Adds --skip-ssl-verify flag (GITHUB_SKIP_SSL_VERIFY env var) that disables
TLS certificate verification for both REST and GraphQL clients. Intended for
private GitHub Enterprise instances with self-signed or missing certificates.

Covers: default transport passthrough, InsecureSkipVerify flag set,
successful connection to self-signed TLS server, and TLS rejection
when skip is disabled.

Feature/skip ssl verify

Adds ParseGitHubURL and ApplyURLParam to pkg/github/url_parse.go.

ParseGitHubURL parses any GitHub resource URL (repo, issue, PR, file blob)
across github.com and self-hosted GHE instances, extracting owner, repo,
number, ref, and path.

ApplyURLParam applies parsed URL fields into a tool's args map before
parameter extraction, with explicitly set params taking precedence.
29 tests covering valid URLs, error cases, and precedence rules.

feat: add GitHub URL parsing utility

Adds a new get_repository tool that fetches metadata for a single GitHub
repository by owner/repo or by URL. Returns a richer field set than
MinimalRepository: visibility, clone_url, ssh_url, is_template, pushed_at,
and named is_fork/is_archived fields.

Integrates with ApplyURLParam so agents can pass a full repo URL instead
of discrete owner/repo params. 8 tests covering happy path, URL parsing,
precedence, missing params, and API errors.

Feature/get repository

Adds optional client-side filtering to IssueRead and PullRequestRead
to reduce token usage when AI agents only need a subset of comments.

New filter params on issue_read (applies to get_comments):
  - author: filter by comment author login (case-insensitive)
  - bodyContains: filter by substring or regex in comment body

New filter params on pull_request_read:
  - author: filter by author login (get_comments + get_review_comments)
  - bodyContains: filter by body text (get_comments + get_review_comments)
  - filePath: glob pattern for review thread file path (get_review_comments)
  - reviewer: filter by reviewer login (get_reviews)
  - state: filter by review state (get_reviews)

Adds createdAfter/createdBefore params to comment and review comment
filters, and submittedAfter/submittedBefore to review filters. All
dates are RFC3339 strings; invalid or unparseable dates are excluded.

- issue_read: createdAfter, createdBefore (get_comments)
- pull_request_read: createdAfter, createdBefore (get_comments, get_review_comments)
- pull_request_read: submittedAfter, submittedBefore (get_reviews)

12 new tests added covering after, before, combined, and invalid date edge cases.
