Add community guidance and review support for Business Central agents (#137)
* feat(community/agents): add AL agent quality guidance

- add 20 agent knowledge rules with good and bad AL samples
- clarify setup dialog shape, temporary persistence, permissions, profiles, instructions, capability registration, and interface wiring
- add the community-owned AL agents review skill
- make review fixture discovery layer-aware with custom, community, and Microsoft precedence
- document layer-aware evaluation behavior

* fix(community/agents): align setup and permission samples

- mark agent setup pages as non-extensible where required
- narrow the agent profile by hiding an unrelated sales-order field
- define a dedicated read-only permission set for the sales review agent
- assign AL-defined permission sets with system scope and the owning app ID
- clarify the permission scope guidance for default access controls

* Address agent review feedback

# AL agents review
Reviews AL source changes against the `agents` knowledge domain in BCQuality and emits a findings report. This is a leaf action skill: it invokes no sub-skills. It is not one of the skills composed by `al-code-review`; Entry discovers and dispatches it as a top-level peer, so it produces an independent findings report.
Agent findings apply to AL files that implement or invoke Agent SDK surfaces, including agent interfaces, setup, creation, task execution, capability registration, profiles, access controls, instructions, and session-bound subscribers. Return `not-applicable` when the diff contains no AL changes or no Agent SDK implementation or usage.
An orchestrator invokes this skill with either a `pr-diff` or a `file-path`. The skill produces one JSON document conforming to the DO output contract.
## Source
Read the root `knowledge-index.json` generated by Entry and select entries whose `domain` is `agents` across every enabled layer. Use index metadata for candidate selection and open an article body only after it enters the worklist.
## Relevance
Apply READ's frontmatter matching semantics to the target BC version, AL technology, countries, and application areas. If a dimension is unknown, retain conditionally applicable guidance only when configuration permits it; cap resulting confidence at `medium` and name the unknown dimension in the finding message.
## Worklist
Match changed objects, procedures, interfaces, and tokens against article keywords, titles, descriptions, and paths. Give particular weight to:
- Implementations of `IAgentFactory`, `IAgentMetadata`, and `IAgentTaskExecution`.
- Agent setup tables and `ConfigurationDialog` pages using `Agent Setup`, `Agent Setup Buffer`, or `Agent Setup Part`.
- Agent creation, upgrade, capability registration, profile configuration, access controls, and subscriber binding.
- Instruction construction, `SecretText`, documented instruction keywords, task messages, trusted input, warnings, errors, and review behavior.
- Public APIs invoked by agent tasks across app boundaries.
Use these targeted rules to avoid broad token-only matches:
- Worklist setup-page shape guidance when the page returned by agent metadata is not a `ConfigurationDialog` or omits `Agent Setup Part`.
- Worklist temporary-source guidance when setup writes occur before a non-Cancel close path or a setup page is not temporary.
- Worklist permission guidance when default access controls are broad or when code assumes an agent can exceed the assigning user's permissions.
- Worklist instruction guidance only for text used as agent instructions; do not flag unrelated prompts, labels, or user-facing help.
- Worklist session-binding guidance only when subscribers are bound outside an agent session or left bound after execution.
After selection, resolve conflicting guidance using READ's layer precedence. Record displaced candidates in `suppressed` with `reason: "layer-precedence"`; record disabled-layer candidates with `reason: "configuration"`.
An empty worklist caused by absent applicable knowledge produces `no-knowledge`. An empty worklist caused by no match produces `completed` with no findings.
## Action
Evaluate each worklisted article's `## Best Practice` and `## Anti Pattern` against the changed code:
- Emit `major` for a clear anti-pattern and `minor` for a concrete best-practice contradiction.
- Use `blocker` only when the article identifies a violated platform guarantee.
- Do not emit a finding from applicability alone.
- Set confidence to `high` for unambiguous syntax or identifier evidence, `medium` for heuristic or conditionally applicable evidence, and `low` only for an explicit advisory.
Agent-originated findings without a matching article must follow the DO contract: prefix the ID with `agent:`, use `references: []`, cap severity at `minor` and confidence at `medium`, and emit only concrete defects within the agents domain.
Provide `suggested-code` when the repair is small, local, and unambiguous. Otherwise, when a mechanical-looking repair depends on missing context or has multiple valid forms, set `suggested-code-omission-reason`.
Use the standard DO outcomes: `completed`, `no-knowledge`, `not-applicable`, `partial`, or `failed`.
## Output
Return only one JSON document conforming to the DO output contract. Every finding emitted by this skill MUST set `findings[].domain` to `"Agents"`. Knowledge-backed finding IDs and references MUST use the exact repository-relative article path from the knowledge index.
