chore(aim): adopt the standard AGENTS.md template

[tablackburn]

Summary

Moves this repository onto AIM's standard AGENTS.md template at v0.11.0, joining the five
sibling repositories (ReScenePS, PlexAutomationToolkit, YouTubeMusicPS, SrrDBAutomationToolkit,
ScheduledTasksManager) that already run it. Hand-written content is relocated, not deleted.

Why

The hand-written AGENTS.md had no Template Version stamp and no Instruction Applicability
Matrix. When the agent skills were vendored into .agents/skills/ in #52, the Skill Dependencies
section landed but had nowhere to route from: it says the skills "are routed from the Instruction
Applicability Matrix above", and there was no matrix above it. Agents that do not natively scan
.agents/skills/ therefore never saw the psake and PowerShellBuild skills.

What changed

AGENTS.md is now AIM's AGENTS.template.md at v0.11.0, adapted the way the siblings did it:

• the THIS IS THE TEMPLATE FILE comment block is deleted
• Template Version: 0.11.0, Last sync: 2026-08-19
• the skills matrix row and the Skill Dependencies section are copied byte-for-byte from
  ScheduledTasksManager and ReScenePS; the file is now identical to ReScenePS/AGENTS.md
  apart from the sync date

instructions/repository-specific.instructions.md absorbs the bespoke content. That file is
never synced from upstream, so it is the correct home for it:

Bespoke section	Where it went
Repository Overview	## Project Overview - appended as the conventions list
Key Files	new ### Key Files table under Module Structure (plus build.depend.psd1)
Common Tasks: build	already covered by ## Build Process; not duplicated
Common Tasks: test	already covered by ### Running Tests; not duplicated
Common Tasks: new fn	new ## Adding a New Function
Code Style	new ## Code Style (the prefix rule was already in Naming Conventions)
Testing Requirements	merged into ### Pester Tests; only the Pester version line was new
Instructions Directory	superseded by the applicability matrix in AGENTS.md

Staleness fix

Both files claimed "Testing (Pester 5.x)" and "Use Pester 5.x syntax". That is stale:
build.depend.psd1 pins Pester = @{ Version = 'latest' }, and the custom UnitTest task in
build.psake.ps1 exists precisely because of the Pester 6 rollout (its comments reference Pester
6.0.1 and 6.1.0 breaking CI). The text now says Pester 6 and names build.depend.psd1 as the
source of truth rather than restating a version that will drift again.

Unchanged

• CLAUDE.md still starts with @AGENTS.md, bridging the routing into Claude Code
• .agents/skills/ is untouched
• the {{ModuleName}}, {{Prefix}}, and {{Description}} placeholders are preserved, so
  Initialize-Template.ps1 still substitutes them on init

📝 Walkthrough

Walkthrough

The PR replaces the repository agent guidance, adds PowerShell module conventions and development requirements, expands Pester 6 testing guidance, and pins the Pester dependency to latest.

Changes

Repository guidance

Layer / File(s)	Summary
Agent workflow and instruction routing AGENTS.md	Adds template metadata, mandatory workflow steps, an applicability matrix, instruction references, and quick-reference practices.
PowerShell practices and Pester 6 guidance instructions/repository-specific.instructions.md	Documents module structure, key files, function requirements, Pester 6 usage, and the latest Pester dependency.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk:🟡 Moderate · up to 578eb

The new instruction-routing matrix may fail to direct agents to repository guidance because its file paths omit the instructions/ directory, and the updated Pester guidance conflicts with the dependency policy. These bounded issues should be corrected or explicitly accepted before merging.

Pull request overview

Adopts AIM’s standard AGENTS.md template (v0.11.0) for this repository and migrates the previously hand-written, repository-specific guidance into instructions/repository-specific.instructions.md, aligning this repo with the rest of the module fleet.

Changes:

• Replaced the custom AGENTS.md content with the standard AIM template, including the applicability matrix and skill routing.
• Moved bespoke repository guidance into instructions/repository-specific.instructions.md and expanded it with “Key Files”, “Code Style”, and “Adding a New Function”.
• Updated testing guidance to reflect the current Pester rollout and dependency pinning approach.

File	Description
AGENTS.md	Switched to the AIM standard agent-instructions template with an applicability matrix and skill routing.
instructions/repository-specific.instructions.md	Consolidated repository-specific guidance (structure, key files, style, testing, and contribution workflow).

instructions/repository-specific.instructions.md:87

• This section says “Use Pester 6 syntax”, but the build pins Pester to Version = 'latest', so the installed major version can change over time. Consider wording this as “Pester syntax” and defer the exact version to build.depend.psd1 to avoid this becoming stale again.

- Use Pester 6 syntax (`BeforeAll`, `BeforeDiscovery`, and so on). `build.depend.psd1` pins
Pester to `latest`, so the build floats onto the newest released major version; the `UnitTest`
task in `build.psake.ps1` reads that same value so the installed and imported versions agree

instructions/repository-specific.instructions.md:117

• The dependency list calls out “Pester 6”, but build.depend.psd1 sets Pester = @{ Version = 'latest' } (so the major version can change). To prevent future drift, avoid hardcoding the major version here.

- PowerShell 5.1 or higher (PowerShell 7+ recommended)
- No external module dependencies for runtime
- Pester 6 (for testing; `build.depend.psd1` pins `Version = 'latest'`)
- psake (for build automation)

- Around line 16-22: Update the testing convention statement near “Pester 6” to
match the repository’s dependency policy: either describe the supported
compatibility policy when Version = 'latest' is intentional, or constrain
dependency and build selection to Pester major version 6 when that is the
contract. Keep the module fleet conventions unchanged.
