Piotr Szymaniak 378bcd69e3 tree: add AGENTS.md router and improve AI instruction files
Add AGENTS.md as a minimal router that directs AI agents to the
relevant instruction files based on what they are editing.

Improve the instruction files:

- cpp.instructions.md: clarify seastarx.hh scope (headers, not
  "many files"), explain std::atomic restriction (single-shard
  model, not "blocking"), scope macros prohibition to new ad-hoc
  only, add coroutine exception propagation pattern, add invariant
  checking section preferring throwing_assert() over SCYLLA_ASSERT
  (issue #7871)
- python.instructions.md: demote PEP 8 to fallback after local
  style, clarify that only wildcard imports are prohibited
- copilot-instructions.md: show configure.py defaults to dev mode,
  add frozen toolchain section, clarify --no-gather-metrics applies
  to test.py, fix Python test paths to use .py extension, add
  license header guidance for new files

# ScyllaDB — AI Agent Instructions
This file routes you to the relevant instruction files.
Do NOT load all files at once — read only what applies to your current task.
## Instruction Files
- `.github/copilot-instructions.md` — build system, test runner, code philosophy, test philosophy
- `.github/instructions/cpp.instructions.md` — C++ style, Seastar patterns, memory, error handling (for `*.cc`, `*.hh`)
- `.github/instructions/python.instructions.md` — Python style, testing conventions (for `*.py`)
## Which files to read
- **Always read** `.github/copilot-instructions.md` for build/test commands and project values
- **If editing C++ files** (`*.cc`, `*.hh`): also read `.github/instructions/cpp.instructions.md`
- **If editing Python files** (`*.py`): also read `.github/instructions/python.instructions.md`
