Add `predefined_rules.rs` with 11 system-defined behavioral
rules that are auto-seeded on first launch. Add "Add Predefined Rules" button to the
Rules UI for re-adding them later. Track seeding state via `has_seeded_predefined_rules`
setting.
- **Session restore improvements**: Rename database file from `warp.sqlite` to
`galaxy.sqlite` with automatic migration from both same-directory and state_dir legacy
paths. Improve CWD persistence by falling back to `session_startup_path` for agent-mode
and fresh tabs. Add extensive session-save/restore logging.
- **Shell bootstrap rebrand**: Rename `WARP_INITIAL_WORKING_DIR` environment variable to
`GALAXY_INITIAL_WORKING_DIR` across bash, zsh, and fish bootstrap scripts.
- **Model defaults**: Change default Bedrock model from Opus 4.7 to Opus 4.6.
Add `context_window_for_model()` helper with model-aware context sizes.
Remove `is_bedrock_model()` (no longer needed without server fallback).
- **User query persistence**: The response translator now emits a `UserQuery` proto message
at stream start so the user's prompt persists across sessions for conversation titles.

Bedrock was calling suggest_next_prompt tool which created a SuggestPrompt
action that waited forever on a oneshot channel for UI interaction that
never fires in the Bedrock path, keeping the conversation permanently
InProgress. Fixed by filtering the tool from the Bedrock tool list and
skipping it at the stream level when the LLM calls it from context history.
Also includes: Bedrock cache token tracking, cost estimation, LSP
improvements, conversation usage view updates, and external config support.
