Add getdnote.com feature

[Copilot]

Adds a devcontainer feature for dnote — a single-binary, SQLite-backed command-line notebook.

Changes

• src/getdnote.com/ — new feature using the gh release install method
• src/getdnote.com/install.sh — customises the standard github_list_releases / github_get_tag_for_version helpers to handle dnote's non-standard cli-v{version} release tag prefix (assets follow the pattern dnote_{version}_linux_{arch}.tar.gz)
• test/getdnote.com/test.sh — verifies installation via dnote version
• README.md — adds entry alphabetically between fzf and github.com-cli

Fixed in f036beb. The dnote release archive stores the binary as ./dnote (with a leading ./), but the script was looking for dnote (without it), causing tar: dnote: Not found in archive. Updated binaryPathInArchive to ./dnote, which also makes the stripComponents calculation yield 1 (strips the ./ prefix), so the binary is correctly extracted to /usr/local/bin/dnote.
