ci: weekly SemVer releases with generated notes; freeze CHANGELOG.md at 1.7.4 (#800 )

* ci: publish a weekly SemVer release with GitHub-generated notes Every Monday at 06:00 UTC the workflow tags master and publishes a GitHub Release whose notes list the merged PR titles. tools/next_version.py picks the version from the commits since the last release: type!: or a BREAKING CHANGE footer is major, feat is minor, anything else is patch. A manual run can override it. Weeks without commits are skipped, a master commit whose CI did not pass is never released, and forks never run it. * docs: point contributors and forks at weekly GitHub Releases PR titles are now the release notes and their type sets the version, so CONTRIBUTING and the PR template say so. README and SETUP describe releases as weekly checkpoints that passed CI instead of pointing at CHANGELOG.md. * chore(changelog): freeze at 1.7.4 and fail PRs that still edit it Rolls [Unreleased] into [1.7.4] and rewrites the intro to point at GitHub Releases. The structure test becomes a content pin: stale PRs carry entries that git would merge cleanly into the frozen section, so any edit now fails CI with a pointer to the PR title. * fix(release): address review findings on the weekly release Write access moves to the job; the override rejects existing or older versions; next_version.py reports a missing tag instead of a traceback and drops the unused rev argument; tests pin the fork guard and SHA-pinned checkout. The frozen changelog drops the date written ahead of the release, describes its guard accurately, and the guard skips on forks. * chore(changelog): re-pin the frozen hash after rebasing onto master * ci(release): compute the version with commitizen via setup-uv instead of an in-repo script A week of only docs, chore or ci commits now ships nothing on its own, matching commitizen's conventional-commit bump rules; fix, refactor and perf bump patch.
fix(guards): refuse a .npmrc beside a portal manifest, like bunfig.toml

  rendered. Default `markdown`, which keeps the posting's headings and requirement
  lists intact. `json` output only.

+**Query operators.** `-q` understands two operators; the CLI passes the text through
+unchanged and the API parses it:
+
+- `OR` between alternatives returns jobs matching **any** of them, e.g.
+  `-q "golang OR rust"`. Uppercase only: a lowercase `or` is an ordinary search
+  word. Plain space-separated words are **not** a union (`-q "golang rust"` returns
+  fewer jobs than `-q golang` alone), so use `OR` for synonyms and alternative stacks
+  instead of running one search per keyword. At most 5 alternatives; a 6th is
+  rejected with an error. An `OR` inside double quotes is literal text.
+- A leading `title:` restricts that alternative to the job **title**, e.g.
+  `-q "title:staff engineer"` skips postings that merely mention the words in their
+  description. It applies per alternative, so repeat it on each one:
+  `-q "title:staff engineer OR title:principal engineer"`. It only counts at the start
+  of an alternative; `title:` in the middle is searched as text. Quotes work inside it:
+  `-q 'title:"staff engineer"'` matches the phrase.
+
+Facet flags, `--jobage`, `--page` and `--limit` apply to the combined result: every
+alternative is filtered the same way, and a job matching several alternatives
+appears once.
+
 **Search results already carry the full description.** This skill queries freehire's
 agent search endpoint, which replaces the index's truncated preview with each
 posting's complete text, so a search of 20 roles is 1 request rather than 1 + 20.
 Do **not** loop `detail` over search hits to read their descriptions — reach for
 `detail` only to look one posting up by slug (e.g. from the tracker, or a posting
 already closed and therefore absent from search). Full descriptions are verbose:
-keep `--limit` modest, and pre-filter on title/company before reading bodies.
+keep `--limit` modest, and pre-filter on title/company before reading bodies -
+or pass `--no-description` for a cheap discovery pass that keeps every other
+field and drops the bodies entirely (fetch a shortlisted job's body with
+`detail`, or re-run the search without the flag).

 Facet filters (values come from freehire's controlled vocabularies; comma-separate for OR within a facet):
- `--region <codes>` — macro-region, e.g. `global`, `eu`, `us`, `apac`, `latam`, `cis`. `--region eu,us`. Use `none` to match jobs whose region could **not** be resolved (see "Partial data" below).
+- `--region <codes>` - macro-region: `global`, `eu`, `uk`, `north_america`, `latam`, `apac`, `mena`, `africa`, `cis`. `--region eu,uk`. `eu` does not include the UK; add `uk` for Europe as a whole. For a single country use `--country` instead - `us` is a country code, not a region, and `--region us` matches nothing. `--region`, `--country` and `--city` form one OR-group, so `--country us` alone scopes to the US. Use `none` to match jobs whose region could **not** be resolved (see "Partial data" below).
 - `--country <codes>` — ISO-3166 alpha-2, e.g. `--country DE,GB`
 - `--city <names>` — city name(s), e.g. `--city Berlin`
 - `--seniority <levels>` — `junior`, `middle`, `senior`, `staff`, `principal`, `lead`, …
 - `--category <cats>` — `backend`, `frontend`, `fullstack`, `devops`, `ml_ai`, `qa`, …
 - `--skill <names>` — canonical skill(s), e.g. `--skill go,kubernetes`
 - `--company <slug>` — company slug (from a result's `company_slug`)
- `--remote <mode>` — `remote` | `hybrid` | `onsite` (`work_mode` facet)
+- `--remote <mode>` — `remote` | `hybrid` | `onsite` (`work_mode` facet). A bare `--remote` means `remote`. Comma-separate for OR (`remote,hybrid`; `on-site` normalises to `onsite`). An unknown item exits 1 with `BAD_ARG`.

+example under `jobsearch.result_app.storeData.searchResponse`:

-```html
-<div class="jix_pagination_total"><strong>1</strong> til <strong>20</strong> af <strong>18.903</strong> resultater.</div>

-| `title` | `h4 > a` text content |
-| `url` | `h4 > a[href]` |
-| `company` | `.jix-toolbar-top__company a` text |
-| `companyUrl` | `.jix-toolbar-top__company a[href]` |
-| `location` | `span.jix_robotjob--area` text |
-| `date` | `time[datetime]` attribute value |
-| `description` | `p` text content (first `<p>` in card) |
-
-Two card types exist: `div.PaidJob` (sponsored) and `div.jix_robotjob` (aggregated). Both use the same selector pattern.
+The active search path maps these fields directly; it does not parse job-card
+HTML or `hitcount_html`. `extractStash` and `parseSearchPage` in `src/helpers.ts`
+implement this path. The legacy `parseJobCards` helper is not used by `search`.

+on 2026-07-14 and published in [upstream PR #153](https://github.com/ai-job-search-dev/ai-job-search/pull/153).
+That PR was closed because it was accidentally submitted to upstream instead of
+the author's personalized fork; it was not merged.
+
+Source: `.agents/skills/linkedin-search/cli/test/__fixtures__/detail-orbis.html`
+at commit `5bc3afb94d19b670ecf09287c20d0c95e5d13ba0`.
+Original SHA-256: `2125a346c22f471e3db08cd3890d0569b194703fe5f49b831cdde257e4aa4a59`.
+
+Only the title, closed banner, description markup and criteria list are retained.
+Their bytes are unmodified; recruiter cards, images, tracking links and unrelated
+page sections are omitted. The description includes real adjacent paragraphs,
+empty paragraphs and list items, rather than hand-written parser examples.
+
+The CLI regression serves this saved response over loopback and redirects only
+the exact expected guest endpoint to it in a child process. It makes no LinkedIn
+requests and does not regenerate the fixture during tests.

+# Offline search cards
+
+`search-cards.json` stores the HTML string for the first two verbatim `<li>` cards from a real
+LinkedIn guest search response captured by **portapulito** through the CLI's
+`htmlFetch` on 2026-07-14 and published in [PR #153](https://github.com/ai-job-search-dev/ai-job-search/pull/153).
+That PR was closed as an accidental personalized-fork submission, not merged.
+
+Source: `.agents/skills/linkedin-search/cli/test/__fixtures__/search-list.html`
+at commit `5bc3afb94d19b670ecf09287c20d0c95e5d13ba0`.
+Original response SHA-256: `ff5fb9009f26c8f602b1ac4b018f471e76784300723b22db64d9d19c2b7f557c`.
+Two-card excerpt SHA-256: `1ab95e6ccb38b50d922e4d714ff95bb58219c012489a3a94aca5e0adb7b552fb`.
+
+The JSON string encoding preserves the original HTML whitespace without adding
+trailing whitespace to source lines. The excerpt hash above is of the decoded HTML.
+
+The valid-flag controls serve these saved cards over loopback HTTP. Their child
+CLI preload accepts only the expected search endpoint and redirects that request
+to loopback. Tests assert the actual URL parameters, successful output, IDs and
+client-side result limits. No fixture regeneration or portal request occurs.
+This isolates these controls; it is not an OS-level egress policy for the entire CI.
