Add --project flag to config set, config get, and config list CLI
commands, enabling per-project configuration overrides stored under
[project."<name>"] TOML tables in the global config file.
Project-scoped resolution slots between environment variable and global
levels in the ConfigService resolution chain. config list --project
shows only overrides for the named project with source annotations.
Implementation:
- ConfigService: add set_project_value() and get_project_overrides()
methods for TOML-backed project-scoped persistence and retrieval
- CLI config commands: wire --project flag through set, get, and list
subcommands; project-scoped list filters to overrides only
- Database persistence: project-scoped config stored as alternative
backend for projects not using TOML
- Documentation: update docs/reference/config_resolution.md with
project-scopable key lists, CLI examples, precedence diagram, and
non-scopable key rejection behavior
Tests:
- Behave: 12 BDD scenarios in features/config_project_scope.feature
covering set/get/list, precedence over global defaults, and
non-scopable key rejection
- Robot: 5 integration smoke tests in robot/config_project_scope.robot
for end-to-end project-scoped round-trip verification
- ASV: benchmarks/config_project_scope_bench.py measuring resolution
overhead with project scope active
All nox quality gates pass: lint, typecheck, unit_tests (7522 scenarios),
integration_tests (Config Project Scope suite passed), and coverage at
98% line rate (threshold 97%).
