- Replaced tool-based `set_title` invocation with XML-style `<title>` marker tags for session title discovery.
- Implemented robust JSON-unwrapping logic to handle and sanitize title generation outputs.
- Updated model registry in catalog with new model support, provider prefixes, and metadata adjustments.
- Synchronized system prompt documentation and test suites to reflect the new marker-based generation flow.
- add discovery of `TITLE_SYSTEM.md` and pass it through interactive startup context
- route custom title prompts to online and local tiny title generators via protocol
- update session-title docs and changelog with override behavior
- add tests for prompt discovery, forwarding, and fallback to bundled title prompts
- Added guidance that generated skills/rules/tool inventory live in prompt block 0.
- Documented APPEND_SYSTEM.md as the supported way to customize while preserving automatic skill discovery.
- Noted that SYSTEM.md users must hard-code skill instructions if they replace block 0.
Fixes#1671
- Removed the (walk-up) annotation on project SYSTEM.md lookup.
- Documented that findConfigFile only checks <cwd>/.omp etc., not ancestors.
- Clarified that the capability-layer walk-up exists but its output is never rendered by the default template under normal CLI startup.
Fixes#1671
- Documented that CLI SYSTEM.md replaces only prompt block 0 and keeps defaultPrompt.slice(1).
- Clarified append prompt ordering with and without a custom system prompt.
- Corrected deduplication wording to distinguish CLI block replacement from internal buildSystemPrompt dedupe.
Fixes#1671
- Added docs/system-prompt-customization.md covering precedence,
replace-vs-append semantics, the verbatim insertion rule for
template syntax, deduplication, and discovery behavior across
the primary findConfigFile path and the capability layer.
- Linked the new doc from docs/config-usage.md so the existing
SYSTEM.md reference points at the full contract.
Fixes#1671
