amosblomqvist cb4fe25c89 wave 2 (platform stream): settings storage & plumbing foundation (P2)
- src/core/settings.ts: versioned DELTA record schema + sanitizer (unknown keys preserved)
  — general/chat/agent{models,tools,prompts}/appearance/graph sections
- src/core/settings-resolution.ts: pure resolveSettings (factory defaults → user delta),
  extraction/graph-context channel predicates
- src/store/settings.ts + prompt-overrides.ts: SettingsStore/PromptOverrideStore adapters
  wired through stores.ts (effectiveSettings() fresh per call); lazy migration of
  default-settings.json into record.chat
- app/api/settings/** routes (record, section bodies, prompt overrides per segment)
- chat-handler: graph gates at trigger call-sites + toolToggles injection seam
- config.ts: SETTINGS_FILE + PROMPTS_OVERRIDE_DIR paths

/**
* PUT/DELETE /api/settings/prompts/[...segment] — the override TEXT for
* one prompt segment (settings-storage wave, 2026-09-19).
*
* PUT body {text} → writes data/prompts/<segment path mirror>. 200.
* The segment must be a CURRENT source segment (allSegmentPaths
* — derived from src/agent/prompts at runtime): overriding a
* segment that doesn't compose is a typo or a vanished fragment,
* a 400, never a silent orphan.
* DELETE → removes the override file (idempotent). Switches are NOT
* touched — an on-switch with no file composes the source
* default (inert by design), so the user's switch state survives
* a delete/re-write cycle.
*
* The ON/OFF switch itself lives in the record's agent.prompts map
* (PUT /api/settings/agent) — file presence alone is never the override.
