v1.0.0 - Initial LinuxVitals collection release

Published to Ansible Galaxy.

Added

• Initial release of LinuxVitals as an Ansible collection (sameeralam3127.linux_vitals), rebranded from the smart_os_health_check role-based project.
• Three composable roles: vitals_scan (read-only discovery and findings), vitals_heal (opt-in one-shot self-healing, disabled by default), and vitals_report (HTML/JSON dashboard, archive retention, Slack/email/generic-webhook notifications).
• playbooks/healthcheck.yml, runnable locally or via FQCN once installed (sameeralam3127.linux_vitals.healthcheck).
• Example inventory and group_vars under examples/.
• Baseline/postcheck maintenance workflow: playbooks/baseline.yml and playbooks/postcheck.yml snapshot each host's result under a shared linux_vitals_maintenance_id and automatically compute a before/after comparison (status change, RAM delta, kernel change, reboot-required change, new/resolved findings) for the postcheck run.
• Redesigned, self-contained HTML dashboard: executive KPI row with a health-score ring (pass-rate band: Excellent/Good/Fair/Poor), a searchable and sortable host table with expandable per-host detail rows, status/comparison filter chips, light/dark themes (OS-aware plus a manual toggle), a print/export stylesheet, and a per-host serial number field as a first piece of asset-level drilldown data.
• JSON report (schema 1.1) now includes maintenance phase/id, health-score and comparison rollups, and each host's asset_serial and comparison object.
• Full documentation suite under docs/ (installation, quickstart, configuration reference, variable reference, report guide, examples, troubleshooting, architecture) plus CONTRIBUTING.md.
• examples/playbooks/custom-thresholds.yml, a working example of overriding thresholds and enabling self-healing for a single run.
• Per-role README.md for vitals_scan, vitals_heal, and vitals_report (required by Ansible Galaxy's import validation -- the first publish attempt failed with "No role readme found").

Packaging

• Excluded tests/, pytest.ini, and requirements.yml from the published tarball via galaxy.yml's build_ignore -- they're dev/CI-only; galaxy.yml's own dependencies: block is what Galaxy uses to resolve community.general for installed-collection consumers.
• Verified end-to-end: built the tarball with ansible-galaxy collection build, installed it into an isolated collections path, and confirmed all three playbooks resolve and execute via FQCN (sameeralam3127.linux_vitals.healthcheck / .baseline / .postcheck) from that installed artifact, independent of the dev symlink.

Changed

• All smart_os_health_check_* variables, facts, templates, and default report filenames renamed to the linux_vitals_* / linux_vitals_report.* convention.
• Report output path and the .env secrets loader now resolve relative to inventory_dir instead of playbook_dir, so both local development and installed-collection usage read/write files in the operator's own project rather than inside the installed package.

Fixed

• Removed a byte-identical duplicate bootloader-detection task that ran the grub probe twice per host.
• Replaced a gawk-only bootloader parser with a portable POSIX sh implementation (bash/dash/system sh verified) and added numeric GRUB_DEFAULT index resolution.
• Stopped counting lastb's trailing btmp begins ... footer line as a failed login attempt.
• Fixed a Jinja filter-precedence bug where * 100 | round(1) rounded the literal 100 instead of the computed percentage.
• HTML-escaped journal/lastb-derived free text in the dashboard template.
• Added no_log: true to the tasks that load webhook/SMTP secrets from .env.

Security

• Removed real lab IP addresses previously committed in inventory/hosts.ini and inventory/multipass-10.ini; replaced with RFC 5737 documentation-range examples under examples/inventory/.
