docs(hermes): stacked system messages — system_blocks kwarg (PR #499)
- Add '## Advanced: stacked system messages' section (before Capability table)
covering: usage, block ordering (persona → tools → reasoning), None/empty
skip behaviour, system_blocks-vs-system_prompt precedence, backward compat note
- Update shipped capability table to include stacked system messages row and
note PR #499 alongside Phase 2a/2b/2c
Pairs with monorepo PR #798 (feat(hermes): stacked system messages —
persona + tools + reasoning policy, PR #499).
⚠ Depends on docs PR #9 (hermes.mdx baseline) merging first.
