feat: Functions — JS/TS execution with run log

core.functions + core.function_runs: project-scoped code executed by a
runtime binary on the backend host (bun or deno per function). Payload
arrives on stdin + PRIMORA_PAYLOAD env; stdout/stderr captured per run
(capped), with status/exit code/duration. Invoke returns 502 + the
recorded run on failure so errors stay observable.

Dashboard gains a Functions page: code editor, JSON payload invoke,
live result, run history. Runner config via FUNCTIONS_RUNTIME /
FUNCTIONS_TIMEOUT_SECONDS / FUNCTIONS_MAX_OUTPUT_BYTES.

Verified live: bun ran code, stdin payload delivered, error path returns
502 with captured stderr; timeout kills at deadline.
