Keeps the implemented-module README over main's placeholder, keeps PSModuleTest.Tests.ps1 removed (replaced by Confluence.Tests.ps1), applies the Pester 6.x requirement from #16 to Confluence.Tests.ps1, and picks up the Process-PSModule workflow bump to v5.5.7.

Confluence is now a working PowerShell module: connect to an Atlassian
Confluence Cloud site once and manage pages, spaces, blog posts,
folders, comments, labels, content properties, attachments, and
restrictions as first-class PowerShell commands. This first version
ports the generalized Confluence REST v2 client into the PSModule source
layout and wires it to the Process-PSModule build.

## New: 41 Confluence commands

Grouped by resource area:

- **Auth** — `Connect-Confluence`, `Disconnect-Confluence`,
`Get-ConfluenceContext`
- **Config** — `Get-ConfluenceConfig`, `Set-ConfluenceConfig`
- **API** — `Invoke-ConfluenceRestMethod` (the single generic REST entry
point every command wraps)
- **Spaces** — `Get-ConfluenceSpace`, `Get-ConfluenceSpacePermission`,
`Get-ConfluenceSpaceProperty`, plus space administration:
`New-ConfluenceSpace` (create), `Update-ConfluenceSpace` (partial
update), `Set-ConfluenceSpace` (declarative create-or-replace),
`Remove-ConfluenceSpace` (permanent, asynchronous delete)
- **Site / Pages / BlogPosts / Folders / Comments / Labels /
ContentProperties / Attachments / Restrictions / Users** — read/write
commands per area; page edits use `Update-ConfluencePage` (renamed from
`Set-ConfluencePage`, since it performs a partial update and the `Set`
verb is reserved for declarative create-or-replace as in
`Set-ConfluenceSpace`)

Each command documents its required OAuth granular scope in its help,
and errors surface Atlassian's `X-Failure-Category` (for example
`FAILURE_CLIENT_SCOPE_CHECK`) so permission/scope failures are easy to
spot. Every command's help links to its documentation page
(`https://psmodule.io/Confluence/Functions/<Area>/<Command>/`) followed
by the relevant Atlassian API reference.

## New: reusable connections via Context

Credentials and module configuration persist through the
[Context](https://github.com/PSModule/Context) module, declared via
`#Requires` so the build records it as a manifest dependency. Connect
once — the token is stored as a `SecureString`. Store multiple sites or
accounts as named contexts and target any of them with `-Context`.

```powershell
$token = Read-Host -AsSecureString
Connect-Confluence -Site 'msxorg' -Username 'you@example.com' -Token $token -SpaceKey 'DOCS'
$space = Get-ConfluenceSpace -Key 'DOCS'
New-ConfluencePage -SpaceId $space.id -Title 'Release notes' -Body '<p>Hello</p>'
```

## How it is built

- One function per file under `src/functions/{public,private}`, grouped
by resource area; module state in `src/variables/private`.
- No `header.ps1` and no source `manifest.psd1` — the build generates
the manifest, derives the module tags from the repository topics, and
reads the `#Requires` (PowerShell 7.0 and Context) from the source.
- Comment-based help follows the GitHub module style: indented sections,
fenced examples, and a documentation-page `.LINK` first.
- Examples (`Connecting`, `Pages`) and a credential-free surface test,
plus a skipped integration scaffold that reads `CONFLUENCE_*`
environment secrets. Tests require Pester 6.x.

## Tests and secrets

No tenant-specific data is included — examples use generic placeholders.
The integration tests are skipped unless connection details are provided
through the repository's Actions secret and variables
(`CONFLUENCE_SITE`, `CONFLUENCE_USERNAME`, `CONFLUENCE_API_TOKEN`,
`CONFLUENCE_SPACE_KEY`), which this PR wires into the Process-PSModule
workflow through `TestData`. Each public function also carries a
`#SkipTest:FunctionTest` marker so the framework's source-code test
suite passes while per-function tests are deferred.

## Technical details

- Merged `main`: kept the implemented-module README over the placeholder
(#15), adopted the Pester 6.x requirement (#16), and picked up the
Process-PSModule workflow bump to v5.5.7 (#14).
- Validated locally: 0 syntax parse errors, 0 PSScriptAnalyzer findings
(repo linter and framework build rules), every public command's first
`.LINK` resolves to its docs page, and the module assembles and imports
with all 41 public functions.
- Change type is **minor** (new functionality on a pre-1.0.0 module).
Repository topics set to supply the manifest tags;
`major`/`minor`/`patch`/`NoRelease` labels created for the release
automation.
- No linked issue — this work was driven directly; a tracking issue can
be added for traceability. Opened as a **draft** for review.
