feat: nvchecker autodetect expansion, -n stanza echo, --info/-i; release v1.2.5

Documents the Task 1-6 additions that shipped without doc updates: expanded
nvchecker source autodetection (gitlab, bitbucket, gitea, codeberg, pagure,
npm, gems, crates.io, cpan, hackage, packagist, cran, in addition to github
and pypi), the fenced stanza echo on --new/-n, and the --info/-i command
(category/program header plus paged README). Updates show_help, bash
completion, mkhint.1.md (rebuilds mkhint.1.gz), CLAUDE.md, and CHANGELOG.md.
Bumps MKHINT_VERSION to 1.2.5. No program logic changed; 224/224 tests still
pass.

+## [1.2.5] - 2026-07-09
+
+### Added
+- `--info` / `-i <pkg>`: shows a package's `category/program` path (green on a
+  TTY) followed by its README, paged with a sticky header (`less --header=1`)
+  only when the README is taller than the terminal. Missing package exits 2;
+  missing README prints `(no README)` and exits 0. Mutually exclusive with
+  `-V`/`-f`/`-n`.
+
+### Changed
+- `--new` / `-n` now prints the nvchecker stanza it manages on stdout, fenced,
+  whether it was just added or was already present, so the effect of the
+  autodetection is visible immediately instead of only living in the config
+  file.
+- Expanded nvchecker source autodetection (`_detect_nvchecker_source`) beyond
+  github and pypi to also recognize gitlab, bitbucket, gitea, codeberg, and
+  pagure owner/repo URLs, and the npm, gems, crates.io, cpan, hackage,
+  packagist, and cran registries. Registry sources parse the package name from
+  the URL where possible, falling back to `PRGNAM`.

 ## Key Behaviors
 
 - `--hintfile` update: backs up to `.bak`, replaces old version string globally via `sed`, re-downloads both URLs to recalculate MD5 checksums. Skips download if value is `UNSUPPORTED` or `UNTESTED`. After a successful update it dispatches slackrepo for the single package via `prompt_slackrepo`, which uses `pkg_in_repo` (glob `PACKAGES_DIR/*/<pkg>/<pkg>-*.txz`) to choose `slackrepo update` for a built package or `slackrepo build` for an absent one, both run through `run_slackrepo`.
-- `--new` with existing `.info`: copies `.info` as template, strips `PRGNAM`, `HOMEPAGE`, `MAINTAINER`, `EMAIL`, comments out `REQUIRES`, sets `ARCH="x86_64"`. Keeps `VERSION` from `.info`. If `-V` given, updates version string and recalculates checksums. Also appends an nvchecker `[section]` to the config, auto-detecting github/pypi source or providing a commented stub.

If `-V` given, updates version string and recalculates checksums. Also appends an nvchecker `[section]` to the config via `add_nvchecker_section`.
+- `add_nvchecker_section` autodetection: `_detect_nvchecker_source` recognizes github, gitlab, bitbucket, gitea, codeberg, and pagure owner/repo URLs plus the pypi, npm, gems, crates.io (`cratesio`), cpan, hackage, packagist, and cran registries, else leaves a commented stub. Github gets `use_latest_release = true` with commented `use_max_tag`/`prefix = "v"` fallbacks; the other forges get `use_max_tag = true` plus a commented `# prefix = "v"`; registries use the package name parsed from the URL via `_registry_name_from_url`, falling back to `PRGNAM` when no host-specific pattern matches. Either way, the managed stanza (freshly added or already present) is echoed fenced on stdout via `_extract_nvchecker_section`.
 - `--new` when hint already exists: backs up old, creates empty skeleton.
 - `--hintfile` with no `-V`: queries nvchecker for latest version, shows current vs. latest, prompts to accept/override/decline. After accepting, runs `nvtake` to sync nvchecker's keyfile.
 - `--list` / `-l`: lists hints with `HintVer`/`SBOVer` plus a `DelReq` column (before `Created`) showing `✓` when the hint has a populated `DELREQUIRES` (detected via `grep '^DELREQUIRES="..*"'`, padded with `_pad_glyph` so the multibyte glyph stays aligned). Hints with no `VERSION` are skipped (and excluded from the total). Version columns are 22 wide to fit long version strings. Coloring: rows where the two versions are byte-equal get the whole row yellow (and populate `MATCHED_PKGS` for `-R`); when they differ, `sort -V` picks the newer side and only that version cell is green (version strings are pre-padded to 22 before the color wrap so the escape bytes don't break alignment); an absent/empty `SBOVer` leaves the row plain. Color only on a TTY (or `MKHINT_FORCE_COLOR`); plain when piped. Legend `(yellow row = versions match; green = newer side)` prints when any row matched. With package names (`-l foo bar`), the table is skipped and each named hint is shown side by side with its `.info` via `_show_hint_diff` (shared with `--review`); missing hint → exit 2.

 - `--delete` / `-d`: removes hint file and `.bak` if present. Accepts multiple package names. Exits 2 on first missing file.
+- `--info` / `-i <pkg>`: globs `REPO_DIR/*/pkg/` for the category, prints the green `category/program` header then the README, paged with sticky header (`less --header=1`) only when the README is taller than the terminal (inline when it fits or when piped), missing package exits 2, missing README prints `(no README)` and exits 0. Mutually exclusive with `-V`/`-f`/`-n`. Handler `show_info`.
 - Downloads go to `/tmp/mkhint/download` (single shared temp file, deleted after md5 calculation).
 - Multiline `DOWNLOAD`/`DOWNLOAD_x86_64`: parsed via `parse_multiline_var` (awk). First URL always re-downloaded. Continuation URLs (2+) prompt user interactively — changed URLs re-downloaded, unchanged URLs keep existing md5. Written back via `perl -i` with `\` continuation format preserved. Shared logic in `update_checksums` → `_process_download_var`.
