Fossil: versionet e vjetra dhe historiku

- The "fossil ui /" command now works even for repositories that have non-ASCII filenames
- Add the fossil tree command.
- On case-insensitive filesystems, store files using the filesystem's preferred case rather than the case typed in by the user.
- Change the name "fossil cherry-pick" command to "fossil cherrypick", which is more familiar to Git users. Retain the legacy name for compatibility.
- Add new query parameters to the /timeline page: d2=, p2=, and dp2=.
- Add options to the fossil tag command that will list tag values.
- Add the -b|--brief option to the fossil status command.
- Add ability to upload unversioned files via the /uvlist page.
- Add history search to the /chat page.
- Add Unix socket support to the server command.
- On Windows, use the root certificates managed by the operating system (requires OpenSSL 3.2.0 or greater).
- Take into account zero-width and double-width unicode characters when formatting the command-line timeline.
- Update the built-in SQLite to version 3.47.0. Precompiled binaries are linked against OpenSSL 3.4.0.
- Numerous minor fixes and additions.

- Added the chat-timeline-user setting. If it is not an empty string, then any changes that would appear on the timeline are announced in the chat room.
- The /unsubscribe page now requests confirmation. Email notifications now contain only an "Unsubscribe" link, and not a link to subscription management.
- Added the "fossil branch lsh" subcommand to list the most recently modified branches.
- More elements of the /info page are now inside of an accordion.
- Replace the --dryrun flag with --dry-run in all commands which still used the former name, for consistency.
- Rebuilt the stock Dockerfile to create a "from scratch" Busybox based container image via an Alpine Linux intermediary
- Added a new document describing how to customize, use, and run that container.
- Added "by hour of day" report to the /reports page.
- Improved correctness, usability, and efficiency for the case when values in a TICKET's column tend to be long and volatile.
- Fixed a bug introduced in 2.17 that prevented clone --unversioned from completing the retrieval of UV files from the remote repo.
While fixing that, enabled UV tracing output with clone --unversioned --verbose, making it consonant with uv sync --verbose.
