v0.4.0

Added

• Markdown-rendered pane output via glow (IR-013) — text replies, captain summaries, and tool-result bodies render through the glow terminal Markdown renderer, so bold, code blocks, tables, lists, and word-boundary wrapping reach the pane intact
• Catppuccin Mocha theme on the tmux-play session (IR-012) — truecolor pane borders carry the adapter accent (claude/codex/gemini/opencode), speaker prefixes carry per-speaker colors (boss blue, captain mauve, role adapter accent), error/aborted status bodies carry red/yellow, and a dedicated tool lifecycle prefix grammar replaces inline tool noise: tool> (caller-colored) for invocations, tool< for results with outcome-keyed ✓ / ✗ / · markers
• Real-glow acceptance suite — integration tests exercise the presenter against the actual glow binary, covering well-formed prefixed output, payload trailing-blank preservation, and no-stacked-blanks between turns
• query priority key in the tool_use input summary — search/fetch tools (ToolSearch wrappers and similar) surface the query text rather than falling through to compact JSON
• DR-005 design record for per-adapter permission configuration (typed PermissionPolicy through CligentOptions; no implementation in this release)

Changed

• Breaking: tmux-play requires glow on PATH in addition to tmux; the launcher fails fast with an install-pointing error when it is missing
• Breaking: the tool> invocation prefix is colored by the caller's adapter accent (mauve for captain, the adapter accent for a role) instead of a fixed peach; tool< keeps the outcome palette (green / red / yellow)
• Breaking: the overlay0 dim SGR around tool-result bodies is removed; styling is owned by glow's code-block rendering inside a payload-safe code fence (fence width chosen as max(3, longest_backtick_run + 1) so embedded fences cannot terminate it early)
• Text bodies now appear on block completion rather than streaming token-by-token. Markdown is not a streamable format (a renderer cannot tell whether subsequent bytes belong to an open code fence until the closing fence arrives); this is the deliberate tradeoff for word-boundary wrapping and inline-style rendering
• Pane width budget reserves the visible <who>> prefix when invoking glow, so prefixed first lines and indented continuations fit the pane without terminal-level rewrap
• Tool input summary truncation measures cells (CJK / emoji) rather than UTF-16 code units, so wide characters and surrogate-pair emoji never get split mid-codepoint
• README and docs/tmux-play.md Requirements lists updated to include glow
• CI acceptance job installs glow v2.1.2 before running acceptance tests

Fixed

• TTMUX-039 truecolor probe scoped to the server-side option probe; the attached-client #{client_termfeatures} check required a PTY harness not yet in place
• IR-013 review-flagged rendering edges: outer-margin trim bounded to at most one leading + one trailing blank (fenced-code frames and payload edge blanks survive); tool body strips exactly one trailing line terminator (intentional trailing blank rows survive); blank-line detection uses visible content (real glow emits space-padded structural rows); fallback path skips the outer-margin trim when glow render fails
• Speaker-prefix coloring keeps the continuation indent uncolored across streamed text-delta chunks that split an SGR opener across the wrap boundary
