relayburn-cli: burn summary + hotspots presenters (#248 D1)

[willwashburn]

Summary

• Implement burn summary and burn hotspots as thin presenters over relayburn_sdk::summary / ::hotspots, matching the TS CLI flag set + output byte-for-byte.
• Un-ignore the summary / summary-json / hotspots / hotspots-json golden invocations.

Test plan

• cargo test --workspace
• BURN_GOLDEN=1 cargo test --test golden -p relayburn-cli (4 entries pass)
• burn summary --help / burn hotspots --help match TS flag set

📝 Walkthrough

Walkthrough

The PR implements two CLI commands (summary and hotspots) as thin presenters over relayburn-sdk. It introduces payload-bearing Command enum variants with per-command argument structs, adds full implementations with JSON and human-readable output formatting, includes formatting helpers aligned with the TypeScript CLI, updates test infrastructure to bootstrap SQLite from JSONL ledger events, and enables corresponding golden test invocations.

Changes

Summary and Hotspots CLI Commands

Layer / File(s)	Summary
CLI Argument Shape crates/relayburn-cli/src/cli.rs, crates/relayburn-cli/src/commands/summary.rs, crates/relayburn-cli/src/commands/hotspots.rs	Summary and Hotspots enum variants converted from unit-like to payload-bearing, carrying SummaryArgs and HotspotsArgs structs respectively. Each Args struct declares per-command flags (since, project, session, provider, by-tool, by-subagent-type, etc.).
Core Command Logic crates/relayburn-cli/src/commands/summary.rs	Implements full summary workflow: opens ledger, ingests sessions, builds queries, aggregates by model or provider, computes cost/fidelity/replacement-savings via SDK, and routes to JSON or human output. Validates flag mutual exclusivity and deprecated features.
Core Command Logic crates/relayburn-cli/src/commands/hotspots.rs	Implements full hotspots workflow: opens ledger, ingests data, computes per-source coverage breakdown, fetches hotspots via SDK, and renders output in JSON or human-readable format with per-file, per-bash, per-subagent detail.
Output Formatting Infrastructure crates/relayburn-cli/src/render/format.rs, crates/relayburn-cli/src/render/mod.rs	Adds formatting helpers (format_usd, format_int, format_uint, render_table, coerce_whole_f64_to_int) matching TS CLI style; modularized into new format.rs and exported via mod.rs.
JSON & Human Rendering crates/relayburn-cli/src/commands/summary.rs, crates/relayburn-cli/src/commands/hotspots.rs	Both commands include separate emit_json and emit_human entrypoints with JSON serialization helpers (cost_breakdown_to_json, fidelity_summary_to_json, replacement_savings_to_json, etc.) and rich human-readable table rendering with coverage markers, notices, and per-row metrics.
Dispatch & Integration crates/relayburn-cli/src/main.rs, crates/relayburn-sdk/src/lib.rs, crates/relayburn-cli/Cargo.toml	Main.rs dispatch logic destructures payload from Command variants and passes to updated run() signatures. SDK exports new AggregateByProviderOptions type. Cargo.toml adds indexmap dependency with serde feature.
Test Bootstrap & Enablement crates/relayburn-cli/tests/golden.rs, crates/relayburn-cli/tests/smoke.rs, tests/fixtures/cli-golden/invocations.json, tests/fixtures/cli-golden/ledger/.gitignore	Adds bootstrap_sqlite_from_jsonl() to replay ledger.jsonl into SQLite; normalizes tool_result events and constructs Stamps for SDK ingestion. Smoke tests updated to track UNIMPLEMENTED_SUBCOMMANDS separately. Four golden invocations (summary, summary-json, hotspots, hotspots-json) moved from disabled to enabled. .gitignore expanded to cover content.sqlite and archive.sqlite variants.
Documentation CHANGELOG.md	Unreleased entry documents relayburn-cli wiring to relayburn-sdk with thin presenter pattern, parity with TS CLI flags and stdout behavior, and golden test enablement.

Poem

🐰 A hop and a squeal—the presenters arise!
From thin wires to tables, with cost-column eyes,
JSON flows softly, humanity shines,
Bootstrap the ledger in SQLite's lines!
Four golden tests now skip no more—
Relayburn-cli stats adorn the store! ✨

💡 Codex Review

Preserve source attribution in hotspots coverage notice

The coverage notice hard-codes a single source label (codex vs claude-code) from aggregate missing-field stats, so any slice with excluded turns from multiple source kinds will produce a misleading explanation (for example, excluded Claude and OpenCode turns can still be reported as only codex). This affects user diagnosis of why attribution was excluded because the message no longer matches the actual source mix that hotspots processed.

[willwashburn]

Addressed in e50f490 — the hotspots presenter now re-walks the matched-window turns itself to build a per-SourceKinddescribeExcluded-style breakdown, then renders one inline clause per source joined with " and " (same shape as the TS CLI). This drops the brittle "any tool-result-events missing → codex; otherwise claude-code" heuristic the previous version used. JSON output is unchanged (the TS --json shape doesn't carry the per-source breakdown).
