Infrastructure layer for the TUI visual overhaul. Introduces foundational
modules and capabilities that the section-level features build on:
colorgrad (0.7) dependency:
OKLab gradient interpolation for per-character color transitions in
sparklines and context bars. Adds ~100K to binary (929K -> 1.0M).
color.rs expansion:
- parse_hex(): #RRGGBB and #RGB -> (u8, u8, u8) conversion
- fg_rgb()/bg_rgb(): 24-bit true-color ANSI escape generation
- gradient_fg(): two-point interpolation via colorgrad
- make_gradient()/sample_fg(): multi-stop gradient construction and sampling
- resolve_color() now supports: hex (#FF6B35), bg:color, bg:#hex,
italic, underline, strikethrough, and palette refs (p:success)
- Named background constants (BG_RED through BG_WHITE)
transcript.rs (new module):
Parses Claude Code transcript JSONL files to derive tool use counts,
turn counts, and per-tool breakdowns. Claude Code doesn't include
total_tool_uses or total_turns in its JSON — we compute them by scanning
the transcript. Includes compact cache serialization format and
skip_lines support for /clear offset handling.
terminal.rs (new module):
Auto-detects the terminal's ANSI color palette for theme-aware tool
coloring. Priority chain: WezTerm config > Kitty config > Alacritty
config > OSC 4 escape sequence query. Parses Lua (WezTerm), key-value
(Kitty), and TOML/YAML (Alacritty) config formats. OSC 4 queries
use raw /dev/tty I/O with termios to avoid pipe interference. Includes
cache serialization helpers for 1-hour TTL caching.
input.rs updates:
- All structs now derive Serialize (for --dump-state diagnostics)
- New fields: transcript_path, session_id, cwd, vim.mode, agent.name,
exceeds_200k_tokens, cost.total_api_duration_ms
- CurrentUsage: added input_tokens and output_tokens fields
- #[serde(flatten)] extras on InputData and CostInfo for forward compat
cache.rs:
Added flush_prefix() for /clear detection — removes all cache entries
matching a key prefix (e.g., "trend_" to reset all sparkline history).

1. cache: record diagnostic miss before early-return on modified()/duration_since() failure
2. dump-state: resolve all cache_dir template vars ({cache_version}, {config_hash})
3. config: remove dead breakpoint_hysteresis field from GlobalConfig (breakpoints.hysteresis is used)
4. config: align Rust Default cache_dir with defaults.json template
5. vcs: apply branch truncation in render_stale_cache (--no-shell path)
6. vcs: fix jj prefetch retry on already-failed command (flatten→unwrap_or_else)
