Fix ISSUE_PATTERN to handle Slack URL formats

[atm-snag2]

What

Closes #58

Why

How

Handle domain-without-protocol (github.com/owner/repo/pull/123) via an alternative pattern [^/]+\.[^/]+/ alongside the existing https?://[^/]+/.
This pattern only matches strings containing a dot (.), so it won't consume owner/ in owner/repo#123 as a domain (GitHub usernames cannot contain dots).

Non Goal

• Handling Slack's <url|text> pipe format is out of scope — the adapter layer parses it and passes only the display text to the handler

Refs

• Slack URL formatting

ISSUE_PATTERN unit tests

Format	Input	repo	number
owner/repo#number	alice/test#123	alice/test	123
Full URL (/issues/)	https://github.com/alice/test/issues/123	alice/test	123
Full URL (/pull/)	https://github.com/alice/test/pull/123	alice/test	123
Protocol-stripped (Slack)	github.com/alice/test/pull/123	alice/test	123
Angle-bracketed	<https://github.com/alice/test/pull/123>	alice/test	123

#close_issue integration tests

• @ruboty close issue alice/test#1 — existing format ✅
• @ruboty close https://github.com/alice/test/issues/1 — full URL ✅
• @ruboty close github.com/alice/test/issues/1 — Slack display text ✅
• @ruboty close <https://github.com/alice/test/issues/1> — angle brackets ✅

Code Review

This pull request updates the ISSUE_PATTERN regular expression in lib/ruboty/handlers/github.rb to support protocol-stripped URLs and angle-bracketed URLs, along with adding comprehensive test coverage in spec/ruboty/handlers/github_spec.rb. Feedback suggests replacing the greedy wildcard (?<repo>.+) with (?<repo>[^/]+/[^/]+) to prevent incorrect domain parsing when owner names contain dots and to avoid potential backtracking performance issues.

Code Review

This pull request updates the ISSUE_PATTERN regular expression in the GitHub handler to support protocol-stripped and angle-bracketed URLs, and adds corresponding unit and integration tests. The review feedback highlights that Slack automatically formats protocol-stripped URLs with a pipe and display text (e.g., <url|text>), which will cause the pattern matching to fail due to the \z anchor in commands. The reviewer suggests updating the regex to handle this Slack link format and adding corresponding test cases to verify both the pattern matching and the #close_issue action.
