Fix Python SDK authorization and resource paths

[0xMassi]

Adds a backward-compatible ScopeError for HTTP 403, preserves status 403, percent-encodes every opaque path identifier, and adds sync/async coverage. All 136 tests pass on Python 3.14.

Summary by CodeRabbit

• New Features

  • Added ScopeError for 403 responses when an account lacks required permissions or plan access.
  • Preserved compatibility by making ScopeError an AuthenticationError subtype.
  • Improved handling of IDs containing spaces and special characters in API requests.

• Documentation

  • Clarified authentication and permission-related errors, including X monitoring behavior.

• Tests

  • Added coverage for permission errors and special-character IDs.

• Chores

  • Strengthened CI workflow security and reproducibility.

📝 Walkthrough

Walkthrough

The client now raises ScopeError for 403 responses, preserves AuthenticationError compatibility, and percent-encodes opaque identifiers in request paths. The package exports the new exception. CI permissions and action references are hardened. Documentation and tests reflect these changes.

Changes

Client behavior updates

Layer / File(s)	Summary
Scope error classification and exposure webclaw/errors.py, webclaw/client.py, webclaw/__init__.py, tests/test_async_client.py, tests/test_client.py, tests/test_x.py, README.md	403 responses raise ScopeError with status code 403. ScopeError remains catchable as AuthenticationError, while 401 responses use AuthenticationError. Tests and documentation cover the distinction.
Opaque identifier path encoding webclaw/_endpoints.py, webclaw/client.py, webclaw/async_client.py, tests/test_client.py	Job, watch, and monitor identifiers pass through path_segment() before insertion into request paths. Tests cover spaces, slashes, and question marks.

CI workflow hardening

Layer / File(s)	Summary
Workflow permissions and action references .github/workflows/ci.yml	The workflow grants read-only contents access and pins checkout and Python setup actions to commit SHAs.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to ae246

The SDK changes improve authorization errors and path encoding, but the pull-request CI workflow still exposes a persisted read-only repository token to repository-controlled commands, creating a bounded credential-exposure risk. The documentation example also reports 403 scope failures as invalid credentials. Merge should wait for these issues to be corrected or explicitly accepted by the owner.
