Affaan Mustafa e41ee0c858 fix: resolve multiple reported issues (#205, #182, #188, #172, #173) (#207)
* fix: resolve multiple reported issues (#205, #182, #188, #172, #173)

- fix(observe.sh): replace triple-quote JSON parsing with stdin pipe to
  prevent ~49% parse failures on payloads with quotes/backslashes/unicode
- fix(hooks.json): correct matcher syntax to use simple tool name regexes
  instead of unsupported logical expressions; move command/path filtering
  into hook scripts; use exit code 2 for blocking hooks
- fix(skills): quote YAML descriptions containing colons in 3 skill files
  and add missing frontmatter to 2 skill files for Codex CLI compatibility
- feat(rules): add paths: filters to all 15 language-specific rule files
  so they only load when working on matching file types
- fix(agents): align model fields with CONTRIBUTING.md recommendations
  (opus for planner/architect, sonnet for reviewers/workers, haiku for
  doc-updater)

* ci: use AgentShield GitHub Action instead of npx

Switch from npx ecc-agentshield to uses: affaan-m/agentshield@v1
for proper GitHub Action demo and marketplace visibility.

# Python Patterns
> This file extends [common/patterns.md](../common/patterns.md) with Python specific content.
## Protocol (Duck Typing)
```python
from typing import Protocol
class Repository(Protocol):
def find_by_id(self, id: str) -> dict | None: ...
def save(self, entity: dict) -> dict: ...
```
## Dataclasses as DTOs
```python
from dataclasses import dataclass
@dataclass
class CreateUserRequest:
name: str
email: str
age: int | None = None
```
## Context Managers & Generators
- Use context managers (`with` statement) for resource management
- Use generators for lazy evaluation and memory-efficient iteration
## Reference
See skill: `python-patterns` for comprehensive patterns including decorators, concurrency, and package organization.
