feat(config): load-config verb, partial-load rendering, demo examples#106
Merged
Conversation
Three coupled additions: 1. **VERB_LOAD_CONFIG** — new verb + `SESSION_CONFIG_OVERRIDE_KEY`: a click writes a per-session config-file path into SessionState; the render path reads it at the cache-lookup boundary so the next request uses the overridden file without restarting the daemon. 2. **Partial-load rendering** — variable declaration failures accumulate as `loadWarnings` (non-fatal) rather than aborting the config load; segment render wraps in try/catch and returns a ⚠ error cell for any segment that fails, keeping the rest of the bar alive. Together these let a config switch succeed even when the new config has broken variables — working segments render, broken ones show an error cell. 3. **`coerceToType` for git var defaults** — string "0" is coerced to number 0 for number-typed git fields, matching the behaviour of the live-fetch projection path. Also adds `examples/demo-actions.json5` and `examples/demo-variables.json5` — comprehensive demo configs exercising the full surface of each subsystem, with `CC_CANDYBAR_CONFIG=examples/… pnpm demo` instructions inline.

Adversarial review
The diff introduces VERB_LOAD_CONFIG, partial-load rendering via loadWarnings accumulation, coerceToType for git-var defaults, and two demo configs. The architecture is sound: the verb handler validates its wire value at the boundary, the render-time try/catch correctly isolates broken segments, and the warning reset in reloadInto (entry.lastWarning = detectConfigCollisions(...) at line 207) fires before the new append block so stale warnings do not persist across reloads. VERBS is constructed via spread of LEAF_VERBS so the new verb is automatically dispatched. No correctness defects were found after checking callers and contracts.

Summary
VERB_LOAD_CONFIG— new click verb that stores a per-session config-file path inSessionState; the daemon reads it at the render cache-lookup boundary so the override takes effect on the next tick without a daemon restart.registerDslConfignow accumulate asloadWarnings(non-fatal advisory warnings) instead of aborting the load; segment render bodies wrap in try/catch and return a⚠ name: …error cell for any segment that fails at render time, keeping all other segments alive. Together these make config switching graceful: a broken new config renders what it can, surfaces what it can't.coerceToTypefor git var defaults — fixes type coercion forstringdefaults onnumber-typed git fields ("0"→0), matching the live-fetch projection path.examples/directory —demo-actions.json5anddemo-variables.json5: comprehensive demo configs exercising the full surface of actions/layout/groups and all variable source kinds respectively, usable standalone viaCC_CANDYBAR_CONFIG=examples/… pnpm demo.Test plan
