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).

Config `width` was position #3 in the detection chain, overriding all
dynamic detection (ioctl, process tree, stty, etc). This meant the
statusline couldn't adapt to terminal/pane resizes.
Now config `width` serves two roles:
- Max cap on dynamically detected widths (prevents absurd widths)
- Fallback when all dynamic detection methods fail
Also adds:
- ioctl on stderr (works when stdout is piped)
- stdin JSON `terminal_width` field for Claude Code to pass width
- Distinct diagnostic sources: config_cap, config_fallback, stdin_json

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)

Revised bd-3uw, bd-ywx, bd-62g, bd-4b1, bd-1if, bd-3ax from
score 3/5 to 4+/5 with concrete approach steps, code snippets,
TDD loops, and edge cases sourced from rust_prd.md.

- justify: gate DIM/RESET separator coloring on color_enabled param;
previously leaked ANSI escapes when --color=never or NO_COLOR was set
- vcs: apply branch name truncation per config (truncate.enabled,
truncate.max, truncate.style) for both git and jj renderers;
previously ignored truncate config causing long branch names to
overflow and trigger unnecessary priority drops
- flex: account for prefix/suffix overhead when computing context_bar
flex expansion width; previously double-applied apply_formatting
causing line to overshoot term_width when prefix/suffix configured

- output_style: use MAGENTA color per PRD (was incorrectly DIM)
- vcs: pass project dir to jj exec (was None, causing wrong cwd)
- tools: singular "tool" when count is 1 (was always "tools")
- layout: wire up apply_formatting() in render pipeline (prefix,
suffix, color override, pad, align were completely dead code)
