* feat(cron): add headless code-mode driver and trigger-script evaluator
Part A of cron event triggers: runCodeModeScriptHeadless runs a script
to completion (exec/settle/resume, no snapshots, no session), plus the
cron-facing evaluator with per-job tool catalog cache, semaphore, 16KB
state cap, and closed failure taxonomy.
* fix(cron): correct trigger-script bootstrap flags and cache narrowing
* feat(cron): add event triggers (polled condition-watcher scripts)
Part B: trigger field on cron jobs gated by cron.triggers.enabled;
timer evaluates the script each due tick, quiet ticks leave no run
history, fired runs append the script message to the payload; once
semantics, min-interval floor, SQLite columns, RPC/CLI/agent-tool
surfaces, and docs.
* fix(cron): propagate triggerEval through startup catch-up outcomes
* fix(cron): honor cron staggering on quiet trigger ticks; fix trigger test types
* fix(cron): reject with Error reason in trigger-script abort test
* fix(cron): regenerate protocol/docs/snapshot artifacts and break madge cycle for trigger types
CI fixes for #101195: trigger evaluator result types move to the cron
types leaf (madge cycle), cron tool schema inventory gains trigger,
Swift protocol bindings + docs map + Linux prompt snapshots regenerated.
* fix(cron): drop underscore-dangle names in trigger code sync assert
* fix(cron): adopt registerHeadlessToolSearchCatalog after tool-search symbol localization
Upstream #101831 made registerToolSearchCatalog module-private; fold the
headless ref-only catalog registration into one public seam.
