Subject: [PATCH 1/5] fix: wire 4 missing CLI commands into cli-entry.ts (#237)

Add command routing for rc, copilot-bridge, init-remote, and rc-tunnel
which existed in packages/squad-cli/src/cli/commands/ but had no route
in cli-entry.ts. Also add help text entries for all four.

- rc / remote-control: starts RemoteBridge with --tunnel, --port, --path
- copilot-bridge: checks Copilot ACP stdio compatibility
- init-remote: standalone shorthand for init --mode remote <path>
- rc-tunnel: checks devtunnel CLI availability

aspire, link, loop, and hire were already wired.

Closes #237

Subject: [PATCH 2/5] feat: structured model preference & squad-level defaults
 (#223)

- Add ModelPreference interface (preferred, rationale, fallback) to builders/types.ts
- AgentDefinition.model now accepts string or ModelPreference object (backwards compatible)
- Add DefaultsDefinition with model field to SquadSDKConfig
- Add defineDefaults() builder function with validation
- Update charter generation to emit proper ## Model section with Preferred/Rationale/Fallback
- Charter generation applies squad defaults.model when agent has no model specified
- Update charter-compiler to extract rationale and fallback from ## Model section
- Export new types and defineDefaults from SDK entry point
- Update tests for build-command and charter-compiler

Closes #223

 - FRAMEWORK_WORKFLOWS already filters init to 4 safe workflows; the opt-in flag is about user control, not safety.
 - `process.env.NODE_NO_WARNINGS = '1'` set at runtime does NOT suppress Node.js ExperimentalWarning -- the env var is only checked at process start. Use a `process.emit` override to filter warnings at runtime.

+- CI failures in --version tests were caused by `node:sqlite` ExperimentalWarning leaking into terminal output (3 lines instead of 1). Fixed with process.emit hook in cli-entry.ts.
+### Model Config Pipeline - Issue #223 (2026-03-08)
+
+- The charter generation pipeline had a format mismatch: build.ts emitted **Model:** value (flat) but charter-compiler.ts parsed ## Model + **Preferred:** value (structured). Model preferences were silently lost in the round-trip.
+- Fix: AgentDefinition.model now accepts string or ModelPreference (backwards compatible). Build output uses proper ## Model section with Preferred, Rationale, Fallback lines.
+- Added DefaultsDefinition and defineDefaults() for squad-level model defaults. Agents without explicit model inherit from config.defaults.model.
+- The assertModelPreference() validator pattern (accept string or object, normalize internally) is reusable for any field that needs a simple-or-rich config shape.
+- Charter-compiler now extracts modelRationale and modelFallback in addition to modelPreference.
+- PR #245, branch squad/223-model-config.

+# Decision: Structured Model Preference in SDK Config
+
+**Date:** 2026-03-08
+**Author:** Fenster (Core Dev)
+**Issue:** #223
+**PR:** #245
+
+## Context
+
+Model preferences set via `defineAgent({ model: '...' })` were not reliably applied because the build pipeline emitted a flat `**Model:** value` line, but the charter-compiler expected a `## Model` section with `**Preferred:** value` format.
+
+## Decision
+
+1. **`AgentDefinition.model` accepts `string | ModelPreference`** — backwards compatible. A plain string is normalized to `{ preferred: string }` internally.
+2. **`ModelPreference` interface** has three fields: `preferred` (required), `rationale` (optional), `fallback` (optional).
+3. **Squad-level defaults** via `config.defaults.model` — applied to any agent that doesn't specify its own model preference.
+4. **Charter output** uses the `## Model` section format with `**Preferred:**`, `**Rationale:**`, `**Fallback:**` lines — matching what the charter-compiler already parses.
+
+## Impact
+
+- All agents: charter generation now reliably round-trips model preferences.
+- Verbal/Keaton: the 4-layer model selection hierarchy documented in squad.agent.md is now supported at the SDK config level.
+- Anyone adding new config fields: use the `assertModelPreference()` pattern (accept string-or-object, normalize internally) for fields that need simple and rich config shapes.

Subject: [PATCH 4/5] test: add tests for 8 untested CLI commands + wiring
 regression test

Add test coverage for all 8 CLI commands that had zero tests:
- link (10 tests): validation, fs operations, gitignore handling
- init-remote (8 tests): config structure, relative paths, idempotency
- watch (6 tests): module exports, reportBoard pure function
- start (3 tests): module exports, function arity
- rc-tunnel (10 tests): exports, getMachineId, getGitInfo, devtunnel availability
- extract (5 tests): exports, error handling for missing/invalid config
- copilot (6 tests): exports, error on missing squad dir, add/remove flow
- copilot-bridge (8 tests): class instantiation, lifecycle, safe-before-init

Add command wiring regression test (21 tests) that verifies every .ts
file in commands/ has a corresponding route in cli-entry.ts, preventing
the recurring unwired command bug class (issues #224, #236, #237).

Add subpath exports to squad-cli package.json for the 6 commands that
were missing package exports (watch, start, rc-tunnel, extract, copilot,
copilot-bridge).

Total: 77 new tests, all passing.
