feat(cli): wire project context CLI stubs to ACMS pipeline

Wire all four project context CLI commands (inspect, simulate, set, show)
to live ACMS pipeline services via ContextTierService and CRP models.

- context inspect: queries ContextTierService for tier metrics and
  per-project fragments with filtering by strategy/focus/breadth/depth
- context simulate: dry-run context assembly using CRP models with
  configurable token budget and assembly strategies
- context set: 12 new ACMS pipeline options (hot_max_tokens,
  warm_max_decisions, cold_max_decisions, summary_max_tokens,
  temporal_scope, auto_refresh, focus_area, breadth, depth,
  assembly_strategy, retrieval_strategy, summary_strategy)
- context show: displays ACMS pipeline configuration alongside policy

- `context inspect` displayed global tier fragment counts (hot/warm/cold)
across all projects instead of counts for the target project only.

Add `ContextTierService.get_scoped_metrics(project_names)` which uses
`ScopedBackendView` to filter fragment counts to the specified projects
while keeping hit/miss counters as global service-level cache metrics.
Update `context_inspect()` to call `get_scoped_metrics([project])`
instead of `get_metrics()`.

- `context simulate --focus` accepted focus URIs and passed them to the
`ContextRequest` model but never used them to filter the fragment list,
making the `--focus` flag a no-op.

Add focus URI filtering in `_simulate_context_assembly()` after
`get_scoped_view()` — filters `project_fragments` by matching each
fragment's `resource_id` against the supplied focus URIs.

Also fixes redaction false positives for hot_max_tokens and
summary_max_tokens keys, and Rich Console line-wrapping in test
output that caused JSON parse failures.

Includes 28 new Behave BDD scenarios for wiring coverage, updated
Robot Framework integration tests, and reference documentation.
