feat: support minimizing (hiding) comments

[mshick]

Summary

Adds the ability to minimize (hide/collapse) comments instead of only creating, updating, or deleting them — addressing #197.

Hiding a comment isn't in the GitHub REST API; it's the minimizeComment GraphQL mutation (keyed by the comment's node_id, with a required classifier). This PR wires that in behind three new inputs and a new output, for both the PR/issue and commit-comment paths.

New inputs

Input	Values	Default	Effect
create-minimized	true | false	false	Minimize a comment immediately after it is created (not on later updates). A refresh-message-position recreate stays minimized.
delete-method	delete | minimize	delete	When delete-on-status matches, delete (current behavior) or minimize the existing comment.
minimize-reason	outdated | resolved | off-topic | duplicate | spam | abuse	outdated	Classifier shown in GitHub's UI for any minimize action.

New output

• comment-minimized — "true" when a comment was minimized.

Notes / decisions

• Proxy: minimize needs write permissions the proxy (fork-PR) path doesn't grant, so combining proxy-url with create-minimized or delete-method: minimize fails fast with a clear error. The guard lives in the PR proxy branch, so comment-target: commit (which ignores proxy-url) can still minimize.
• Scope: no un-minimize/toggle — create-minimized applies only at creation; nothing re-asserts or reverses view state on later runs (YAGNI).
• minimize-reason is parsed case-insensitively and normalized to the GraphQL ReportedContentClassifiers enum (off-topic → OFF_TOPIC); invalid values throw at config-parse time.

Tests

Adds an MSW handler for the GraphQL endpoint and covers: create-minimized → mutation fired with the new node ID; plain updates do not minimize; delete-method: minimize minimizes instead of deleting; classifier default + override mapping; proxy-url + minimize → config error; commit-comment minimize. Full suite: 83 passing.

Design docs

Spec and implementation plan included under docs/superpowers/ for reviewer context (drop the last commit if you'd rather not keep them in-tree).

Pull request overview

This PR adds support for minimizing (collapsing/hiding) comments via GitHub’s minimizeComment GraphQL mutation, extending the action beyond create/update/delete to also support “hide on create” and “hide instead of delete-on-status”.

Changes:

• Adds new inputs (create-minimized, delete-method, minimize-reason) and a new output (comment-minimized) to control minimize behavior.
• Threads node_id through existing-comment lookups and adapters so comments can be minimized via GraphQL.
• Implements and tests minimize behavior for both PR/issue comments and commit comments, with a proxy-url fail-fast guard.
