docs(examples): rename issue resolver shared helper and remove grandf…

[rishugudigar]

…athered parity exception

Description

his PR cleans up the dev_tools/issue_resolver example/docs pairing by standardizing the shared GitHub-fetch helper under examples/issue_resolver_common.py and updating the provider examples to use it consistently. It also aligns the docs and registry expectations so the helper is treated as a support module rather than a runnable example, which keeps the example inventory and documentation story in sync.
Fixes #233

Type of Change

• New Skill — new registry bundle under skills/
• Skill Upgrade — changes to an existing skill under skills/
• Bug Fix — incorrect runtime or framework behavior
• Documentation — docs, README, CONTRIBUTING only
• Framework Feature — skillware/core/ loader, env, adapters
• CLI — skillware/cli.py, docs/usage/cli.md
• Examples — examples/*.py, agent loops, examples/README.md
• Packaging — PyPI wheel, pyproject.toml, MANIFEST.in
• RFC / meta — templates, labels, CI, or large design doc

Thanks @rishugudigar, this matches the scope nicely.

Before re-requesting review:

• Changelog has a conflict, should be easy fix with rebase
• Fill in the PR description (2–3 sentences on what changed and why), looks cut to me at start
• Tick Examples in the type checklist since examples/*.py changed

Once these are clean, this is good to merge <3
