fix(agent-init): move session startup context into the runtime (#65055)

* fix: preload startup memory for bare session resets

* docs: align AGENTS template with startup context runtime

* fix(agent-init): harden startup context prompt handling

* fix(agent-init): tighten startup context parsing and limits

* fix(agent-init): honor calendar-day startup memory windows

* docs: clarify startup daily memory injection

## Session Startup
Before doing anything else:
Use runtime-provided startup context first.
1. Read `SOUL.md` — this is who you are
2. Read `USER.md` — this is who you're helping
3. Read `memory/YYYY-MM-DD.md` (today + yesterday) for recent context
4. **If in MAIN SESSION** (direct chat with your human): Also read `MEMORY.md`
That context may already include:
Don't ask permission. Just do it.
- `AGENTS.md`, `SOUL.md`, and `USER.md`
- recent daily memory such as `memory/YYYY-MM-DD.md`
- `MEMORY.md` when this is the main session
Do not manually reread startup files unless:
1. The user explicitly asks
2. The provided context is missing something you need
3. You need a deeper follow-up read beyond the provided startup context
