fix(repo): pythinker-cli rename sweep + feat(installer): hosted Windows uninstaller (#252)

* fix(repo): update all repository URLs after rename to pythinker-cli

The GitHub repository was renamed from Pythoughts-labs/pythinker-code to
Pythoughts-labs/pythinker-cli, and the old name's redirect no longer applies.
Update every repo-slug constant and URL: install scripts (all copies), the
in-app updater, the default feedback repo, the docs-pages repository guard,
winget/homebrew/scoop workflow links, README, docs, and matching tests.

* feat(installer): add hosted Windows uninstaller one-liner

Add scripts/uninstall.ps1, served at https://pythinker.com/uninstall.ps1
mirroring the installer bootstrap (irm ... | iex). It runs the registered
Inno uninstaller silently, sweeps validated install dirs, PATH entries
(user + system, kind-preserved), Start Menu shortcuts, uninstall registry
keys (32/64-bit views), and stale installer temp dirs, then verifies the
final machine state with fail-closed semantics and a structured summary.

Safety: registry-provided paths are never deleted or executed without
validation (leaf named Pythinker plus on-disk evidence, no reparse-point
component, trusted unins<N>.exe only); processes are stopped per-PID only
when rooted in a validated install dir with StartTime/Path revalidation;
the script never self-elevates and never calls exit, so piping through
iex cannot close the host session. User data is kept unless
PYTHINKER_PURGE_DATA=1.

Ship byte-identical copies in docs/public and web/public with matching
_headers cache entries, document the one-liner in the README Windows
section and the getting-started guide, and cover sync/parsing/README
assertions in test_installation_docs.py.

* refactor(installer): harden Windows uninstaller deletion and execution policy

Replace the removal engine with a snapshot-based design
(Get-SafeTreeSnapshot + Remove-SafeSnapshotNow): complete-or-fail-closed
tree inspection, per-entry non-recursive deletes that never rely on
PS 5.1 reparse traversal, and re-inspection before reboot scheduling.

Tighten policy: recursive sweeps run only against known install dirs
(LOCALAPPDATA + ProgramFiles x2); registry-selected custom installs are
never swept or executed automatically - they get exact PATH-token removal
and a manual-action report. Inno uninstallers execute only non-elevated,
user-scope, from a known dir, as a trusted unins<N>.exe; no registry
selected binary ever runs with an elevated token.

Also: canonicalize all registry-provided paths (reject roots, UNC/device,
drive-relative, reparse components), re-read PATH under the writable
handle before SetValue, broadcast WM_SETTINGCHANGE only on actual change,
prove installer-temp ownership via AppId marker or verified SHA-256,
handle 32-bit registry views natively, dedupe warnings, and bound the
uninstaller run with a 10-minute timeout.

Uses DirectorySeparatorChar in path-prefix checks (identical to '\' on
Windows; keeps the logic testable cross-platform).

* fix(installer): replace -ine operator flagged by the typos workflow

Use [string]::Equals(..., OrdinalIgnoreCase) for the Pythinker leaf-name
check; identical semantics, and the repo has no typos config to suppress
the PowerShell -ine operator being flagged as a misspelling.

* fix(repo): address CodeRabbit review findings on the rename sweep

- issue template: make the discussions link label match its pythinker-cli target
- README: fix 'cd pythinker-code' after cloning pythinker-cli.git
- feedback: migrate saved Pythoughts-labs/pythinker-code repo values (the
  pre-rename bundled default) to pythinker-cli, with a regression test
- help skill: point documentation base/llms.txt/page URLs at the canonical
  pythinker-cli GitHub Pages path instead of relying on the rename redirect
- tests: report a missing pwsh as pytest.skip instead of a silent pass

* docs(skills): add language tag to llms.txt URL fence (MD040)
