A profile's cron jobs now provably live in AND execute under that profile's
HERMES_HOME. A job authored under profile `coder` is stored at
`~/.hermes/profiles/coder/cron/jobs.json` and runs with coder's .env,
config.yaml, scripts and skills — never the default root's.
This was the de-facto behavior on main but only by accident: PR #50112 had
re-anchored cron storage at the shared default root, and a later stale-branch
squash merge (#52147) silently reverted it back to the profile home. Neither
direction was guarded by a test, so it could flip again on the next stale merge.
Changes:
- cron/jobs.py: document the per-profile storage anchor (get_hermes_home, NOT
get_default_hermes_root) and why anchoring at the root leaks
config/credentials/skills across profiles — the #4707 security boundary.
- cron/scheduler.py, cron/suggestions.py: same intent documented at the
dynamic resolution helper and the suggestions store.
- tests/cron/test_cron_profile_isolation.py: pin storage, lock-path, and
execution-home resolution to the active profile so a re-anchor can't regress.
Verified E2E: jobs created under two profiles land in separate per-profile
stores with zero cross-profile leakage and no shared-root store; scheduler
execution-home follows the active profile. Full cron suite: 576/576.
