feat: release stamping slim — wheels+tags only, no daily bump commits (R3-core)

[Jammy2211]

⛔ Merge gate

Merge PyAutoLabs/PyAutoConf#119 (compatibility-floor version check) first. The release that stops writing workspace version pins must also ship floor semantics, so the last-stamped workspace_version values behave as floors, not exact-match tripwires. Both are pending-release; one release window carries both.

Overview

R3-core of the version-pinning design review (#118; task issue #120). Releases become wheels + tags only: no more daily "Update version to X" commits to five library mains, no more "pin workspace version" / README-stamp commits to every workspace main — the stale-CI/email noise engine behind the June/July accidental-release cascade. Also removes the scheduled run_number version fallback that produced the 2026.6.25.641 → 2026.7.6.649 accidental series.

Issue: #120 · Design review: #118

Changes (.github/workflows/release.yml, docs/internals.md)

1. version_number: scheduled runs default the minor to 1 (<date>.1), never github.run_number, in both live and rehearsal compositions. Rehearsal uniqueness still comes from the .devN segment. A same-day manual dispatch after a scheduled live release must pick its own minor_version (twine rejects duplicates loudly — stated in a comment).
2. release job: the sed version stamp still runs (wheels carry the version) but is no longer committed back; branch git push dropped, git push --tags kept — tags remain the release anchor for Colab URLs and workspace pairing.
3. release_workspaces: "Update version in README" and "Write workspace version" (version.txt + general.yaml) steps removed — obsolete under the floor check. Notebook regen, Colab bumps, API baseline, and workspace tags untouched (their cadence under daily live releases is Q2 on research: version-pinning design review — exact pins vs daily release #118, decided separately).
4. docs/internals.md pure-executor and version-skew paragraphs updated to match.

Test Results

• tests/: 71 passed. Workflow YAML parses clean.
• Grepped for consumers of the removed steps: none in autobuild/; PyAutoHeart's version_skew check reads the now-frozen artifacts and stays functional-but-inert during the transition — its floor-vs-tag rework is a filed follow-up.

Ship gate

Supervised --auto run; maintainer sign-off + Heart YELLOW acknowledgement (same 6-reason set as PyAutoConf#119's gate) given in-session on 2026-07-08 ("continue --auto" following the surfaced sign-off summary).
